Ilker ManapandClaude Opus 5.5 edeeb9f8e1 MCP takes pictures of real size, by id too, and waits for a cold model
The game's bridge found three things on the PoC. /mcp held its body to
64 KiB — the edit meant for it had raised the memory notes' limit instead —
so a 1024 px concept sent as base64 failed as "expected one JSON-RPC
request object". The notes are back to 64 KiB, /mcp takes 64 MB, and a
call past it is a 413 saying so.

/v1/files took batch files only, so a picture could not be sent once and
named after. purpose vision and user_data are kept too, as long as job
results, and generate_mesh hands a workflow model the id as it is.

generate_image and review_images failed at once while their model was
cold. They wait out an answer that says when to come back — loading,
another model holding the GPU, a full queue — for as long as the call may,
saying who holds the GPU and about how long; a refusal that says no
Retry-After, a spent budget, is said at once.

Ilker ManapandClaude Opus 5.5 c22528c26e A model that does not fit its card is not added to fail; weights in use are not removed
CI / test (push) Failing after 30m3s
Apertus 70B with a 65536-token pool, and then 8B with 131072, on a 24 GB
card loaded their weights and failed to make their context on every start,
the 8B taking the card from the 70B each time only to fail. ctl model serve
now shrinks a pool the card cannot hold beside the weights (KV cache from
the GGUF's shape, 90% of the card, a gigabyte for the engine), saying so,
and refuses weights that do not fit at all; the portal's serve form refuses
such a pool and says the largest that fits.

The mirror page removed the 70B's weights while the catalog still had the
model, whose replicas went on loading the node's copy with nothing said.
Removing weights a catalog model loads is refused, naming the model.

Ilker ManapandClaude Opus 5.5 d1e91868ee Setup asks where alerts go, and sends each a test
notify.webhooks existed and setup never asked for one, so a new site
learnt of a parked model or a lost node from its users. `llmgw server
init --webhook URL` (repeatable) and a Notification webhooks field on
both setup screens take them now. Slack's address, Mattermost's and
Rocket.Chat's /hooks/ and Discord's …/slack are sent Slack's text, any
other the event as JSON; slack: or json: in front says which.

Once the control plane runs, they are added to the cluster's settings
beside the webhooks already there, none twice, and setup waits for the
control planes to start again on the change before sending each a test,
saying which answered. A webhook's path is its secret, so it is shown by
host only. A failure is said, not fatal: the cluster serves without its
alerts, and ctl notify test tries again.

Ilker ManapandClaude Opus 5.5 aa531b1053 ComfyUI models of one environment share one replica
flux and sf3d on one card handed it to each other, each starting ComfyUI
and loading its weights from nothing (BACKLOG H3, placement side). An
environment of two or more models now gets a hidden catalog entry,
comfyui-env-<name>: on its first member's profiles with the most memory
any member needs, on demand for the longest idle timeout, carrying every
member's weights, repositories and the environment's custom nodes. The
members get no replicas of their own; asking for one wants the entry.

The agent fetches each member's weights; the gate links all of them,
refusing two weights files of one name, links each member's Hugging Face
repository, and answers /v1/models for every member. The control plane
offers the replica under the members' names with each one's workflow and
checkpoint, which the router sends by the model asked for. A member's
sibling never evicts the replica serving it, and the members' load counts
as the entry's.

Ilker ManapandClaude Opus 5.5 55d5e13534 Pictures, 3D models, a vision model and workflows as tools at /mcp
An agent driving Blender made its concepts, meshes and render reviews
through a tool server of the game's own, which called this gateway; the
gateway's MCP server offered only the memory notes. It now offers
generate_image, generate_mesh, review_images, run_workflow, job_status and
gateway_status beside them, each only where a model for it is here.

Each tool makes its request of the client API as the caller, through the
handler Handler built, key check and all: allowlists, limits, licences
left out, budgets and accounting apply as to any request, and a job is
the caller's. What a tool makes is kept as the caller's file and answered
by id and download URL, since a server over HTTP cannot write to the
caller's disk; a picture comes with a 512 px preview, and whole where no
file can be kept. A picture to work from is a file id, a data URL or
base64; one sent to the vision model is shrunk to 1280 px.

A mesh takes minutes. A client that takes a stream is answered as
server-sent events, with notifications/progress for its token while the
job is queued, waiting for the GPU and running, and waits up to ten
minutes; one that does not waits 50 seconds and gets the job id, which
job_status asks after.

CI / test (push) Successful in 9m12s
Claude Code and the Anthropic SDKs asking for extended thinking got the
answer alone: a reasoning model's reasoning_content was dropped. Asked for,
it comes back as a thinking block before the text — streamed as
thinking_delta events and closed with a signature before the text begins —
and the model is told to think through its chat template
(enable_thinking); disabled tells it not to. Not asked for, it is left out
as before.

One job at a time, a 3D job waiting for the card held up another model's

one running, and starts each in its own goroutine; one ending wakes it for

ctl model serve served one as a chat model: no --embedding, four slots, a
512-token batch, embeddings unset, and a chat smoke test it could not
pass. A GGUF that pools (<arch>.pooling_type), or --embeddings, gets
--embedding, 32 slots of 1024 tokens unless sized otherwise, a batch that
holds a whole passage, the embeddings capability, and one vector asked for
as its smoke test (canaries and updates too). An import of a hundred
thousand chunks had gone at the pace of four slots with the card a third
busy.

A site's nodes stayed a release behind after its control plane was
upgraded, with nothing printed to say so. ctl upgrade checks every node's
version once the waves are done, fails naming any not on the release, and
says when the control plane has no nodes registered. llmgw upgrade on a
control plane, which looks like the cluster's upgrade and is not, says how
many nodes it left behind and the command that upgrades them.

CI / test (push) Failing after 6m28s
Stable Fast 3D takes the light out of the picture it sees, and a dark
basalt (median 0.17) came back a light stone dimly lit (0.67). The save
node takes albedo_match, the picture and its mask, and scales the base
colour texture in linear light by the ratio of the object's medians, so
marks keep their contrast; texels nothing maps to are left alone. On the
game team's rock it is 0.18.

A workflow's {{name|false}} default now fills a BOOLEAN input with a
boolean rather than the word.

Ilker ManapandClaude Opus 5.5 848db08469 The cluster page and the console say which picture and 3D models are here, and add them
CI / test (push) Failing after 6m27s
A site whose catalog had no flux-schnell or triposr showed no Images or 3D
page, and nothing said they were one click away. The cluster page now has
a Pictures and 3D models card under the models: each preset, what it
makes, the classes of card here it fits, whether and by whom it was
added, and why the leader has not added it by itself; an Add button, which
says first when it would install ComfyUI on the GPU nodes and restart the
control planes; and the switch for presets.auto. The console's models
screen shows the same under its table: A adds one, asking first in the
same case, and P turns automatic adding on or off.

`ctl model add PRESET` and `ctl model presets` go through the presets API,
so the control plane keeps who added one, and `ctl model presets auto
on|off` flips the setting; against a control plane from before, add sends
the entry as v0.14.4 did.

Ilker ManapandClaude Opus 5.5 f42af27da5 The leader adds the picture and 3D presets a node fits, unless told not to
A customer's portal had no Images or 3D pages: nobody had written a
definition for either, on a cluster whose V100 runs both. The leading
control plane now adds flux-schnell and triposr, on demand, once a node
has a card that fits one, the cluster installs ComfyUI, and the catalog
makes nothing of that kind. presets.auto (a live setting, on by default)
turns it off; a preset somebody removes is recorded as declined and not
added back until added again by hand. Each addition is in the audit log.

GET /api/v1/presets says how each preset stands, the ComfyUI the cluster
installs, and why one is not added; POST /api/v1/presets/{name} adds one
(setting engines.comfyui where there is none); PUT /api/v1/presets/auto
switches it.

Ilker ManapandClaude Opus 5.5 40b8948d7d A picture or 3D model is added by its name: llmgw ctl model add triposr
flux-schnell and triposr come with llmgw as presets: their workflow,
custom nodes, packages and licence as they were found and tried on the
PoC, and a profile that says the card it needs rather than a class, so the
entry places on any site's cards. TripoSR's workflow is built in, with the
LLMGWPrepareForMesh node that keeps a picture's background out of the
mesh, which the copy in the document had left out.

`ctl model add PRESET` adds one, and has the nodes install ComfyUI when
the cluster's settings name none; `ctl model presets` lists them; the
console's add-model dialog offers them beside a definition file. A
ComfyUI build is now also checked to keep its order on a Turing card, so
a node's installed cu13 is not replaced by the cu126 build.

Ilker ManapandClaude Opus 5.5 52898fbb80 A V100 gets a ComfyUI it can run, and an open driver is read by its version
PyTorch's CUDA 12.8 and 12.9 builds start at Turing since torch 2.8, as
CUDA 13 does, so on a V100 both ComfyUI builds were installed, 10 GB each,
and failed on the card with "no kernel image". The cu129 build now needs
7.5, and a third, on PyTorch's CUDA 12.6 torch, carries Volta and Pascal.

The open kernel module, NVIDIA's default since 560, writes "Open Kernel
Module for x86_64  580.82.07" in /proc/driver/nvidia/version, and the word
after "Module" was taken as the driver: "for". With the driver unknown,
every build was tried whatever driver it needs.

Stable Fast 3D's texture_baker and uv_unwrapper are C++/CUDA packages no

builds each as a wheel with ComfyUI's Python, for the compute capability
torch reports for the replica's own card, keeps it on the node by the
node's commit, the architecture and the directory, and installs it
beside the replica with the node's requirements. A copy in ComfyUI's
environment does not pin it. A node with no CUDA toolkit says so.

comfyui.huggingface_repo shows the replica's weights to a node that
loads them by repository name, in the engines' Hugging Face cache, so a
gated repository needs no token on the node.

CI / test (push) Failing after 6m19s
A catalog entry meant for many sites cannot know their GPU class names:
the PoC has a Quadro RTX 6000, a customer an A100, another an L40S. A
profile may now say gpu: {min_compute_capability, min_memory_gb} in
place of gpu_class, and stands for every class in the cluster that meets
it, named <profile>@<class>, at its own priority; placement still sees
exact classes. ProfileByName and EngineProfile resolve such a name to
the profile on that class, so every caller that maps a replica back to
its profile works unchanged. A ComfyUI profile may carry its own
workflow, checkpoint and nodes, and with its own source an fp8 workflow
and weights go to cards with fp8 and fp16 ones to Turing.

A profile by need is left out of placement until the cluster's cards are
known: with no class it would have read as a CPU profile.

CI / test (push) Successful in 9m7s
A model's catalog entry now says what its workflow takes and makes:
comfyui.inputs, each a placeholder of its name with a type (text, int,
float, bool, choice, image, mask, audio, video, file), bounds, choices
and a default; and comfyui.output, which gains video, audio and files
beside pictures and meshes. POST /v1/workflows/runs with {model, inputs}
checks a request against them before a job is written — a required input
left out, an unknown one, a number out of bounds, a song sent as a
picture, another owner's file id are each refused with what was wrong —
and the job worker replays it to a replica, where the files go into
ComfyUI's input directory, the workflow is filled and run, and the first
file of the model's output kind is the job's result. /v1/models lists
each ComfyUI model's workflow, so a client can build its form.

A PNG result carries the licence in an iTXt chunk, as a GLB does in
asset.extras. A file whose server named no type is typed by its name
before its bytes, so a WAV is audio/wav, not audio/wave.

CI / test (push) Failing after 6m21s
A ComfyUI model may name an environment: the models of one environment
agree on every custom node they both name and on every package range,
so one replica can carry all of them and ComfyUI moves between their
weights itself rather than the card being handed over with a cold start
each time. The catalog refuses an environment that cannot share a
Python, naming both models; Catalog.Environments gives each one's
models, the union of their nodes and their weight sources, for
placement to build on.

A licence gains an id (SPDX where there is one), whether its output may
be used commercially, the regions it excludes, a revenue cap and the
attribution it asks for, so a person's or a site's choice of licences
can be matched without reading prose.

BACKLOG gains section H: ComfyUI as a platform.

After a control plane restart flux, adopted and asked for by nobody, had no
last use and so was never idle enough to evict: a 3D job waited out its
whole fifteen minutes with no estimate. It counts as used at adoption, as it
is already counted as wanted then; a replica in use is reported by the
router within seconds.

Ilker ManapandClaude Opus 5.5 95c61daf1b Jobs are served by the leader, and a moment of fitting nowhere is waited out
CI / test (push) Failing after 8m47s
A 3D job leased by the standby control plane, whose router has no endpoints
and which a job replayed in the process never leaves, was told "loading"
for seven minutes while the leader served the jobs behind it. Jobs and
batches are claimed only while leading.

Five jobs asked for while cuda01's agent restarted failed for good as
"cannot be placed": re-registering, the node had no engines for a few
seconds. A job asks again for five minutes before that is its end.

A 3D job waiting for the picture model to give up the one card had an empty
progress; its client could not tell waiting from stuck. The control plane
says which model holds the cards and when it lets go, plus the waiting
model's last start; the 503 carries it as headers, and a job keeps it as
progress {state: waiting_gpu, held_by, eta_seconds}.

A 3D job asked for straight after a picture, on a cluster with one card,
failed at once with "cannot be placed": flux held the card, too freshly
started to evict. The cards coming back when an on-demand model goes idle

so it needs none.

/3d beside /images, while some model makes meshes: a picture chosen, the
job asked for through the same path an API client's takes, its progress
shown (waiting for the card, n ahead; making it, the node and percent),
and the mesh in a viewer — model-viewer 4.4.0 (Apache 2.0, with three.js
and lit), served from the gateway since the page's policy loads scripts
from nowhere else — with a download and the model's licence. The mesh is
served to its owner from /3d/jobs/{id}/file; another project's person is
told there is no such job.

A job made from the portal acted for a key that does not exist: the
worker now rebuilds a session's principal from the account that made it,
while it is active and still in the project the job is charged to.

Ilker ManapandClaude Opus 5.5 88781cfcfe A job says how far along it is; a ComfyUI model brings its custom nodes
G2: the gate keeps a websocket open to its ComfyUI under a client id of its
own, puts that id on every workflow it lets through — ComfyUI tells only
the client that queued a workflow how it goes — and keeps the last word on
each: the node running, its step of how many. It answers at
/progress/{prompt_id}. While a job's request waits, the router reads the
queue (queued, n ahead) and the gate (running, node, step, percent) and
writes it into the job, which a client reads back. Only into a job of the
same key: a tag naming another's job writes nothing.

G3, the rest of the plumbing: comfyui.nodes names custom nodes by https
repository and full commit, with the PyPI packages they need. The gate puts
each in the replica's own custom_nodes at that commit and installs the
packages beside the replica, constrained to the versions ComfyUI's
environment already has, which it never changes. The catalog refuses a
branch for a commit and anything but package specs for requirements. An
OBJ a node saves leaves the gateway as a GLB, colours kept, so every mesh
can carry its licence.

Ilker ManapandClaude Opus 5.5 c87e413360 A ComfyUI model may make meshes: from a picture, with its licence inside
G3, the part that needs no model: a ComfyUI model's comfyui.output (or
external.output) says pictures or meshes. A request for a 3D model — a
job at /v1/3d/generations — carries the picture as base64; at the replica
it is uploaded to ComfyUI's input directory (the gate lets /upload/image
through), the workflow is filled in with its name, the seed and the
resolution, and the mesh the workflow saves comes back with its type,
which is the file the job keeps. comfy.Client reads every list of files an
output names, not "images" only, and types a file by its extension where
ComfyUI sends octet-stream.

A model's license (name, url, notice) is said in /v1/models and in the
job, and written into a GLB's asset.extras, since the file travels without
the API; a mesh it cannot be written into is refused. per_mesh in
auth.pricing, usage.meshes in the rows, the sums and the export
(migration 0045). A picture asked of a mesh model, or a mesh of a picture
model, is refused saying which it makes.

A knowledge-base import sends far more than the cluster can take at once,
and every band waited the same 30 s. A band now has its own queue_ttl, so
one for bulk work waits behind people instead of being turned away.

And a request turned away because the cluster stayed busy — the queue
full (503) or waited as long as its band may (504) — now carries
Retry-After: 10. Without it llmgw-kb, which retries only what says when
to, counted each such passage as failed; that is what turned parts of the

Ilker ManapandClaude Opus 5.5 fde1501e8a ComfyUI as an engine of the cluster's own
A model whose profiles run engine comfyui is placed on a node's card like
any other, and makes pictures there. ComfyUI asks for no key, so the agent
starts it behind llmgw comfyui-gate: ComfyUI on the loopback, the gate on
the replica's port demanding the replica's key and letting through only
what the router asks — queueing, waiting, fetching, cancelling. The gate
answers the agent's /health and /v1/models, shows ComfyUI the fetched
weights by their own names, and gives each replica its own base directory.
ComfyUI runs as the gate's child, so its card memory is the replica's.

A node offers the engine when agent.yaml names its ComfyUI
(engines.comfyui.dir). The model's comfyui: block names the workflow and,
for a source that is a set of files, the checkpoint.

Ilker ManapandClaude Opus 5.5 79a503f824 A picture from ComfyUI loses the workflow written into it
ComfyUI saves the whole workflow — prompt, checkpoint, nodes — as PNG text
chunks in every picture. They are taken out before the picture is sent.

Ilker ManapandClaude Opus 5.5 2f06c0e513 Pictures from ComfyUI at /v1/images/generations
An external model with api: comfyui is a ComfyUI server. A request for
pictures goes through the same key, allowlist, limit, admission and guard
checks as any other; at the replica it becomes a workflow — a built-in
(flux-schnell, flux-dev) or a JSON file in API format, with {{prompt}},
{{width}}, {{seed}} and the like filled in — queued, waited on, and its
pictures sent back as b64_json. A client that leaves takes its workflow
off the queue or interrupts it. ComfyUI is never scraped for metrics.

Ilker ManapandClaude Opus 5.5 6b7750a0dd An embedding model's query_prefix, put before questions and never before documents
Qwen3-Embedding and models like it are trained with an instruction on the
query side only. The prefix goes before the question a knowledge-base
search embeds, at answer time and in the admin API's search; documents
reach /v1/embeddings from llmgw-kb as they are.

It sat in localStorage under one fixed key, so the next person to sign in
on the same browser opened the chat on the last one's conversation. It is
now kept under the account's id, anyone else's is dropped when the page
loads, and signing out sends Clear-Site-Data: "storage" so nothing the
pages kept outlives the session.

llmgw-kb sends many passages in one /v1/embeddings request. Their sizes
were added together and compared with the context, so a batch of passages
that each fit was refused as one over-long prompt. The longest input is
what has to fit; the total still counts for usage and limits.

Ilker ManapandClaude Opus 5.5 8df78a4d41 The firewall setting reaches the mirror machine and the store's members
The leading control plane tells the mirror over its API (PUT /v1/firewall,
kept as .firewall.json beside the models and applied by the same path unit
control planes use), and keeps the state in the store's cluster_state for
members that run no llmgw, which a root timer reads from the member's own
copy. The mirror also lets in the network of every node and control plane
the leader knows. Tried on the PoC: off, on and a network added, on every
kind of machine.

What llmgw org, keys and users did against the store on a control plane
can now be done remotely and by automation: the tree read, added to,
renamed, moved and emptied; keys issued (the key in the answer, once),
listed and revoked, with the scopes' lifetime limits; people put in and
taken out of the tree, their keys in projects they no longer reach
revoked with it.

Ilker ManapandClaude Opus 5.5 9c675e7293 Knowledge bases at scale: halfvec, a text index per collection, ef_search raised to the candidates wanted
A search asking for more than 10 passages got at most 40 candidates from
HNSW, pgvector's default ef_search. The full-text arm scored every chunk
holding a word of the question before limiting, over the whole
organization's GIN index; it now takes candidates by ts_rank from the
collection's own partial index and scores those. New collections index
halfvec on pgvector 0.7 and later (up to 4000 dimensions).

Ilker ManapandClaude Opus 5.5 42d3b7ea22 The store's PostgreSQL sized to its machine's memory
Each Patroni member gets a share of its own RAM in its own config.yml:
shared_buffers a quarter (15% beside a control plane or agent),
effective_cache_size, maintenance_work_mem and work_mem scaled to it, all
clamped. It is read again on every server init --patroni, so a machine
given more memory gets the use of it. A single-machine PostgreSQL init
installs is sized the same way, as a shared machine, instead of a fixed
96MB.

The step itself went in with 85025df by accident, in an early form that
restarted PostgreSQL before Patroni had taken the reload, leaving the old
shared_buffers with a restart pending. It now waits for Patroni to report
the restart pending, restarts with restart_pending (replicas first, the
leader last), and restarts a member it finds pending from an earlier run.

Applied to the PoC: pg01 978MB, ctl02 (control plane beside it) 587MB,
both from 128MB; streaming, lag 0, gateways unaffected.

Ilker ManapandClaude Opus 5.5 85025dfb03 Trained adapters published, private to their owners like the knowledge bases they come from
An adapter now has an owner (org, team, project, user or key): only callers
there see it, and to anyone else it is a model that does not exist, absent
from /v1/models too. A training job's owner defaults to the one collection
its pairs come from, must be able to read every collection they come from,
and pairs from a knowledge base are never made public. ctl train publish
keeps the GGUF or PEFT files on the mirror, which accepts uploads now, and
sets the owned adapter after the usual architecture check.

The knowledge bases' cache_salt follows the collections searched rather
than the organization, so two teams of one organization no longer share
cached passages.

Ilker ManapandClaude Opus 5.5 79b3e9f887 LoRA adapters trained on the nodes: llmgw ctl train
A job names the catalog model the adapter is for, the safetensors weights to
train on, the node and the MiB of a card it needs, and question/answer pairs.
The control plane sends it when the node's agent is there and nothing else
trains on it; the agent trains with its installed vLLM's torch and a pinned
overlay of peft and accelerate (no second environment), as the engines'
user, on the card with that much free — beside an engine, if it leaves that
much — converts the adapter to GGUF with the installed llama.cpp's own
conversion code when the model is served by llama.cpp, and sends what it
made back in pieces, kept in the store to download. Progress, loss and peak
card memory are reported as it goes; a node that goes fails its job.

change; an agent whose settings changed checks they load beside its file,
keeps them and starts again on them, engines serving throughout. An edited
agent.yaml that loads restarts the agent too. History, audit, ctl config, the
console and the portal's settings page cover them as the rest of the

kb default, POST /api/v1/kb/defaults, and the console's Knowledge screen. A
request's own X-Llmgw-Knowledge overrides it and none turns it off. A default
never refuses a request: a collection the caller cannot read is left out, and
a failed search answers without passages. Removing a collection takes it out

a full-text match, each search brings four times k candidates, the text

when the embedding model did not answer rather than quietly searching text.

so a rerun reads nothing unchanged, a file skipped stays skipped until
--retry, and --delete removes only what this machine sent under the paths
given. --dry-run says what would leave the machine. Commands: login,
collections, sync, status, history, formats.

A site had "continue" refused. Qwen3Guard-Gen 0.6B gave the ordinary ones
0.15 at the most and the harmful ones 1.00, in 0.8 GB on CPUs.

Ilker ManapandClaude Opus 5.5 63f7c8cfd7 llmgw start --wait waits for the models, not for the setting
CI / test (push) Successful in 3m57s
Every model of a stopped system asks for no replica and so has what it asks
for. Until the control plane took the setting up, seconds later, start
--wait saw 18 of 18 satisfied and returned at once, with nothing started.
It now counts only once the control plane says it is in the state asked
for, both ways.

Ilker ManapandClaude Opus 5.5 2d14918b99 An adopted engine that turns ready after registration is reported
The registration carries each shard's state as it is then. An adopted
engine is health-checked after that, and nothing reported the ready that
followed, so when the agent registered first the control plane kept the
replica starting while it served. After llmgw restart on the PoC two
replicas stayed so, one the only replica of qwen2.5-coder-14b. The
session's watcher now reports every shard the registration called not
ready once it is.

One standby that ssh could not log in to stopped the whole restart before
this control plane's own. It is now said and left, the rest restarts - the
leader last - and the command fails at the end naming what was not
restarted and how to do it there.

Ilker ManapandClaude Opus 5.5 7245dbe1dd llmgw stop, start and restart act on the whole system
Issue #3 asked for commands to stop and start the system, and 05aa21c gave
only one machine's services. Now:

- llmgw stop sets serving.stopped in the cluster's settings, live: the
  reconciler wants every model at no replicas, freeing every GPU, and the
  gateway answers every POST under /v1/ with 503 system_stopped. The control
  planes, agents and mirror keep running, and no model's definition changes.
- llmgw start clears it; every model is placed again as it asks.
- llmgw restart has every agent restart over its stream (RestartAgent), then
  the other control planes over ssh, standbys before a leader, then this
  one; engines keep serving.
- llmgw status is the cluster's summary, saying when it is stopped.

One machine's services moved to llmgw service status|start|stop|restart.

Ilker ManapandClaude Opus 5.5 2f595f5999 An adopted engine's state is written without its command; engine-check finds the installed build
CI / test (push) Successful in 3m46s
SetCompute on an engine adopted from an earlier agent called writeState,
which read the command line from sh.cmd - nil for a process this agent did
not start - and the agent crashed at every start on the PoC's nodes until
fixed. An adopted shard now keeps the command line its state file had.

engine-check looked for llama-server one directory too shallow; the agent
installs it under <version-variant>/llama-<build>/. It now looks at both,
preferring a CUDA build on a machine with NVIDIA GPUs. Run on cuda01: a
token computed on CUDA0, 25 of 25 layers offloaded.

Ilker ManapandClaude Opus 5.5 b5d650af16 What a replica computes on comes from nvidia-smi; llama.cpp says its layers only at -lv 4
Checked against the installed llama.cpp (b10991): at its default verbosity
it prints neither the devices it uses nor the layers it offloads, so the
start-up output said nothing and every replica's ON column stayed empty.
The agent now takes compute from nvidia-smi - the GPUs the shard's processes
hold memory on, and how much - or CPU, for every engine, falling back to it
when llama.cpp's output says nothing; adopted engines get it too, and each
session reports it once per shard as a compute-only status. engine-check
runs its GPU token at -lv 4, where llama.cpp does say where its layers went.

Ilker ManapandClaude Opus 5.5 25b3e129fe What a shard computes on survives the agent's and the control plane's restarts
It was sent once, with READY, and kept only in the leader's memory: a
failover or an agent restart lost it. The agent now keeps it with the
shard's state on disk (ShardSpec.Compute, set by Supervisor.SetCompute) and
reports it with each running shard when it registers (RunningShard.compute),
which adoption carries onto the replica.

The settling window ran from process start, so a standby that took over
after a minute placed at once, before the agents reconnected and reported
what they run: it started second copies of replicas it did not know of and
drained the healthy ones when they were adopted. Seen on the PoC: a leader
restart replaced llama-guard-3-1b and a qwen2.5-1.5b replica. Reconcile now
reopens the window on the first pass after standing by.

/forgot mails a link to set a new password when the cluster's mail settings
say how - SMTP relay, sender, and the public base_url the link points at,
never the request's Host - and says the same whether or not the address has
an account. /reset sets it once, closing every session. Links are kept by
their hash in password_resets, good for an hour, a newer one replacing an
older. Without mail, /forgot says to ask an operator, and llmgw users
reset-link makes the link to hand over. Single sign-on accounts get none.

A model's replicas restarted one at a time, always. RestartPace says how
many restart at once: MaxSurge beside themselves (replacement first),
MaxUnavailable stopped first (no room needed, out while loading); the

max_surge and max_unavailable on POST /api/v1/restart.

Ilker ManapandClaude Opus 5.5 e4e15200d6 engine-check computes a token on the GPU, and finds the installed llama.cpp
Seeing a device is not computing on it. For llama.cpp on a machine with
NVIDIA GPUs, engine-check now loads a small GGUF (--model, or the smallest in
the weights cache) with every layer on the GPU, asks for one token, and
reads from llama.cpp's own output where the layers went: a build that
computes on the CPU fails, naming the fix. With no --bin it checks the build
the agent installed under /opt/llmgw/engines.

Ilker ManapandClaude Opus 5.5 0bd0d881c5 A replica says what its engine computes on, and llama.cpp's word on the CPU refuses a GPU placement
llama.cpp's start-up output is read as a shard becomes ready: the devices it
used, its backend, and the layers it offloaded. That goes up with READY in a
new ShardStatus.compute, is kept on the shard, and is shown by the admin
API, ctl replicas (ON) and the console (COMPUTE). A shard given GPUs whose
engine says it found no usable GPU or offloaded no layer is stopped and
failed, even where nvidia-smi cannot be asked.

## F. Company documents: knowledge bases (RAG), then adapters (2026-10-08)
A company wants a model to answer from its own documents. Retrieval is the
tool for *knowledge* (sources shown, re-indexed in minutes, access per
tenant); LoRA training is for *behaviour* (vocabulary, format) and has no
access control — whatever goes into weights reaches everyone who may use the
adapter. RAG first. Decisions taken: access per collection (no per-document
ACL yet); a personal key or session names a project or team and gets that
chain only, never the union of its person's memberships; PostgreSQL store
only, off on SQLite with a sentence saying why.
### F1. Store: collections, grants, chunks (M) — done 2026-10-08 (branch `rag`)
Built (`internal/store/knowledge.go`, migration 0035 PostgreSQL only):
- `kb_collections` (owner scope/id, org, embed_model, dims), `kb_grants`
(read|write, any scope, never across organizations; a key needs a
project; a person needs a membership in the organization),
`kb_documents` (digest: the same again is no change, a new one replaces
in one transaction).
- `kb_chunks` is created when the store opens, not in a migration (a
migration needing an extension would stop the control plane; one that
skipped it would never run again): partitioned by organization (hashed
partition name), `tsv` generated (`simple`), GIN on the parent, one
partial HNSW index per collection on its organization's partition
(`embedding::vector(dims)`, `WHERE collection = '<id>'`). EXPLAIN on
20k rows: partition pruned, that index used, policy applied.
Later (scale, 2026-10-08): a partial GIN per collection too
(`kb_tsv_<id>`, backfilled at open); `vec_type` per collection, `halfvec`
on pgvector ≥ 0.7 (up to 4000 dims); `SET LOCAL hnsw.ef_search` to
candidates(k) clamped 40..1000 (EXPLAIN: 40 rows without it, all with
it); the text arm takes candidates by `ts_rank` in a subquery and scores
only those.
- RLS FORCEd on `kb_chunks` against `llmgw.kb_org`/`llmgw.kb_collections`
(set with set_config per transaction), one role — the table owner — not
a separate one. Chunks are deleted by the foreign-key cascade from their
document, which RLS does not block.
- `CollectionsFor(Effective, write)`: owner or grant anywhere on the chain;
no organization (personal key without a project) reads nothing.
- `SearchChunks`: per collection nearest-neighbour (literal id and cast so
the partial index is used) plus a full-text arm with any word
(`a | b`, lowercased by the database, not Go), fused by reciprocal rank.
- Deleting a project/team/org that owns collections is refused like one
with members (changed from "deleted with them": every other delete in the
tree refuses); DeleteUser/ForgetUser delete the person's collections;
deleting an organization drops its partition; grants to a deleted scope go.
- `server init` installs `postgresql-N-pgvector` / `pgvector_N` and enables
it; pgha installs it on every member at setup and enables it on the
leader on every run. Neither stops on failure.
Left: a cluster set up before (the PoC) gets no package from a rerun of
pgha on a running cluster — install by hand or add an upgrade step;
`server restore`/`CopyTo` do not carry kb tables (SQLite → PostgreSQL only,
and SQLite has none); tests need `LLMGW_TEST_POSTGRES` pointing at a
pgvector database as a non-superuser (a superuser bypasses RLS).
### F2. Ingest on the user's machine (L) — done 2026-10-08 (branch `rag`)
Uploading whole files to the control plane was dropped: a PDF is 20–100×
its text, and the work belongs where the files are. Instead a small client,
`llmgw-kb`, run by the person on their own machine with their own key:
- **Its own binary** (`cmd/llmgw-kb`), for Windows, macOS and Linux on amd64
and arm64. `llmgw` itself does not build on Windows (agent syscalls), and
employees' laptops should not carry the server, agent and setup screens. A
test keeps server packages out of its imports.
- `llmgw-kb sync <collection> <dir|file…> [--include/--exclude globs]
[--dry-run] [--delete]`: scan → local catalog (path, size, mtime, sha256;
cache under os.UserCacheDir, digests not recomputed for unchanged files)
→ the collection's manifest from the gateway (name → digest only) → diff
→ for new/changed files only: extract, chunk, embed through the gateway's
`/v1/embeddings` with the person's key (its accounting, limits, guard and
band apply), and send name, digest, chunk texts and vectors; `--delete`
removes documents whose files are gone. `--dry-run` lists what would leave
the machine and how much. A file that cannot be read (locked, unsupported,
no text) is skipped with the reason; the run goes on.
- **Formats, as many as possible.** Built in, pure Go: PDF (text layer),
DOCX/XLSX/PPTX, ODT/ODS/ODP, RTF, EPUB, HTML/XHTML, EML (text and HTML
parts), Jupyter notebooks, subtitles (SRT/VTT), CSV/TSV, JSON/YAML/XML,
Markdown/RST/AsciiDoc/Org, plain text and source code; ZIP archives
recursed into. With a helper found on the machine: legacy DOC/XLS/PPT, RTF
and anything else LibreOffice opens (`soffice --headless --convert-to`),
images and scanned PDFs through Tesseract (`tur+eng`). Text in UTF-8,
UTF-16 (BOM) or Windows-1254/1252 is converted to UTF-8.
- **Across systems:** document names relative to the synced root, `/`
separated, Unicode NFC (macOS hands out NFD), a warning for two names that
differ only in case; CRLF → LF; key from `LLMGW_API_KEY` or `llmgw-kb
login` (os.UserConfigDir, 0600 where that means something); the system's
CA store, `--ca` for another.
- **Gateway endpoints** (client listener, person's key):
`GET /v1/kb/collections` (what this key may read/write),
`GET /v1/kb/collections/{id}/manifest`, `PUT
/v1/kb/collections/{id}/documents` (one document per request: name,
digest, bytes, chunks with text and embedding; dims checked, chunk count
and size bounded), `DELETE …/documents?name=`. Write needs a write grant
or ownership on the key's chain (`CollectionsFor(…, write)`); otherwise
404.
- **Administration** stays with operators: `llmgw ctl kb
create|list|delete|grant|revoke|docs`, admin API `/api/v1/kb`, audit,
console screen; `docs/knowledge.md`.
- Trade-off accepted: vectors come from the client, so a writer could store
vectors that do not match their text — only in collections they may
already write.
Built: `internal/kb/extract` (formats above; helpers found on PATH and in
each system's install places), `internal/kb/chunk` (≈1800 characters under
the heading path, a paragraph of overlap, sections kept apart once a chunk
is a third full), `internal/kb/kbsync` (ledger in SQLite at
os.UserConfigDir/llmgw-kb/ledger.db: documents keyed by gateway, collection
and name with file, size, mtime, digest, state, reason; runs), `cmd/llmgw-kb`
(login, collections, sync, status, history, formats), `internal/router/kb.go`
(the four gateway endpoints, `X-Llmgw-Project` for personal keys, audit),
`internal/control/adminapi/kb.go` + `llmgw ctl kb` + console Knowledge
screen, `docs/knowledge.md`; CI builds the client for all six targets and
releases attach it. Tested: every format from generated fixtures and a
Turkish PDF (OCR path with Tesseract here), sync against a fake gateway and
end to end against the router on pgvector.
Tried on the PoC 2026-10-08 (control planes 140 and 150 on a dev build of
this branch; their previous binary is /usr/local/bin/llmgw.pre-rag): Ubuntu's
pgvector 0.6.0 installed on 149/150 and enabled; bge-m3's weights were never
in the mirror (fetched from CompendiumLabs/bge-m3-gguf@1864f47f) and it is
held at 1 replica; tree Demo/ik/belgeler and Demo/satis/crm with a key each;
collection Demo/politikalar filled from a Mac through an SSH tunnel with ten
Turkish files in nine formats (9 sent in 5 s, the .doc skipped for want of
LibreOffice; a rerun sent nothing in 0 s; a changed file alone was sent).
Nine Turkish questions each found their page first once search scored by
similarity plus word coverage (rank fusion had got two wrong). The other
team's key saw no collection and got 404 by id; with a read grant it read
and could not write; revoked, nothing again. On the live store the llmgw
role (not superuser, no BYPASSRLS) sees 0 chunks with no scope set and 0
with the organization alone.
Left: the gateway's collection list shows the owner as team:ID, not its
path; no LibreOffice on the dev machine, so the legacy
Office path is untested beyond its error; the client is unsigned (Gatekeeper
and SmartScreen warn); Outlook `.msg` is not read; one document over ~60 MiB
of JSON (a few thousand pages) is refused rather than split.
PostgreSQL tests of store, router and adminapi share LLMGW_TEST_POSTGRES and
the store's TRUNCATE each test; run them with `go test -p 1` or one package
at a time, or a router test loses its rows mid-run.
### F3. Retrieval on the request path (M) — done 2026-10-08 (branch `rag`)
- `llmgw.knowledge: [collections]` in the body (stripped before the
engine), or default collections per project/key.
- Allowed set from the caller's chain (§7.9.2), cached like limits; grants
add up down the tree. Personal keys and sessions need `x-llmgw-project`
(or the playground's picker) naming a scope the person is a member of.
- A collection not allowed answers 404, exactly as a missing one.
- Hybrid search with the filter inside the query (per collection, its own
partial index; pgvector 0.6 is enough —
scored by similarity plus the share of the question's words held (built
in F1/F2 as SearchChunks), `/v1/rerank` when a reranker is in the catalog. Top
chunks into a system message with document and position;
`x-llmgw-sources` lists them.
- Leaks closed: answer-cache key includes the allowed set; per-organization
`cache_salt` on RAG requests; injected passages under `no_store` and the
guard's prompt-injection check; returned doc ids in the audit.
- Done: router tests that tenant B never receives tenant A's chunks
(including via cache), that a personal key without a project is refused,
metrics (retrieval latency, chunks returned), docs.
Built (`internal/router/rag.go`): `X-Llmgw-Knowledge` (header, as the
other llmgw extensions are, not a body field), `X-Llmgw-Knowledge-K`;
collections from the key's chain (kbEffective, shared with the kb
endpoints), 404 for one not readable; the question embedded through the
ordinary path on the caller's principal; SearchChunks; passages trimmed to
the model's context; added to the one leading system message (or a new
one); `x-llmgw-sources`; before guardInput; never cached; metrics. Default collections built (kb_defaults on org/team/project/key, narrowest
wins, 30 s cache, `ctl kb default`, console action; never refuse); the
portal chat's Documents picker (collection, default or none; sources listed
under the answer; a header the page sends itself is dropped). `cache_salt` per organization on requests given passages, sent to vLLM
replicas only (chosen replica's engine). Checked on the PoC 2026-10-08:
vLLM 0.30.0 (cuda01) with TinyLlama-1.1B AWQ run by hand beside the 35B in
the card's last 2.3 GB — a 668-token prompt reused 656 tokens under the same
salt and 0 under another's, with identical text (llmgw cannot place it
there: placement takes whole GPUs). Live on the PoC: a team default answers
a request without the header, `none` turns it off, an explicit header with
k=2 gives two sources and no more, llmgw-kb lists owners by path. Left: returned passages
are not audited per request (the header and the kept request record them).
### F4. Adapter training (L, after F1–F3) — done 2026-10-08 (branch `adapters-f4`)
A run-to-completion job placed by the control plane like a replica and
supervised by the agent like an engine, in a Python environment the agent
installs (TRL + PEFT, QLoRA). Data: Q/A pairs generated from a collection by
a cluster model through `/v1/batches`, reviewed by people. Output to the
mirror, into the model's `adapters`, through canary and a quality suite.
Runs when the scaling schedule frees a GPU; 8–14B dense bases on one card.
Never train on a collection some users of the adapter may not read.
Tried 2026-10-08 on the PoC, by hand: Qwen2.5-0.5B-Instruct (fp16) with a
LoRA (r=16, every linear layer, 8.8M trainable), trained beside the 35B in
cuda01's last 2.3 GB (peak 2158 MiB on the card, 64 s for 138 steps, PEFT in a
venv over the vLLM engine's torch). Data: 90 Turkish Q/A pairs a cluster
model wrote from the nine Demo/politikalar documents, through the gateway.
On nine questions it had not seen, phrased otherwise: base 0/9, 6 epochs
4/9, 4 epochs at a lower rate 2/9. Wrong answers mixed facts across
documents (the meal card's amount, the office day). The same nine through
retrieval: 9/9 with sources. So F4 is for format, vocabulary and tone, and
facts come from F1–F3; a bigger base on a free card would do better but not
change that. The training itself fits a small slot on a shared card, which
the job design can rely on for small bases.
Built: `ctl kb dataset` (POST /api/v1/kb/collections/{id}/dataset, NDJSON
with each pair's collection); train_jobs/train_artifacts (migrations 0037,
0038 owner); internal/control/train (queue, one job per node, artifacts in
1 MiB pieces, a node that goes fails its job); internal/agent/train (the
newest vLLM's python3 + `uv pip install --no-deps --target` peft 0.21.2 and
accelerate 1.15.0; llama.cpp's conversion code for the installed release,
untarred from its source; the card with the most free memory, if enough;
runs as llmgw-engine); `ctl train start|list|show --follow|cancel|rm|
download|publish`; the mirror's PUT /v1/models/{model}/{version}/{file};
publish uploads the GGUF (llama.cpp) or PEFT files (vLLM) and sets the
adapter after checkAdapters. Owners: catalog.Adapter.Owner, enforced in the
router (404, hidden from /v1/models); a job's owner defaults to its single
collection's owner, must be able to read every collection the pairs came
from, and pairs from a knowledge base are never public. Tried on the PoC:
dataset of 90 pairs in 89 s; a job trained beside the 35B (peak 2214 MiB,
138 steps in about a minute) and sent back PEFT and GGUF.
Left: a job dies with its agent's stream (no resume); no console screen for
training yet; quality gating of a published adapter is by hand (ctl eval).

### F5. Large imports (M) — measured 2026-10-09, open
The metallurgy corpus (2,314 files, 108,779 chunks, bge-m3 on the one
GPU) went in at about 25 chunks/s, the same over a phone hotspot and the
LAN. The engine's slots were the limit: llama.cpp `--parallel 4` embeds
four texts per pass, while llmgw-kb sends 32 a request from 6 workers. The
usage rows show 4.6 s a request on average, 1.8 s of it in the gateway's
queue and 0.04 s in the guard. The GPU sat at 18–50% and the store machine
at a third of its CPUs.
- An embedding model's profile with many slots by default (`--parallel`
32–64, `--ctx-size` to match, `--batch-size`/`--ubatch-size` at least the
longest chunk), or `ctl model serve` choosing that for a model with
`capabilities.embeddings`. With the default 512, one 516-token chunk failed.
- Embedding on the gateway's side of a document PUT, so the client sends
text only: today an embeddings answer is ~21 KB of JSON a chunk, and
the text and vector go up again (~11 KB).
- The store next: HNSW inserts took half of one of pg01's two cores; at a
million chunks the vectors alone outgrow its 4 GB. halfvec (pgvector ≥
0.7) and a larger store machine.
- Done: a batch of embeddings checked text by text against the context
(branch `embeddings-batch`); it was refused as one over-long prompt.
- Done: `query_prefix` on an embedding model, before questions only.
- Qwen3-Embedding-4B on the RTX 6000 (2026-10-09): llama.cpp Q8 1,575
tok/s as first set up (32k cache, 16 slots), 2,700 with a 16k cache,
FlashAttention and ubatch 1–2k; f16 no better. vLLM fp16 (`--runner
pooling`) 6,200 direct, 4,700–4,900 through the gateway in the import,
and its vectors match llama.cpp's (cosine 0.9995). The 103,579 chunks
took 3 h. Done (2026-10-10, branch `admission-bulk`): a source per
profile, so an embedding model's GPU profile runs vLLM and its CPU
profile llama.cpp; a band's own `queue_ttl` for bulk imports, and
`Retry-After` on a busy refusal, which is what had turned passages away
(llmgw-kb retries only what says when to).
- Retrieval on 40 questions written from the corpus, document in the top
5: bge-m3 31/40 (Turkish questions 13/21), Qwen3-Embedding-4B 37/40
(18/21), with its query prefix 36/40 and first place 31/40 instead of
28 (MRR 0.738 → 0.789 → 0.838). Next: translating the question with the
chat model, and a reranker.
## G. Jobs: 3D generation through ComfyUI (2026-10-10)
A request for a 3D model takes minutes on the one 24 GB card, and the card has to be
emptied of the chat model first. That is not a request to hold a socket for
— `internal/router/activate.go:46` already says so — it is a job: queued,
answered with an id, asked after, its result downloaded. The job machinery
is built first and tested without a GPU; the ComfyUI generalisation and the
custom-node install come after. Decided 2026-10-10: a `jobs` table of its
own rather than a one-line batch (the JSONL shape would be artificial and
has nowhere for progress), and progress is shown, not just a status.
Which models (decided 2026-10-10): the assets go into a game sold on
Steam, worldwide, the EU included, so the licence of the output decides
before the quality does. Hunyuan3D (every version) is out: Tencent's
licence excludes the EU, UK and South Korea, and whether a game shipped
there with its outputs is "use in the Territory" is not a question to
leave to a court. In, in this order: **TRELLIS.2** shape (MIT; the best
geometry; its own texture baking goes through nvdiffrec and nvdiffrast,
both under NVIDIA's non-commercial source licence, so that stage is not
run), **Step1X-3D** (Apache 2.0, StepFun; shape and texture in one, the
EU-safe textured path — its ComfyUI node and VRAM need are to be
checked), **Direct3D-S2** (MIT, DreamTech; high-detail shape, has a
ComfyUI node) if TRELLIS.2's detail falls short. Not in: TripoSR and
InstantMesh (permissive but superseded), Stable Fast 3D (Stability's
community licence, revenue-capped; served all the same since 2026-10-10
at the user's request, see G3), SAM 3D Objects (Meta's own licence,
to be read before it is considered). Steam's disclosure form (changed
2026-01-16) lists pre-generated 3D models as content that must be
declared on the store page: the licence notice G3 writes into the GLB is
what the studio answers that form from.
### G1. Jobs: store, worker, endpoints (M) — done 2026-10-10 (branch `jobs-g1`)
Built as written, with two choices: a job found running after its gateway
died is run again from the start (the prompt id column is there for G2 to
follow the same work instead), and the request is validated at the door
only as far as costs nothing — key, model, allowlist, the request's shape
— with limits, guardrails and admission applied when the worker replays it,
said as the job's error. The result file's `content_type` is the job's; the
files endpoint still serves every file as an octet stream.
- Store: `jobs` (id, owner key/principal, kind, model, status, input
(JSON), progress (JSON: queue position, percent, step), result file id,
error, created/started/finished, lease owner/until), migrations for
sqlite and postgres beside `internal/store/batches.go`, whose
claim/renew/release lease pattern is copied, not shared: a job is one
unit of work, a batch is many lines.
- Worker: `internal/router/jobworker.go` after `batchworker.go`. Any
gateway on the store claims a queued job, asks for the model with
`activator.Want` and waits as long as it takes (no `ActivationWait`
bound: nobody is holding a connection), runs it, stores the output
through the files store, writes usage and price, marks it done. A
gateway that dies mid-job loses its lease and another one picks it up;
the ComfyUI prompt id is in the job row so the second gateway asks
after the same work rather than queueing it again.
- Endpoints: `POST /v1/3d/generations` validates like any inference
request (key, allowlist, limits, admission, guardrails on the prompt),
writes the job, answers 202 with `{id, status: "queued"}`;
`GET /v1/3d/generations/{id}` returns status, progress and, when done,
`output_file_id` and the usage; `POST .../{id}/cancel`; the file comes
from `GET /v1/files/{id}/content`. Owner-scoped like batches. Results
are kept for the batch files' retention and deleted with them: a
departure from `images.go`'s "kept nowhere", because a mesh is a
download, not a JSON field; the retention is the bound.
- Done when: a job survives the gateway that took it being killed, a
cancelled job leaves ComfyUI's queue (`comfy.Client.cancel`), two
gateways never both run one job (test with the lease), and the usage
row carries the job's price.
### G2. Progress from ComfyUI (S, after G1) — done 2026-10-10 (branch `jobs-3d`)
Built as written: the gate's websocket under its own client id, the
client_id of every /prompt rewritten, /progress/{prompt_id} on the gate,
the router reading it and /queue into the job (only into a job of the same
key). Left: a node that reports no steps (TripoSR's) shows its name and no
percent; a vanished replica is said by the job failing, not by progress.
The gate (`internal/comfy/gate.go`) passes seven paths and no websocket.
Rather than open `/ws`, the gate subscribes to ComfyUI's own `/ws` once,
with `golang.org/x/net/websocket` (already a dependency), under a client
id of its own, and rewrites the `client_id` of every `/prompt` it
forwards to that one. It keeps the last `executing`, `progress`
(value/max/node) and `execution_error` message per prompt id and serves
them at `GET /progress/{prompt_id}` on the gate; the router polls that
beside `/history` and `/queue` and writes queue position, percent and the
current node's class into the job's progress. The gate's buffer is
bounded (the last N prompts) and the websocket reconnects. Done when a
3D job shows "queued, 2 ahead" then "running 40%, step 12/30" in
`ctl jobs` and on the account page, and a job whose replica vanished
says so within one poll.
### G3. ComfyUI beyond pictures: 3D models and custom nodes (M, after G1) — done 2026-10-10 (branch `jobs-3d`), with TripoSR
Built: output kinds, image upload through the gate, every output list
fetched, OBJ to GLB, licence in /v1/models, the job and the GLB, per_mesh
and usage.meshes (migration 0045), custom nodes cloned at their commit by
the gate with packages beside the replica (a node's named packages at its
range, the rest at ComfyUI's versions). Not as written: the model. On the
PoC's Turing card TRELLIS.2 cannot run — it needs Meta's gated DINOv3,
its published background remover (RMBG-2.0) is non-commercial, and its
sparse attention and Direct3D-S2's need flash-attention (Ampere and
newer). TripoSR (MIT) proves the chain on cuda01: a .glb from a picture
in about 30 s. Left: background removal before TripoSR (BiRefNet, MIT,
as a node), TRELLIS.2 or Direct3D-S2 on an Ampere card with an ungated
encoder, a missing node refusing the replica by name.
Added 2026-10-10 at the user's request, beside the order above: **Stable
Fast 3D** as `sf3d` (Stability AI Community License: free under US$1 M
annual revenue, an enterprise licence above, "Powered by Stability AI"),
the textured mesh that runs on Turing: about 1 s a mesh warm in fp16,
UV-mapped GLB with its texture, 18 GB of the card at peak. Its weights are
gated, so they were fetched once with the user's token into
/srv/llmgw-comfy/stable-fast-3d and linked into the engine user's
Hugging Face cache, which its loader node reads by repository name; no
token is on the machine at runtime. Its own save node returns the GLB as
base64, which the gate cannot fetch, so `LLMGWSaveMesh` writes the file;
`LLMGWPrepareForMesh` now also gives the object's mask. Left: its two
CUDA extensions (texture_baker, uv_unwrapper) are not on PyPI, so they
were built on cuda01 and installed into the engine's venv by hand; a
custom node's requirements need a way to name a local build, or the
engine install must carry them, before a customer site gets this. And
rembg's default session now fetches BRIA RMBG-2.0 (non-commercial):
every workflow must name its rembg model (ours say u2net).
- Catalog: a model makes `pictures` or `meshes` (`MakesImages` becomes an
output kind; `ServesComfyUI` stays). 3D weight folders in the gate's
`modelFolders`; the workflow's placeholders gain `image` (the input
picture, base64 in the request, written to the replica's `input/` by
the gate through a new `POST /upload/image` the gate allows — or a
base64-loading node, whichever TRELLIS.2's wrapper wants).
- `comfy.Client.fetch` reads every output key, not `images` only, and
fetches each file named by `/view`; `Image` becomes `Artifact` with its
content type (model/gltf-binary, application/octet-stream for .obj).
- Custom nodes: a model (or the engine config) names git repositories
and a pip requirements list; the agent's provision step clones them
into the replica's `custom_nodes/` (the gate's `--base-directory` is
where ComfyUI looks, not the install directory) and installs the
requirements into the engine's venv with the same PyTorch index and
lock discipline as A8. A replica with a missing node refuses to start
with the node's name in the error rather than ComfyUI's traceback.
- Licence of the output (decided 2026-10-10: it matters). A catalog model
carries `license: {name, url, notice}`; a job's answer, `/v1/models`
and the portal page show it beside the result, and the mesh's GLB
`asset.extras` carries the notice too, since the file travels without
the API. What was checked on 2026-10-10: TRELLIS.2 weights are MIT and
its outputs free, but its texture baking depends on nvdiffrast, whose
NVIDIA Source Code License is non-commercial — a commercial service
must render textures another way or skip that stage. Hunyuan3D 2.0 and
2.1 claim no rights in outputs, but the licence excludes the EU, UK and
South Korea, needs Tencent's permission above 1 M monthly active users,
forbids using outputs to train other models, and asks for "Powered by
Tencent Hunyuan"; the notice ships with any distribution. TripoSR is
MIT, InstantMesh Apache 2.0. Every one of them trained on Objaverse,
some of whose objects are CC-BY-NC: a provenance question no licence
text settles, to be said in the notice rather than hidden.
- Pricing: `per_image` stays; `per_mesh` beside it in `accounting.Price`,
`Outcome.Meshes`, the usage sums and exports (as eaea671 did for
pictures).
- Done when: TRELLIS.2 on cuda01 with `scaling: {min: 0,
idle_timeout: 10m}` makes a .glb from a picture through G1's endpoint
with nvdiffrast and nvdiffrec not installed in its venv (the licence
is kept by the install, not by a note), the GLB carries the MIT
notice,
the card is free again after the idle timeout, and the same request
against flux-schnell is refused as "makes pictures, not meshes".
### G4. Portal and console (S, after G2) — done 2026-10-10 (branch `jobs-3d`)
Built: /3d with model-viewer served from the gateway, progress, download
and licence; `ctl 3d list|get|cancel` over /api/v1/client-jobs (ctl jobs
was taken by the control plane's own work). Left: the console's Jobs view.
A 3D page beside `/images` (upload a picture, watch progress, download
the .glb, a viewer with `<model-viewer>` from the allowed CDNs), `ctl
jobs list|get|cancel`, the console's Jobs view. The page sends down the
same path as the API, like `imagesSend` does.
## H. ComfyUI as a platform (written 2026-10-11)
G made one model at a time work: flux for pictures, TripoSR and SF3D for
meshes, each with its own endpoint, its own request shape and its own
replica. The user's direction (2026-10-11): llmgw is a generic platform,
and should serve whatever ComfyUI can run — pictures, edits, video,
audio, meshes, upscaling, segmentation — as data in the catalog rather
than code per model. Two decisions shape everything below:
- **The licence is metadata, not a filter.** llmgw does not leave a
model out because of its licence. The licence travels with the model
and with every file it makes; what a site will not serve is that
site's policy (H6). The game studio's EU constraint is one such policy,
not a decision the code makes for everyone.
- **The install fits the hardware.** The PoC has one Turing card; other
sites will have Ampere, Ada and Hopper. A catalog entry must be
writable once and placed sensibly anywhere: fp16 on Turing, bf16 or
fp8 where the card has them, flash-attention models only where it
runs, CUDA extensions built for the card that runs them (H2, H4).
The first set of models proves the structure at its corners rather than
by licence: Qwen-Image-Edit (several weight files, two pictures in),
Wan 2.2 small (video out, a long job), ACE-Step (audio out), SF3D (a
package not on PyPI, gated weights), Hunyuan3D (a licence that excludes
the EU, which H6 must be able to say no to).
### H1. A workflow says what it takes and makes (M) — built 2026-10-11, not yet tried on the PoC
Built as written, with three choices: a run answers with one file, the
first of its output kind (several outputs as one zip is left); the
workflow's placeholders are checked against the inputs when a run is
served, since the catalog never reads the workflow file; and video,
audio and files count as nothing in usage until a per-run price exists
(per_image and per_mesh still count pictures and meshes).
- Catalog: `comfyui.inputs` — a list of `{name, type, required, default,
min, max, choices, max_mb, doc}`, type one of text, int, float, bool,
choice, image, mask, audio, video, file. Each is a placeholder of the
same name in the workflow. The template's own placeholders are checked
against the list when the catalog is built: one the workflow uses that
no input or built-in names is refused there, not at the first request.
- `comfyui.output` gains `video`, `audio` and `files` beside `pictures`
and `meshes`; `files` takes whatever the workflow saves. `comfy.Image`
becomes `comfy.File` and `typeByName` knows mp4, webm, gif, wav, flac,
mp3, ogg.
- Endpoint: `POST /v1/workflows/runs` with `{model, inputs: {...}}`, a
job like G1's (`GET /v1/workflows/runs[/{id}]`, `.../cancel`). A file
input is base64, a data URL, or a `file-…` id from `/v1/files` for
what is too big to send inline (video, long audio). Files go into the
replica's input directory through the gate's `/upload/image`, which
ComfyUI uses for any file. `/v1/images/generations` and
`/v1/3d/generations` stay as they are, as fixed shapes over the same
machinery.
- The models list (`/v1/models`) gives each ComfyUI model its inputs and
output kind, so a client can build a form without reading the catalog.
- Done when: the existing flux, triposr and sf3d entries work unchanged,
and one model with a picture and a text input (Qwen-Image-Edit) runs
through `/v1/workflows/runs` with a 400 for a missing required input
before any job is written.
### H2. Profiles that fit the hardware (M) — built 2026-10-11
Built as written. A profile by need is left out of placement until the
cluster's cards are known: with no class, placement would have read it as
a CPU profile. A profile's own `source` is loaded under its own file name
by the workflow's `{{checkpoint}}`.
- A profile may say `gpu: {min_compute_capability, min_memory_gb}` in
place of `gpu_class`. When the reconciler places a model, such a
profile stands for every GPU class in the cluster that meets it, at
the profile's priority: the catalog function that turns profiles into
placement's view takes the cluster's classes (class, compute
capability, memory) and returns one concrete profile per class that
fits, named `<profile>@<class>`. Placement itself is unchanged: it
still sees exact classes, and a tensor-parallel group still never
mixes them.
- A ComfyUI profile may carry its own `comfyui` block (workflow, nodes,
checkpoint) over the model's: the fp8 workflow on compute 8.9 and up,
the fp16 one on 7.5. A Turing card is not an error, it is the profile
that fits it.
- Done when: one catalog entry with an "ampere+" profile (min 8.0) and a
"turing" fallback places the fallback on cuda01, and the same entry,
in a test with an A100 in the inventory, places the other.
### H3. Environments: which models can share a replica (S, the catalog side)
- `comfyui.environment: <name>` puts a model in a named environment.
Models in one environment must agree on every custom node they both
name (same repository, same commit) and their requirements must
resolve together; the catalog refuses an environment that cannot, with
both models' names. Models with no environment are each their own, as
today.
- `Catalog.Environments()` returns each environment with its models and
the union of their nodes: what one replica of it must install.
- Placement and eviction of a replica that serves every model of its
environment (so flux, SF3D and Qwen-Image-Edit stop handing the card to
each other with a 30 s cold start each time) is the other session's
work (llmgw-b7), built on this.
### H4. Custom nodes with packages that are built, not downloaded (S) — built 2026-10-11
Built as written, with `uv build --no-build-isolation` against ComfyUI's
Python, the card's capability asked of torch in the replica (so
CUDA_VISIBLE_DEVICES is the card it will run on), and wheels kept under
the engines' cache by commit, `sm<arch>` and directory. Also
`comfyui.huggingface_repo`: a node that loads its weights by repository
name (SF3D's) finds them in the engines' Hugging Face cache, linked by the
gate, so no token is on the node.
- `nodes[].build: [subdir, ...]`: directories of the node's repository
that are Python packages with C++/CUDA extensions (SF3D's texture_baker
and uv_unwrapper). The gate builds each as a wheel with the engine's
Python, `TORCH_CUDA_ARCH_LIST` set from the compute capability of the
card it runs on, and installs it into the replica's own `site` like
any other requirement. Built wheels are kept under the engine's home by
node commit, subdirectory and architecture, so the second replica on
the same kind of card does not build again.
- A node needing nvcc on a node without it refuses the replica with that
said, not with a compiler's traceback.
- Done when: SF3D runs on cuda01 with nothing installed into the engine's
venv by hand (the hand install of 2026-10-10 removed first).
### H5. Licence on every output (S) — done 2026-10-14: the whole licence in GLB asset.extras and PNG iTXt; video and audio not yet
- `License` gains `id` (SPDX where there is one, else a lowercase name:
stability-community, tencent-hunyuan-community), `commercial` (unset is
not said), `excluded_regions` (ISO 3166 codes, `EU` for the union),
`revenue_cap_usd` and `attribution` ("Powered by Stability AI"). All
optional but the name. Done 2026-10-11 in the catalog, so H6 can match
on `id`.
- Written into the file where the format has a place for it: glTF
`asset.extras.license` (as now), PNG an `iTXt` chunk named `license`
(the workflow's own text chunks are still stripped), MP4/WebM and the
audio formats in their metadata where ffmpeg is at hand on the router,
otherwise beside it in the job's answer only — said in the docs.
### H6. Licence choices (S) — done 2026-10-11 (4bbac08), live on the PoC
The user asked (2026-10-11) for the choice to be a person's: on their
profile they pick the licences they will not use, and their keys and
portal session neither see those models in `/v1/models` nor may call
them (403, saying which licence). Matched on `license.id`, and on
`commercial` / `excluded_regions` where a choice is put that way. Its
store table is migration 0046. A site-wide or team-wide default can sit
on top of it later.
### H7. A job worker per model, not one for all (S) — done 2026-10-14: one job per model at a time, eight in all
The worker runs one job at a time: a job waiting for the card holds up a
job for another model that could run now (seen on the PoC, 2026-10-10).
Jobs are claimed and run concurrently up to a limit per model (or per
environment, after H3) and a cluster-wide cap, with the lease and
leader-only rules of G1 kept.
### H8. Presets that add themselves (S) — done 2026-10-13 (v0.14.5)
flux-schnell and triposr come with llmgw (`ctl model add <preset>`), and
the leader adds them on demand where a node fits one, the cluster installs
ComfyUI and the catalog makes nothing of that kind (`presets.auto`); a
preset removed is declined and not added back. The cluster page and the
console show and add them.
### H9. Small things learned on the PoC (2026-10-14)
- Done: `albedo_match` on sf3d (its delighting made dark objects light);
`on_demand.evict_after_idle` / `min_lifetime` as live settings; an
upgrade that leaves nodes behind says which; `ctl model serve` serves an
embedding model for embedding; refreshes wait while a form is filled in.
- Open: llmgw's `/mcp` with picture, 3D, VLM and workflow tools, so a
client needs no server of its own (asked by the game team); the shared
ComfyUI replica (H3's placement side).
## D. Facts worth knowing before starting
- Admin API: `127.0.0.1:9090`, no auth, `ctlClient` in `internal/cli/ctl.go`.

## Unreleased
### Added
- **Pictures uploaded to work from**: `/v1/files` takes `purpose=vision` or
`user_data` besides `batch`, kept as long as job results, so a picture is
sent once and named by its `file-…` id in the MCP tools and a workflow's
inputs.
- **One ComfyUI for an environment's models**: ComfyUI models in one
`comfyui.environment` (two or more) share one replica — the catalog
makes it a hidden entry, `comfyui-env-<name>`, on the first member's
profiles with the most memory any member needs, carrying every member's
weights and custom nodes. Asking for any member starts it; it answers for
each with that member's workflow and checkpoint, and the members get no
replicas of their own. A picture model and a 3D model on one card stop
handing it to each other with a cold start each way.
- **Pictures, 3D models, vision and workflows as MCP tools** at `/mcp`,
beside the memory notes, each offered only where the gateway has a model
for it: `generate_image` (with `concept`, `side` and `texture` styles),
`generate_mesh` (from a picture or a prompt), `review_images` (a vision
model, to a JSON schema), `run_workflow`, `job_status` and
`gateway_status`. Each makes its request under the caller's key, so
allowlists, limits, licences and budgets apply and it is charged like
any request; what it makes is kept as the caller's file and answered by
id and download URL. A client that takes a stream gets
`notifications/progress` while a mesh is made and waits up to ten
minutes; one that does not, 50 seconds, then the job id.
- **Setup asks where alerts go**: `llmgw server init --webhook URL`
(repeatable) and a **Notification webhooks** field on both setup screens.
Slack's, Mattermost's and Rocket.Chat's addresses are sent Slack's text,
any other the event as JSON (`slack:` or `json:` in front says which).
They are added to the cluster's `notify.webhooks` beside those already
there, and each is sent a test once the control plane runs on them.
- **Extended thinking on `/v1/messages`**: `thinking: {type: "enabled"}`
tells a model that thinks by its chat template to (`enable_thinking`),
and its reasoning comes back as `thinking` blocks before the text,
streamed as `thinking_delta` events; `disabled` tells it not to. Not
asked for, the reasoning is left out as before.
- **How long on-demand models hold a card** is a setting, in force on the
leader within seconds: `on_demand.evict_after_idle` (2m unless set) and
`on_demand.min_lifetime` (5m). On one card shared by a picture model and
a 3D model, 1m each brings the wait between a picture and its mesh to
about a minute.
### Fixed
- A model whose weights and context pool did not fit its card was added
and then failed to make its context on every start, taking the card from
others each time (Apertus 70B with a 65536-token pool, 8B with 131072, on
24 GB). `ctl model serve` shrinks the pool to what the card holds, saying
so, and refuses weights that do not fit at all; the portal's serve form
refuses such a pool and says the largest that fits.
- Removing weights from the mirror that a catalog model still loads is
refused, naming the model: removed from the mirror alone, the model stayed
in the catalog and its replicas went on loading the node's copy.
- Jobs ran one at a time, so a 3D job waiting for the card held up another
model's job that could have run. They run side by side, one per model at
a time and eight in all, on the leader as before.
- `llmgw ctl model serve` served an embedding model as a chat model: no
`--embedding`, four slots, a 512-token batch, `embeddings` unset and a
"say hello" smoke test it could not pass. A model whose GGUF says it
pools (or `--embeddings`) is served for embedding: 32 slots of 1024
tokens unless sized otherwise, a batch that holds a whole passage, and
one vector asked for as its smoke test.
- `llmgw ctl upgrade` checks every node's version once the waves are done
and fails naming any not on the release, and says when the control plane
has no nodes registered; `llmgw upgrade` on a control plane says how many
nodes it left behind and the command that upgrades them. A site's nodes
stayed a release behind with nothing to say so.
- The cluster and node pages swapped their live part every few seconds,
forms and all, so filling one in raced the clock: what was typed, an
open choice and the focus were lost. The refresh now waits while a field
in it has the focus or a form in it has been typed into and not sent;
the mirror page's reload during a download waits the same way.
## v0.14.5 — 2026-10-14
Picture and 3D models that add themselves where a card fits them, with a
card on the portal and a screen in the console to see and add them; a
mesh's colour brought to the picture it was made from; and the whole
licence written into every mesh.
**Upgrading.**
- The store gains a table (migration 0047: preset_state); nothing to do.
- **`presets.auto` is on**: once upgraded, the leading control plane adds
flux-schnell and triposr, on demand, where a node's card fits one, the
cluster installs ComfyUI (`engines.comfyui`) and the catalog makes
nothing of that kind. Nothing is fetched until somebody asks for one.
Turn it off with `llmgw ctl model presets auto off`.
- **Nodes** need this release for `albedo_match` (it is in the save node
the gate puts in each replica); a ComfyUI replica takes it when it
starts again.
### Added
- **A mesh's base colour brought to its picture's**: `LLMGWSaveMesh` takes
`albedo_match` with the picture and its mask, and scales the texture in
linear light to the object's brightness in the picture. Stable Fast 3D
takes the light out of what it sees and read a dark basalt (0.17) as a
light stone dimly lit (0.67); matched, it is 0.17. On sf3d it is the
`albedo_match` input (off unless asked).
- **Picture and 3D models by themselves**: once a node has a card that fits
flux-schnell or triposr and the catalog makes nothing of that kind, the
leading control plane adds the preset on demand — so a new cluster's
portal has its Images and 3D pages without a definition written — where
the cluster installs ComfyUI. `presets.auto` turns it off; a preset
somebody removes is not added back. `GET /api/v1/presets` says how each
stands and why one is not added; `POST /api/v1/presets/{name}` adds one
(and sets `engines.comfyui` if the cluster has none); `PUT
/api/v1/presets/auto`. Each automatic addition is in the audit log.
- **Presets on the portal and in the console**: the cluster page's
**Pictures and 3D models** card lists each preset — what it makes, the
classes it fits here, whether and by whom it was added, why the leader
has not — with an **Add** button that says first when it would install
ComfyUI and restart the control planes, and the switch for `presets.auto`.
The console's models screen shows the same; **A** adds one, **P** flips
the switch. `ctl model add PRESET` and `ctl model presets` go through the
API (and `ctl model presets auto on|off`), falling back to the entry as
v0.14.4 sent it on an older control plane.
### Fixed
- A mesh carried only its licence's name, URL and notice; it carries the
whole licence as `/v1/models` gives it — id, commercial use, excluded
regions, revenue cap, attribution — for a pipeline that sorts assets by
licence.
- A workflow's `{{name|false}}` default filled a BOOLEAN input with the
word rather than a boolean.
## v0.14.4 — 2026-10-13
Any ComfyUI workflow as a job, with typed inputs; picture and 3D models
added by name; profiles that fit whatever card a site has, and ComfyUI on
a V100; licences a machine can match and a person can leave out; a job
waiting for the one card says what holds it. Many fixes to on-demand
models taking turns on one card.
**Upgrading.**
- The store gains a table (migration 0046: user_excluded_licences);
nothing to do.
- **Nodes** need this release for ComfyUI on Volta or Pascal cards (the
cu126 build), for a driver from NVIDIA's open kernel module to be read,
and for a node that loads its weights by repository name (sf3d); a
ComfyUI already installed is kept.
- **Control planes before nodes**: an entry using the built-in `triposr`
workflow, or a `gpu:` need instead of a class, is refused by an older
control plane.
- Models added with `llmgw ctl model add <preset>` take the preset's name;
remove an entry of that name first.
### Added
- **The client API described**: OpenAPI 3.1 at `/v1/openapi.json`, no key
needed, generated from a route table a test holds to the router's own;
and `/docs/api`, Swagger UI (served from the gateway) over it and, for
staff, over the admin API's document.
- **A job waiting for the card says so**: `progress` is
`{"state":"waiting_gpu","held_by":…,"eta_seconds":…}` while another
on-demand model holds it; a direct request's 503 carries
`X-Llmgw-Waiting-For` and `X-Llmgw-Eta-Seconds`.
- **Any ComfyUI workflow, as a job**: `POST /v1/workflows/runs` with
`{model, inputs}`. A model's catalog entry declares its inputs
(`comfyui.inputs`: text, int, float, bool, choice, image, mask, audio,
video, file, with bounds and defaults) and its output (`comfyui.output`:
pictures, meshes, video, audio or files); a request is checked against
them before a job is written, file inputs are base64, a data URL or a
`/v1/files` id, and `/v1/models` lists each model's `workflow` so a
client can build its form. A PNG result carries the licence in an
`iTXt` chunk, a GLB in `asset.extras` as before.
- **Environments**: `comfyui.environment` names ComfyUI models that agree
on their custom nodes and may share one replica; the catalog refuses
one that cannot.
- **Profiles that fit the hardware**: a profile may say `gpu:
{min_compute_capability, min_memory_gb}` instead of `gpu_class`, and
stands for every class in the cluster that meets it, as
`<profile>@<class>`; a ComfyUI profile may carry its own `comfyui`
workflow, checkpoint and nodes, and any profile its own `source`. One
catalog entry then runs fp8 where the card has it and fp16 on Turing.
- **Custom nodes that compile**: `nodes[].build` names directories of a
node that are C++/CUDA packages; the gate builds each as a wheel for the
card the replica runs on, keeps it on the node, and installs it beside
the replica. `comfyui.huggingface_repo` shows a model's weights to a node
that loads them by repository name.
- **A licence a machine can match**: `license.id`, `commercial`,
`excluded_regions`, `revenue_cap_usd`, `attribution`.
- **On-demand models in `/v1/models`**, with `loaded` saying whether one is
up now; a picture is cut out and put on grey before TripoSR sees it
(`LLMGWPrepareForMesh`, rembg when it has no alpha).
- **Licences a person leaves out**: on the profile page, by licence, or by
rule — every licence forbidding commercial use, every licence granting
nothing in a region — so a model under one is neither listed to nor
served for that person's keys and sessions (403 `licence_excluded`).
- **Presets: a picture or 3D model added by name.** `llmgw ctl model add
flux-schnell` or `triposr` adds an entry that comes with llmgw — its
workflow (TripoSR's now built in), custom nodes, packages and licence,
and a profile by card need rather than class — and has the nodes install
ComfyUI when the cluster's settings name none. `llmgw ctl model presets`
lists them; the console's **A** on the models screen offers them beside
a definition file.
### Fixed
- A model waiting for another on-demand model to give up the card failed at
once as "cannot be placed"; it now waits, and a job with it.
- A model evicted for being idle was placed again on the next pass, ahead of
the one it made room for.
- A job or batch leased by a standby control plane, whose router has no
endpoints, waited on "loading" for good; they are served only by the
leader. A job told its model fits nowhere asks again for five minutes
before failing, which an agent re-registering makes true for seconds.
- An on-demand replica adopted after a restart was never idle enough to
evict, so a model waiting for its card waited out its whole idle timeout;
it counts as used at adoption.
- A picture in a prompt was counted as its base64 by the context check, so
one 1280x720 PNG was "138 thousand tokens" and a vision model refused it;
a picture or a sound now counts as about a thousand.
- An on-demand model of a higher class was evicted, idle, for a lower-class
one two minutes into a lull; it keeps the card through its idle timeout,
and a model waiting on it is told so.
- A model removed from the catalog stayed wanted, so added again it loaded
unasked.
- A node that loads its weights by repository name (sf3d) went to Hugging
Face for a gated repository and got a 401: the agent did not hand the
gate `comfyui.huggingface_repo`, so the weights on the node were never
linked into its cache.
- **ComfyUI on a V100.** torch's CUDA 12.8 and newer builds have no Volta
kernels, but its cu129 build was taken to run from compute capability
7.0, so on a V100 both ComfyUI builds were installed, about 10 GB each,
and failed with "no kernel image". Cards older than Turing now get
ComfyUI on PyTorch's CUDA 12.6 torch (build `cu126`); a Turing or newer
node keeps the build it has.
- **The open NVIDIA driver read by its version.** With the open kernel
module, the default since 560, the agent read the driver as "for" and so
as unknown, and tried every engine build whatever driver it needs.
## v0.14.3 — 2026-10-10
3D models from a picture, as jobs: made by ComfyUI on the cluster's cards,
with their progress, their licence written into the mesh, a price per mesh
and a page to make them. Also: a profile's own weights, a band for bulk
work, and fixes for control planes behind a balancer and agents that
restart.
**Upgrading.**
- The store gains tables and columns (migrations 0043–0045: notify_sent,
jobs, usage meshes); nothing to do.
- **Nodes** need this release for their engines' output to survive an
agent restart and for ComfyUI's custom nodes and progress; engines
started by an older agent keep its pipe until they are restarted.
- A 3D model needs a model that makes them (see install.md, "A model that
makes them"); none is added.
### Added
- **Jobs: 3D models asked after, not waited for.** `POST
/v1/3d/generations` answers 202 with a job id; `GET
/v1/3d/generations/{id}` says its status, progress and, when done, the
file its result is in (`/v1/files/{id}/content`); `POST .../cancel` stops
it, in the engine's queue too. The request is replayed by whichever
gateway holds the job's lease through the same path a client's request
takes — key, allowlist, limits, admission, guardrails, accounting — so
it is charged like any request, tagged `job=<id>`, and a model still
loading is waited out for as long as the job has (24 h) rather than
refused. A job survives the gateway that took it; results are kept for
`router.batch.retain_days`. Migration 0044.
- **ComfyUI models that make meshes** (`comfyui.output: meshes`). The
picture is uploaded to the replica's ComfyUI and the workflow's
`{{image}}`; the mesh the workflow saves is the job's file, an OBJ turned
into a GLB. TripoSR (MIT) is the tested model; on Ampere and newer cards
stronger ones can be added the same way.
- **Custom nodes** (`comfyui.nodes`): a repository at a full commit, put in
each replica's own `custom_nodes` by the gate, with its packages
installed beside the replica, never into ComfyUI's environment.
- **A job's progress**: the gate listens to ComfyUI's websocket and the job
says queued and how many ahead, then the node running, its step and
percent.
- **A model's `license`** (name, url, notice), in `/v1/models`, in the job,
on the portal and in the GLB's `asset.extras`.
- **`per_mesh`** in `auth.pricing`; usage rows, sums and exports count
`meshes`.
- **`/3d` on the portal**, beside `/images`: a picture chosen, the job
followed, the mesh in a viewer with a download and its licence; and
**`llmgw ctl 3d list|get|cancel`** for every owner's jobs.
- **A profile's own `source`**: the weights it loads instead of the
model's, so an embedding model can run on vLLM from its repository on a
card and on llama.cpp from a GGUF on CPUs as one model. Placement prefers
nodes holding each profile's weights, `ctl model add` checks every
source, and `ctl weights` collects none a profile loads.
- **A band's own `queue_ttl`** (`router.admission.bands[].queue_ttl`): how
long its requests may wait for room, instead of the admission's 30 s. A
band for bulk work — a knowledge-base import — waits behind people rather
than being turned away.
### Fixed
- **An engine's output no longer breaks when its agent restarts.** Engines
wrote to a pipe of the agent's, which an agent that restarted and adopted
them left with no reader; an engine's next large write failed, and in a
Python engine took the request it was reporting on with it. Each process
now writes to its own file in the agent's work directory, and an adopted
engine's log keeps what it wrote before the restart.
- **Single sign-on behind a balancer.** The cookie that carries a sign-in
across the identity provider was signed with a key of each process's own,
so with two control planes a callback that reached the other one was
refused. The key is now a secret in the store, the same on every control
plane.
- **Notifications sent once by two control planes.** Each kept its own
hour of quiet per event, so a budget spent on a team both served was
announced twice. The control plane that claims an event in the store
(migration 0043) sends it; with the store unreachable it is sent anyway.
- **A request turned away for a busy cluster says when to come back.** A
request that waited as long as it may (504) or found the queue full (503)
had no `Retry-After`, so `llmgw-kb` counted the passage as failed instead
of sending it again; both now say 10 seconds.
- The usage sums and exports count pictures (`images`), as the request
records did; pictures made before are added to the sums.
## v0.14.2 — 2026-10-10
Pictures: OpenAI's `/v1/images/generations`, made by ComfyUI on the
cluster's own cards. The agents install ComfyUI themselves, the gateway
prices pictures by the picture, and the portal has a page to make them.
Also: on-demand models that survive a failover, and knowledge-base
embeddings fixes.
**Upgrading.**
- The store gains a column (`usage.images`); nothing to do.
- **ComfyUI is installed only where asked**: `llmgw ctl config set
engines.comfyui 0.39.2` has every node with an NVIDIA GPU build it (about
10 GB under `/opt/llmgw/engines`). Nodes need this release to install it
or run engine `comfyui`.
### Added
- **Pictures at `/v1/images/generations`**, OpenAI's shape, through the same
key, allowlist, limit, admission and guardrail checks as any request. A
model with profiles on engine `comfyui` is placed on a GPU node like any
other. A ComfyUI server outside the cluster can be an external model with
`api: comfyui` instead. The workflow is a built-in (`flux-schnell`, the
default, or `flux-dev`) or a JSON file in ComfyUI's API format, with
`{{prompt}}`, `{{width}}`, `{{seed}}` and the like where the request's
values go. Requests may also send `seed`, `steps`, `negative_prompt` and
`guidance`. The seed used comes back in `x-llmgw-seed`. Pictures come back
as `b64_json`; ComfyUI's workflow is stripped from each PNG, and a client
that leaves takes its workflow off the queue. `/v1/models` says `images`
for such a model.
- **Engine `comfyui`.** ComfyUI asks for no key, so the agent starts it
behind `llmgw comfyui-gate`. ComfyUI listens on the loopback only. The
gate listens on the replica's port, demands the replica's key, and lets
through only what the router asks. The model's `comfyui:` block names
the workflow and, for a source that is a set of files, the checkpoint.
- **The agents install ComfyUI** (`engines.comfyui`). The release's source is
checked against a digest llmgw holds, since GitHub publishes none, and a
version without one is refused. Its requirements are resolved as PyPI
stood the day after the release, with PyPI's CUDA 13 torch or PyTorch's
CUDA 12.9 one for an older driver, and the result is checked on the card.
A ComfyUI installed by hand is named by `engines.comfyui.dir` in
agent.yaml.
- **A price per picture**: `per_image` in `auth.pricing`, on top of the
prompt's tokens. A model priced only per picture is not free, so a spent
budget still stops it. Each usage row keeps how many pictures were made,
shown by `llmgw ctl request`.
- **`/images` on the portal**, beside the chat, for the models that make
pictures. The chat no longer offers them. The page offers size, how many,
seed, steps and a negative prompt, and shows each picture with its seed
and a download link. Nothing is kept but the usage.
- **An embedding model's `query_prefix`**, put before the question a
knowledge-base search embeds and never before documents, for Qwen3-Embedding
and models trained like it.
### Fixed
- **An awake on-demand model survived no restart or change of leader of the
control plane.** A control plane that had heard no requests read every
on-demand replica its nodes reported as wanted by nobody, and drained them
all. An adopted replica now gets a whole idle timeout.
- `ctl models` said `not placed` for an on-demand model that had been woken
and was serving; it now says `ready (on demand)`.
- A batch of embeddings was refused as one over-long prompt when the
passages together exceeded the context, though each one fit. The longest
input is what has to fit.
- The chat's kept conversation sat in the browser under one key for
everybody, so the next person to sign in on the same browser opened the
last one's conversation. It is kept per account, and signing out clears
what the pages stored.
## v0.14.1 — 2026-10-09
Adapters trained on the nodes from a knowledge base and kept private to
their owners; the cluster's and the agents' settings edited in one place;
the tenancy tree and keys over the admin API and in Terraform; knowledge
bases that hold up with many documents; the firewall setting on every
machine.
**Upgrading.**
- **Nodes** need this release to follow `agents.*` in the cluster's
settings; until a node is upgraded its agent.yaml is what it runs on.
- **A separate mirror machine and store members that run nothing else**
follow the firewall setting once what reads it is installed: run `sudo
llmgw mirror init` on the mirror again with the flags it was set up with,
and `llmgw server init --patroni` again for the store's members. A control
plane set up before v0.12.0 needs `sudo llmgw firewall sync --install`.
- **The store's PostgreSQL memory** applies after each member is restarted,
one at a time, the leader last; until then it runs as before.
- The store gains tables and columns; nothing to do. Existing knowledge-base
collections get their full-text index when a control plane starts, and
keep `vector` storage; only new collections use `halfvec`, and only on
pgvector 0.7 or later.
- Cached knowledge-base passages in vLLM are made again once, under the new
`cache_salt`.
### Added
- **The cluster's settings on the portal** (BACKLOG E4): `/admin/settings`
for administrators. It edits the document `llmgw ctl config edit` opens:
checked as a control plane would load it, refused when made from a
version since replaced, with the history to view and roll back. Changes
are audited by size, never by contents.
- **The nodes' agent settings in the cluster's settings** (BACKLOG E3):
`agents.default` and `agents.nodes.<id>` hold everything agent.yaml can
say but the agent's id, control planes, address and certificate. They are
sent to the agents as they change; an agent starts again on new settings,
or on an edited agent.yaml, with its engines serving throughout. Settings
that would not load are refused on save, and set aside on a node rather
than keep its agent from starting. Nodes need this release to follow
them.
- **LoRA adapters trained on the nodes** (BACKLOG F4): `llmgw ctl kb dataset`
writes question/answer pairs from a collection with a model of the
cluster. `llmgw ctl train start` trains an adapter on a node with its
installed vLLM's torch and a small overlay, on a card with enough memory
free (beside an engine, if it leaves that much), converting to GGUF for
llama.cpp. `llmgw ctl train publish` keeps it on the mirror (which now
accepts uploads) and makes it the model's adapter.
- **Adapters with owners.** An adapter's `owner` (org, team, project, user
or key) is the only part of the tree that sees it; to anyone else it is a
model that does not exist. An adapter trained on a knowledge base belongs
to a part of the tree that may read it, and is never made public.
- The knowledge bases' vLLM `cache_salt` follows the collections searched,
not the organization, so two teams of one organization no longer share
cached passages.
- **Organizations, teams, projects, API keys and memberships in the admin
API**: `/api/v1/orgs` (the tree), `POST /api/v1/teams` and `projects`,
`PATCH` to rename or move, `DELETE` for what is empty; `/api/v1/keys` to
issue (the key is in the answer, once), list and revoke; `/api/v1/users`
and `/api/v1/users/{id}/memberships`. They were only `llmgw org`, `keys`
and `users` on a control plane before. The Terraform provider manages them
as `llmgw_org`, `llmgw_team`, `llmgw_project`, `llmgw_key` (the key in a
sensitive `secret`) and `llmgw_membership`.
- **The firewall setting reaches every machine.** A separate mirror and the
store's members follow `firewall.enabled` and `firewall_networks` as nodes
and control planes did: the leading control plane tells the mirror over
its API, and keeps the state in the store for members that run no llmgw,
which a timer on each reads. The mirror also lets in the network of every
node the leader knows. `mirror init` and `server init --patroni` install
what follows it; run them again on a cluster set up before.
### Changed
- **The store's PostgreSQL is sized to its machine's memory.** Before, it ran
on PostgreSQL's defaults (128MB cache) under Patroni, or on 96MB on one
machine. Now each member gets a share of its own RAM, a smaller one where
a control plane or agent shares the machine, and the share is read again
every time `server init --patroni` runs. The new cache is applied by
restarting one member at a time, the leader last.
- **Knowledge-base searches hold up with many documents.** New collections
store their index as `halfvec` where pgvector is 0.7 or later (half the
memory, and embeddings up to 4000 dimensions instead of 2000); older
collections, and clusters on pgvector 0.6, keep `vector`. Each collection
has its own full-text index, as it has its own vector index, made for
existing collections when the control plane starts. The text arm ranks by
the cheap measure first and scores only those candidates.
### Fixed
- A knowledge-base search asking for more than 10 passages
(`X-Llmgw-Knowledge-K`) got at most 40 candidates per collection from the
vector index, whatever it asked for: pgvector's `hnsw.ef_search` is now
raised to the number wanted, up to 1000.
- `llmgw server backup` and `restore` against a replicated store over TLS
failed looking for `~/.postgresql/root.crt`: pg_dump was given
`sslmode=verify-full` without the cluster's authority.
## v0.14.0 — 2026-10-08
Knowledge bases: a company's documents, put in by people from their own
machines, kept apart per tenant, and answered from.
**Upgrading.**
- **pgvector on a cluster set up before this release.** Knowledge bases
need pgvector, which `server init` and the high-availability database
setup now install, but a rerun on a running cluster does not:
1. Install `postgresql-<version>-pgvector` on every database machine.
2. As postgres, run `CREATE EXTENSION vector` in llmgw's database.
3. Restart the control planes.
Until then everything else works, and `llmgw ctl kb list` says why
knowledge bases are off. On a SQLite store they stay off.
- **An embedding model.** A collection needs a catalog model with
`capabilities.embeddings`, for example bge-m3, whose weights are in the
mirror.
- **The client.** People download `llmgw-kb` for their system from this
release.
### Added
- **Collections and who may read them.** A collection is owned by an
organization, team, project or person. Grants add up down the tenancy
tree and never cross an organization. A collection a key may not read is
answered as one that does not exist. Chunks are kept in PostgreSQL with
pgvector, partitioned by organization, with an HNSW index per collection,
and row-level security on the table as a second line behind every
query's own filter. A project, team or organization that owns collections
is not deleted; a person's collections go with their account.
- **`llmgw-kb`**, its own download for Windows, macOS and Linux, run by
people with their own key. It reads documents where they are and sends
text and vectors, never the files, for what changed only; a SQLite ledger
on the machine remembers what it did.
- It reads PDF, Word, Excel, PowerPoint, OpenDocument, RTF, EPUB, HTML,
MHTML, mail with attachments, notebooks, subtitles, ZIP archives, and
text and source code in any common encoding.
- Legacy Office files are read with LibreOffice, and scanned pages with
Tesseract, when those are installed.
- `--dry-run` says what would leave the machine; `--delete` removes only
what that machine sent.
- **Answers from documents.** A chat request names collections in
`X-Llmgw-Knowledge`, or its part of the tree has a default (`llmgw ctl kb
default`). The best passages, chosen by meaning plus a little for the
question's words, are added to the system message, numbered, and
`x-llmgw-sources` says which were used. This happens before the
guardrails judge the request, and the answer is never served from the
answer cache. On vLLM replicas the organization's `cache_salt` keeps
tenants' prefix caches apart. It works through the Responses and Messages
APIs too.
- **Administration**: `llmgw ctl kb` (create, list, grant, revoke, default,
docs, rm, search, delete), `/api/v1/kb`, the console's Knowledge screen,
and a Documents picker on the portal's chat page.
- Metrics `llmgw_kb_retrievals_total` and `llmgw_kb_retrieval_seconds`;
[docs/knowledge.md](docs/knowledge.md).
## v0.13.0 — 2026-10-08
The whole system stopped, started and restarted from one command, a
guardrails judge that no longer refuses ordinary coding requests, and the
rest of the field report from v0.10.6.
**Upgrading.** A cluster keeps the judge its policies name: one installed
before this release goes on asking Llama Guard 3 1B until `llmgw ctl guard
judge use qwen3guard-0.6b`, which the leader then fetches and serves by
itself, and which replaces the policies' Llama Guard category codes.
### Added
- **A judge on a GPU and one on CPUs together**: a policy's `judge.models`
is a list asked in turn, the first that answers giving the verdict; the
next is asked when one has no replica serving, fails, or misses its
`latency_budget`. `llmgw ctl guard judge use qwen3guard-4b
qwen3guard-0.6b` sets the order for every policy with a judge, and
`guard judge status` says which judge stands in for which. A judge on a
GPU is served as a `standard` model, so it takes a card only from what
may give one up.
- **A judge a policy names is fetched if it is missing**: the leader
fetches the weights of a judge llmgw knows (`qwen3guard-0.6b`, `-4b`,
`-8b`, `llama-guard-3-1b`, `-8b`) into the mirror and serves it, when a
policy names it and the catalog does not have it — and again if it is
removed. `guard judge enable --gpu` serves Qwen3Guard-Gen 4B on the class
with the most free cards.
- **The whole system stops, starts and restarts from one command**: `llmgw
stop` takes every model down and answers every request for one with 503
(`system_stopped`), keeping the control planes, agents and mirror running
and no model's definition changed; `llmgw start` brings every model back.
It is the cluster's setting `serving.stopped`, live on every control plane.
`llmgw restart` restarts every node's agent and every control plane, the
leader last, with the engines serving throughout. `llmgw status` says
whether the system serves. One machine's services are `llmgw service
status|start|stop|restart`.
- **A replica says what it computes on**: `ctl replicas` (ON), the console
and the admin API show `CUDA` with the GPUs its processes hold memory on
and how much, as nvidia-smi sees them, or `CPU` — for every engine, kept by
the agent across its own and the control plane's restarts. llama.cpp's
layer count is added when it says it, which it does only at `-lv 4`.
- **`ctl engine-check llamacpp` computes a token on the GPU**: a small GGUF
(`--model`, or the smallest in the weights cache) is loaded with every layer
on the GPU at `-lv 4` and asked for one token; a build whose CUDA backend
does not load fails, by llama.cpp's own account of its layers. With no
`--bin` it checks the build the agent installed.
- **Engine versions and compute capability on nodes**: `ctl nodes` shows
`llamacpp b10991` and `6000-24g (7.5)`; the admin API gives
`engine_versions` and `compute_capabilities`. A profile's `engine_version`
restricts it to nodes whose engine version starts with it, and
explain-placement says which version a node has, or which engines.
- **`ctl restart --max-surge N` and `--max-unavailable N`**: that many of a
model's replicas restart at once, beside themselves or stopped first.
- **Multi-node readiness apart from the node's**: doctor gives both, with
fabric findings in a section of their own; `node add` says the multi-node
one; `ctl nodes` shows a declared fabric's adapters that are down.
- **A forgotten password is set through a link**: `/forgot` mails one when
the cluster's `mail` settings say how (SMTP, sender, the public
`base_url` it points at), saying the same whether or not the address has an
account; `/reset` sets the password once and closes every session. Without
mail, `llmgw users reset-link` makes the link for an operator to hand over.
### Fixed
- **A replica restarted in place keeps its room**: the replica was stopped
and the pass went on to other models before placing its replacement, so a
model waiting for room took the freed cards. On the reference cluster a
GPU judge waiting for the only card took it from the model being
restarted there. The replacement is now placed in the same step.
- **The judge no longer refuses ordinary coding requests**: Llama Guard 3
1B, the judge `server init` installed, could not tell "continue", "devam
et" or "how do I kill all child processes in bash" (0.51 to 0.92 unsafe)
from harmful requests (0.97 to 1.00), at any quantisation. The judge is
now Qwen3Guard-Gen 0.6B (format `qwen3guard`), which gave the same
ordinary requests 0.15 at the most and the harmful ones 1.00, on CPUs,
in 0.8 GB. Its third verdict, controversial, counts as safe unless the
policy says `controversial: unsafe`. `guard judge use qwen3guard-0.6b`
moves an installed cluster to it, and replaces Llama Guard's category
codes, which Qwen3Guard never names, with the baseline's.
- **A long message is judged rather than refused**: a judge read the whole
last user message, and one with a file pasted into it overflowed the
judge's context, so it gave no verdict and `fail: closed` refused the
request. It now reads the start and the end, about 6000 characters.
- **A replica no longer stays "starting" while it serves after a restart**:
an agent that registered before its adopted engines had answered their
health check never said they had, so the control plane kept them starting
and routed nothing to them — on the reference cluster, after `llmgw
restart`, the only replica of a model. The agent now reports each shard
the registration called not ready once it is.
- **A failover no longer replaces healthy replicas**: a standby that took
over placed at once, before the agents had reconnected and said what runs,
so it started a second copy of replicas it did not know of and then drained
the healthy ones as surplus — on the reference cluster the guardrails'
judge and a model's replica, within twenty seconds of a leader restarting.
Placement now waits after a takeover as it does at start.
### Changed
- **A GPU placement llama.cpp says it cannot compute on is refused** when it
warns that it found no usable GPU, even where nvidia-smi cannot be asked;
where it can, holding no memory on its GPUs refuses it as before.

Since v0.11.0, not yet released (see [CHANGELOG.md](CHANGELOG.md),
"Unreleased"):
Since v0.11.0 (each release's detail is in [CHANGELOG.md](CHANGELOG.md)):
- **Security hardening** — signed releases only, a token on the admin API,
engines not run as root, TLS for the agent port, etcd and Patroni, a
firewall for llmgw's internal ports, encrypted backups, bounded
connections, sign-in throttling, a Content-Security-Policy.
- **Guardrails** — policies that check requests and answers (PII, secrets,
prompt injection, deny patterns, a judge model such as Llama Guard), in
observe or enforce mode, attached to any part of the tenancy tree:
- **Picture and 3D models that add themselves** (v0.14.5). Where a node's
card fits flux-schnell or triposr and the catalog makes nothing of that
kind, the leader adds it on demand, so a new cluster's portal has its
Images and 3D pages; the cluster page and the console show each preset
and add it by hand, and `presets.auto` turns it off. Stable Fast 3D's
colours can be brought to the picture's (`albedo_match`), and every mesh
carries its whole licence.
- **Any ComfyUI workflow, and models by name** (v0.14.4). `POST
/v1/workflows/runs` runs a ComfyUI model's workflow as a job, its inputs
(text, numbers, choices, images, masks, audio, video, files) declared in
the catalog and listed in `/v1/models`. `llmgw ctl model add triposr` or
`flux-schnell` adds a tested model with no YAML; a profile may name the
card it needs instead of a class, and ComfyUI now installs on V100s. A
licence carries what a machine can match, and a person can leave
licences out on the profile page so no key of theirs reaches such a
model. A 3D job waiting for the one card says what holds it and for
about how long.
- **3D models as jobs** (v0.14.3). `POST /v1/3d/generations` answers with a
job, asked after until its mesh is ready to download. ComfyUI makes it on
the cluster's own cards, TripoSR being the tested model. The job says how
far along it is, the model's licence is written into the GLB, and
`per_mesh` prices it. People make them at `/3d` on the portal; `llmgw ctl
3d` shows every owner's jobs. A model profile may also load weights of
its own, and an admission band may wait longer than the rest, for bulk
work.
- **Pictures from ComfyUI** (v0.14.2). `POST /v1/images/generations` is made
by ComfyUI, behind a gate that demands the replica's key, as an engine the
agents install from its source checked against a digest. `per_image`
prices it, and people make pictures at `/images` on the portal.
- **Adapters, and the tenancy tree over the API** (v0.14.1). `llmgw ctl
kb dataset` and `llmgw ctl train` make a LoRA adapter from a collection
on a node's spare GPU memory, kept on the mirror and seen only by its
owner. Organizations, teams, projects, keys and memberships are in the
admin API and the Terraform provider. The agents' settings are edited
with the cluster's, on the portal too, and the firewall setting reaches
every machine.
- **Knowledge bases** (v0.14.0). People put a company's documents in from
their own machines with `llmgw-kb`, a separate download for Windows,
macOS and Linux that reads PDF, Office, OpenDocument, mail and many more
formats and sends text and vectors, never the files. Collections are kept
apart per tenant, down to row-level security in PostgreSQL. A chat
request, or a part of the tree by default, is answered from them with
its sources: [docs/knowledge.md](docs/knowledge.md).
- **One command for the whole system** (v0.13.0): `llmgw stop`, `start` and
`restart`. Qwen3Guard is the guardrails' judge, on a GPU and on CPUs
together.
- **Settings that apply when changed** (v0.12.0). The cluster's
configuration lives in the store, the same on every control plane and in
force within seconds (`llmgw ctl config`, the console's Settings). The
firewall can be switched on and off for the whole cluster.
- **Security hardening** (v0.11.2): signed releases only, a token on the
admin API, engines not run as root, TLS for the agent port, etcd and
Patroni, a firewall for llmgw's internal ports, encrypted backups,
bounded connections, sign-in throttling, a Content-Security-Policy.
- **Guardrails** (v0.11.2). Policies check requests and answers for PII,
secrets, prompt injection, deny patterns, and with a judge model; they
observe or enforce, and attach to any part of the tenancy tree:
[docs/guardrails.md](docs/guardrails.md).
- **Administration** — an audit log of every change (`ctl audit`), staff
roles (viewer, operator, billing, admin), single sign-on through OpenID
Connect and provisioning through SCIM 2.0, key lifetime limits and
rotation with overlap (`keys ttl`, `keys rotate`), usage export as CSV
(`ctl usage export`).
- **Notifications** — webhooks, signed or Slack-shaped, for a model parked,
a node lost, a budget spent and new weights published (`notify.webhooks`,
`ctl notify test`), and Alertmanager receiver templates.
- **Traffic and models** — request tags, canaries of new weights with
automatic rollback, quality suites gating updates, a response cache,
kept and replayed requests, batches, Anthropic's Messages API, more of
OpenAI's (structured output, images, rerank, audio, moderations),
scaling by the clock, SLO-aware admission, TensorRT-LLM, MIG, models
imported from Ollama, routing by what each vLLM replica's cache holds,
LoRA adapters loaded on demand, other llmgw clusters as providers, and
placement that knows racks, PDUs and power caps.
- **Operations** — `server restore` and off-machine backup copies, secrets
in Vault, forgetting a person and keeping a project's requests in the
cluster, offline installs from a bundle, a Helm chart, tracing from the
control plane to the engines, the admin API in OpenAPI with a Terraform
provider, and the portal in English and Turkish with its docs at /docs.

Answers the GLB's `file_id`, `url` and licence. |
| `review_images` | Asks a vision model about one to four pictures (each shrunk to 1280 px on its long side); `json_schema` makes it answer that JSON. |
| `run_workflow` | Runs a ComfyUI workflow from the inputs its catalog entry declares, and answers its result file. |
| `job_status` | Where a mesh or a workflow run stands, and its file when done; `wait_seconds` waits for it. |
| `gateway_status` | The picture, 3D, vision and workflow models, whether each is loaded on a GPU now, a workflow's inputs, and your last jobs. |
Each tool makes its request of the gateway under your key, so your
allowlist, limits, left-out licences and budget apply, and it is charged
and listed like any other request. What it makes is kept as your file for
as long as job results are: fetch it from `url` with the same key (`curl -H
"Authorization: Bearer $LLMGW_API_KEY" -o rock.glb <url>`). A tool server
over HTTP cannot write to your disk, so an agent that needs the file
locally — to import it in Blender — fetches it, or goes through a small
local bridge that does.
A picture can be uploaded once and named by its id after: `POST /v1/files`
with `purpose=vision` (or `user_data`) keeps it, for as long as job results
are kept, as a file of yours that `generate_mesh`, `review_images` and a
workflow's file inputs take as `file-…`. A call is at most 64 MB.
A model that is not loaded is waited for: a picture or a look at one whose
model is starting, or waiting for another to give up the GPU, waits as a
mesh does, saying so, rather than failing with "model loading".
A mesh takes from half a minute to a few minutes. A client that takes the
answer as a stream (`Accept: text/event-stream`, as Claude Code does) is
answered that way: `notifications/progress` for the call's
`progressToken` while it runs — queued, waiting for the GPU, the node and
its percent — then the result, and the call waits up to ten minutes. One
answered in one piece waits 50 seconds; a job not done by then is answered
with its `job_id`, to ask after with `job_status`. `wait_seconds` (up to
900) sets either.

### Licences you leave out
A model's licence is in `/v1/models` (`license`: its `id`, `name`, whether
it allows commercial use and the regions it grants nothing in). On your
profile page, under **Licences**, you can leave licences out: one by one,
every licence that forbids commercial use, or every licence that grants
nothing in a region you name (`EU` for the union). The rules cover models
added later too. From then on those models are not listed to your keys and
a request for one is refused with 403 and the code `licence_excluded`,
naming the choice that left it out — on every key you own and on the
portal's pages, whatever a key's own allowlist says. A change reaches keys
already in use within a minute.

say which judge and why.
### Which judge
| judge | runs on | size | |
|---|---|---|---|
| `qwen3guard-0.6b` | CPUs | 0.8 GB | the default: about 2 s a check on two threads |
| `qwen3guard-4b` | a GPU | 2.5 GB | for a cluster with a card to spare |
| `qwen3guard-8b` | a GPU | 4.7 GB | |
| `llama-guard-3-1b` | CPUs | 0.9 GB | the earlier default: refuses ordinary coding requests |
| `llama-guard-3-8b` | a GPU | 4.6 GB | |
Measured on the reference cluster, as the judge's probability of "unsafe"
for ordinary coding requests against harmful ones, Llama Guard 3 1B could
not tell them apart: "continue" 0.51, "continue the code above" 0.89, "how
do I kill all child processes in bash" 0.92, against 0.97 to 1.00 for
harmful requests, at any quantisation. Qwen3Guard-Gen 0.6B gave the
ordinary ones 0.15 at the most and the harmful ones 1.00. Its verdicts are
safe, unsafe and **controversial**; controversial counts as safe unless the
policy says `controversial: unsafe`.
A policy that names one of these is enough: the leader fetches its weights
into the mirror and serves it as a judge, and serves it again if it is
removed from the catalog. Another judge is served by hand with `--repo`.

```
or **Do → Serve the guardrails' judge** in the console.
**When it refuses ordinary requests.** A refusal by a judge names the hazard
it saw — the client is told `refused by the gateway's policy (judge:
S6,Specialized Advice)` — and the same is kept with the request: `llmgw ctl
request <id>`, the server's log (`guard_rule`) and the guardrails page show
it. To see what the judge says of any text, without anything being kept:
### A GPU and CPUs together
`judge.models` is a list asked in turn: the first judge that answers gives
the verdict. The next is asked when one has no replica serving, fails, or
does not answer within `latency_budget`; a judge with no replica at all is
passed over at once. A judge on a GPU first and one on CPUs after it is
the GPU's speed while it has its card, and the CPUs' when it does not.
```yaml
judge:
models: [qwen3guard-4b, qwen3guard-0.6b]
input: block
output: block
latency_budget: 5s # each judge's wait
```
A judge on a GPU is served as a `standard` model, on one card: it takes a
card only from what may give one up, and waits while every card is busy,
the judge on CPUs standing in. A judge on CPUs is `critical`, with two
replicas, because every judged request waits on one. `llmgw ctl guard judge
status` says, for each judge, which is asked when it gives no verdict.
### When it refuses ordinary requests
A refusal by a judge names the hazard it saw — the client is told `refused
by the gateway's policy (judge: Violent)` — and the same is kept with the
request: `llmgw ctl request <id>`, the server's log (`guard_rule`) and the
guardrails page show it. To see what the judge says of any text, without
anything being kept:
```
llmgw ctl guard judge ask 'How do I sort a list in Python?'
# llama-guard-3-1b: safe, 140 ms
# it answered: "safe"
# qwen3guard-0.6b: safe, 1900 ms
# it answered: "Safety: Safe\nCategories: None"
```
A judge that says `unsafe` to ordinary text is usually the wrong weights
(another repository's or quantisation's, without Llama Guard's template:
`judge enable --replace` serves the right ones), or a policy counting every
hazard: give its judge `categories`, leaving out S5, S6, S8 and S13 as the
baseline does. While finding out, `judge.input: flag` records instead of
refusing. A Llama Guard file
served from the mirror page is served as a judge too, under the name the
policies ask. By hand, the catalog entry is:

### Pictures from ComfyUI
Clients ask for pictures at OpenAI's `/v1/images/generations`. llmgw has them
made by ComfyUI: it fills a ComfyUI workflow with the request, queues it,
waits, and sends the pictures back as `b64_json`.
**On the cluster's own cards.** Use engine `comfyui`. The model is placed on a
GPU node like any other, started when asked for, and stopped when unused.
**The short way: a preset.** Some models come with llmgw, with their
workflow, custom nodes, packages and licence already found and tried:
```
llmgw ctl model presets
llmgw ctl model add flux-schnell # pictures, Apache 2.0, a card of 24 GB, Volta or newer
llmgw ctl model add triposr # 3D models from a picture, MIT, a card of 8 GB
```
A preset's profile says the card it needs, not a class, so it places on
whatever cards the site has. When the cluster's settings name no ComfyUI,
adding one sets `engines.comfyui` to the version this release installs, and
every node with an NVIDIA GPU installs it; a cluster that names a version,
or `""` for none, keeps it; the control planes then start again on that
setting, standbys first.
They also come by themselves. Once a node has a card that fits one, and the
catalog has nothing that makes what it makes, the leader adds it, on demand —
where the cluster already installs ComfyUI; it never sets `engines.comfyui`
by itself. A preset somebody removes stays out until it is added again.
`llmgw ctl model presets auto off` (the setting `presets.auto`) stops it.
The cluster page on the portal has a **Pictures and 3D models** card under
the models: each preset, the classes of card here it fits, whether it is in
the catalog and who added it, why the leader has not, an **Add** button (one
that would also install ComfyUI says so first) and the switch for adding
them by themselves. In the console, the models screen shows the same: **A**
adds one, **P** turns adding them by themselves on or off.
`llmgw ctl model presets` prints it. The rest of this section is for a model
of your own.
The node must offer the engine. Ask for it in the cluster's settings, and every
node with an NVIDIA GPU installs it:
```
llmgw ctl config set engines.comfyui 0.39.2
```
The agent fetches ComfyUI's source from GitHub and checks it against the
digest llmgw holds for that version. GitHub publishes none for a tag's archive,
so a version llmgw does not know is refused. The agent then builds a Python
environment beside the source, under `/opt/llmgw/engines/comfyui/`. Its
dependencies are resolved as PyPI stood the day after the release. torch comes
from PyPI (CUDA 13), from PyTorch's CUDA 12.9 build where the driver is older
than 580, or from its CUDA 12.6 build on cards older than Turing (a V100):
torch's CUDA 12.8 and newer builds have no kernels for them. The install is
checked on the node's GPU, and takes about 10 GB.
`engine_overrides` can keep it off nodes that should not have it.
Alternatively, install ComfyUI by hand. You need a directory with `main.py` and
its environment in `.venv`, readable by the user engines run as
(`llmgw-engine`). Name it in that node's `agent.yaml`; a node with one named
there is not given the installed one:
```yaml
engines:
comfyui:
dir: /opt/comfyui # python: defaults to /opt/comfyui/.venv/bin/python
```
Then add the model:
```yaml
- name: flux-schnell
source: hf:Comfy-Org/flux1-schnell/flux1-schnell-fp8.safetensors
comfyui:
workflow: flux-schnell # or flux-dev, or a JSON file
scaling: {min: 0, max: 1, idle_timeout: 15m}
profiles:
- name: gpu
engine: comfyui
gpu_class: 6000-24g
tp: 1
```
The source is fetched as for any model. It can be one file, such as the
single-file checkpoints the built-in workflows load. It can also be a mirror
set (a URL ending in `/`) for a model in several files, such as a diffusion
model, its text encoders and its VAE. ComfyUI sees every file of a set by its
own name, so a workflow of your own can load each one. A set must name the
file that `{{checkpoint}}` stands for in `comfyui.checkpoint`. A single file
is named by its own file name.
ComfyUI asks nobody for a key. The agent therefore starts it behind a gate
(`llmgw comfyui-gate`). ComfyUI listens on the node's loopback only. The gate
listens on the replica's port, demands the replica's key, and lets through only
what the router asks: queueing, waiting, fetching a picture and cancelling.
Uploads and node installs are refused. Each replica has its own directory,
`~llmgw-engine/comfyui/REPLICA`, and ComfyUI's output can be read with `llmgw
ctl logs NODE --source SHARD`. A profile's `args` go to `main.py`.
`--disable-smart-memory` frees the card between pictures, at the cost of loading
the model again for each one.
**On a ComfyUI server outside the cluster.** Make it an external model with
`api: comfyui`:
```yaml
- name: flux-schnell
source: external
external:
url: http://10.0.0.147:8188 # ComfyUI, started with --listen
model: flux1-schnell-fp8.safetensors # the checkpoint, as ComfyUI lists it
api: comfyui
workflow: flux-schnell # or flux-dev, or a JSON file
```
Like any external model, its requests count as leaving the cluster.
`flux-schnell` (the default) and `flux-dev` are built in. They suit the
single-file FLUX checkpoints that ComfyUI loads with `CheckpointLoaderSimple`.
For any other model, export the workflow from ComfyUI with **Save (API)** and
name the file. In the file, put placeholders where the request's values go:
- `{{prompt}}` and `{{negative_prompt}}` are the prompts.
- `{{width}}` and `{{height}}` are the size.
- `{{n}}` is the batch size.
- `{{seed}}` is the seed.
- `{{steps|4}}` and `{{guidance|3.5}}` take the value after the `|` when the
request leaves them out.
- `{{checkpoint}}` is the `model` above.
A request is OpenAI's: `prompt`, `n` (at most 4), `size` (each side a multiple
of 16, from 256 to 2048) and `response_format: b64_json`. Beyond those, it may
send `seed`, `steps`, `negative_prompt` and `guidance`. The seed used comes
back in `x-llmgw-seed`. `url` is not offered, because pictures are kept
nowhere. ComfyUI also writes the workflow into each PNG; llmgw strips it
before the picture is sent.
Requests for pictures pass the same checks as any other request: keys,
allowlists, limits, admission, and the guardrails on the prompt. A client that
leaves takes its workflow off the ComfyUI queue.
Each request's usage row records how many pictures it made (`llmgw ctl request
ID` shows them). A picture's price is set with `per_image`, in micro-units like
the other prices, and is charged on top of the prompt's tokens:
```yaml
auth:
pricing:
flux-schnell: {prompt_per_1k: 0, per_image: 20000}
```
An external ComfyUI on a card that llmgw also places models on should be
started with `--disable-smart-memory`. Without it, ComfyUI keeps the model on
the card after each picture, and llmgw sees that memory as somebody else's.

## Jobs: 3D models
A 3D model from a picture takes minutes on a card that first has to be
emptied of whatever else was on it. No client should hold a connection for
that, so it is a job: queued, answered with an id, asked after, its result
downloaded.
```
curl http://gateway:8080/v1/3d/generations -H "Authorization: Bearer $LLMGW_API_KEY" \
-d '{"model": "trellis2", "image": "<base64>"}'

curl -X POST http://gateway:8080/v1/3d/generations/job_…/cancel -H "Authorization: Bearer $LLMGW_API_KEY"
```
- **Status:** `queued`, `running`, `completed`, `failed` (with `error`),
`cancelling`, `cancelled`, `expired` (not finished within 24 h).
`progress` carries what the engine said of the work so far, once it says
anything; `GET /v1/3d/generations` lists the caller's jobs. While the
model waits for another on-demand model to give up the card,
`progress` is `{"state":"waiting_gpu","held_by":"flux-schnell","eta_seconds":N}`:
N is when the holder is stopped (idle and old enough to evict, or at its
idle timeout) plus how long the model's last start took, and is left out
when that is not known. A request made directly gets the same as a 503
with `X-Llmgw-Waiting-For`, `X-Llmgw-Eta-Seconds` and `Retry-After`.
- **Refused at the door:** no key, a model that is not there or not in the
key's allowlist, a request the model cannot serve. Refused when served,
and said as the job's error: a spent budget, the guardrails, a model
that will not come up.
- **How it is served:** the request is kept as it was sent and replayed by
whichever gateway holds the job's lease, through the same path a
client's request takes — limits, admission in the key's band, guardrails,
accounting — by the leading control plane, since a standby has nothing
to send it to. A model said to fit nowhere is asked for again for five
minutes before that is the job's error: an agent re-registering says so
for a few seconds. It is one usage record under the job's id, tagged
`job=<id>`, charged like any request; `GET` shows the usage once it is
done. A model still loading, a rate limit or a full queue is waited out
for as long as the job has: nobody is holding a connection, which is the
point.
- **Surviving a restart:** a gateway that stops hands its jobs to another
within two minutes; a job it was running is run again from the start.
- **What it keeps:** the request as sent, and the result as a file owned
by the key's project, kept `router.batch.retain_days` (30) like a batch's
files; the job's record goes with it. A project under a `no_store`
policy is refused jobs, as it is batches.
A request may also send `seed` and `resolution` (the model's own grid, a
multiple of 32 from 64 to 2048). The picture should show one object on a
plain background: the model makes a mesh of what it sees, background
included.
### A model that makes them
A 3D model is made by a ComfyUI model whose `comfyui.output` is `meshes`
(see [Pictures from ComfyUI](#pictures-from-comfyui) for engine `comfyui`).
Its workflow is a JSON file in ComfyUI's API format: `{{image}}` is the
uploaded picture, which a `LoadImage` node reads; `{{seed}}`,
`{{resolution|256}}` and `{{checkpoint}}` are as for pictures. The node that
saves the mesh may save a GLB or an OBJ; an OBJ leaves the gateway as a GLB,
vertex colours kept.
TripoSR (MIT), on any card of 8 GB, comes with llmgw: `llmgw ctl model add
triposr`. What that adds is this entry, and its workflow is built in:
```yaml

`LLMGWPrepareForMesh` comes with the gate: it cuts the object out — by the
picture's alpha, or by rembg where it has none — and centres it on a plain
background, without which the background becomes geometry.
- **Custom nodes** are named by https repository and full commit (a branch
is refused: it moves). The gate puts each in the replica's own
`custom_nodes` and installs its `requirements` beside the replica, never
into ComfyUI's environment. A package named there is installed at the
range named; every other one at the version ComfyUI already runs. A
package named is first on ComfyUI's path, so its range must suit ComfyUI
as well. TripoSR's checkpoint loads with transformers 4, which ComfyUI's
`>=4.50.3` allows.
- **Progress:** the gate listens to ComfyUI's websocket and the router
writes what it hears into the job: `{"state": "queued", "ahead": 2}`,
then `{"state": "running", "node_class": "KSampler", "step": 12,
"steps": 30, "percent": 40}` for a node that counts its steps, and
`done` at the end.
- **Licence:** a model's `license` is shown in `/v1/models`, in the job and
on the portal, and written into the GLB's `asset.extras.license`, since
the file travels without the API. Choose the model for its licence before
its quality when what it makes is shipped. TRELLIS.2 needs Meta's gated
DINOv3 and, as published, a background remover under a non-commercial
licence; Hunyuan3D's licence excludes the EU, the UK and South Korea.
- **Price:** `per_mesh` in `auth.pricing`, beside `per_image`; each usage
row says how many meshes it made (`meshes`).
- **Cards:** the strongest models today (TRELLIS.2, Direct3D-S2) need
flash-attention, which runs on Ampere and newer. A Turing card such as
the RTX 6000 runs TripoSR.
People make them at `/3d` on the portal: they choose a picture and watch
the job, and the mesh is shown in a viewer (model-viewer, served from the
gateway) with a download link and the licence. `llmgw ctl 3d list`, `get`
and `cancel` show and stop every owner's jobs.

agents and mirror keep running, so the console, the admin pages and `llmgw
start` keep working, and no model's definition changes. It is the cluster's
setting `serving.stopped`, so a restart does not undo it, and it is in the
audit with its note. `--wait` waits until every replica is down, or every
model has its replicas again.
`llmgw restart` restarts every node's agent, then the other control planes
over ssh (`--ssh-user`, the one sudo was run by), then this one — the leader
last, so it hands over to a standby already restarted. Engines keep serving
and are taken over again; nothing is placed anew.

too, and the control plane then places their replicas elsewhere.

# Knowledge bases
A knowledge base is a collection of a company's documents that the cluster
can answer from. People put their documents into it from their own machines
with `llmgw-kb`. The tool reads the files on that machine, cuts them into
passages ("chunks"), has the gateway embed each passage with the person's own
key, and sends the text and the vectors. The files themselves never leave
the machine.
## Why retrieval, and not training
Retrieval is the tool for *knowledge*: policies, procedures, contracts. The
answer can name its source, a changed document is sent again in minutes, and
a passage only ever reaches people allowed to read its collection.
Training a model on the documents (LoRA) changes how it *writes*, not what it
reliably *knows*. It has no access control: whatever goes into the weights
is available to everyone who may use them.
## What it needs
- **The PostgreSQL store with pgvector.** On a SQLite store knowledge bases
are off, and `llmgw ctl kb list` and the console say why.
- `llmgw server init` and the high-availability database setup install
pgvector and enable it.
- A cluster set up before this build needs it by hand, once:
1. Install the package on every database machine:
`sudo apt-get install postgresql-16-pgvector` (use the server's
version number).
2. On the leader, enable it in llmgw's database:
`sudo -u postgres psql -d llmgw -c 'CREATE EXTENSION vector'`.
3. Restart the control planes: `llmgw restart`.
- **An embedding model in the catalog**, with `capabilities.embeddings`.
Two good choices handle Turkish and run on CPUs: `BAAI/bge-m3` (1024
dimensions) and `Qwen/Qwen3-Embedding-0.6B`.
Add it as any model is added (**Serve a model** in the console, or the
catalog), with its entry saying that it embeds:
```yaml
capabilities:
embeddings: true
```
A collection stays with the model it was made with: vectors from two
models cannot be compared.
Some embedding models are trained with an instruction before the
question and none before the documents. Give it as the entry's
`query_prefix`; llmgw puts it before questions only. For
Qwen3-Embedding:
```yaml
query_prefix: "Instruct: Given a web search query, retrieve relevant passages that answer the query\nQuery: "
```
With pgvector 0.7 or later a collection's index is kept at half
precision (`halfvec`), which halves its memory and takes models of up to
4000 dimensions; with an older pgvector the limit is 2000. A collection
keeps the kind it was made with.
## For administrators
### Make a collection
A collection belongs to one part of the tenancy tree: an organization, a
team, a project or a person. Whoever is in the owner, at any level below it,
may read it and add to it.
```sh
llmgw ctl kb create team:Acme/hr policies bge-m3
llmgw ctl kb create user:USER-ID notes bge-m3 --org Acme
```
The model's dimension is asked of the model itself, so the model has to be
able to serve when the collection is made. `--dims 1024` gives it instead.
In the console: **Knowledge**, then **A**.
### Who may read and add
The owner, and everything below it, may read and add. A **grant** gives the
same to another part of the same organization, to a person, or to one key:
```sh
llmgw ctl kb grant Acme/policies project:Acme/sales/crm # read
llmgw ctl kb grant Acme/policies team:Acme/legal --write # read and add
llmgw ctl kb revoke Acme/policies project:Acme/sales/crm
```
How access works:
- **Grants add up down the tree.** A grant to a team reaches its projects
and their keys.
- **Nothing crosses organizations.** A grant to another organization's
team, project, key or person is refused.
- **A person's own key** (a key with no project) reads nothing by itself.
The person names the project they act in (`llmgw-kb login` asks for it,
or `--project`) and must be a member of it. Joining a second team
therefore does not quietly widen what every key of theirs can read.
- **No access looks like no collection.** A collection a key may not read
is answered exactly as one that does not exist, so even its name does not
leak.
### Answer from collections by default
Clients that cannot add a header still get answers from the documents when
their part of the tree has a default:
```sh
llmgw ctl kb default team:Acme/hr Acme/policies Acme/forms
llmgw ctl kb default key:KEY-ID Acme/policies
llmgw ctl kb default team:Acme/hr --clear
```
- **Which default applies.** The narrowest one: a key's over its project's,
a project's over its team's, a team's over its organization's.
- **A request can override it.** A request that names collections uses
those instead, and `X-Llmgw-Knowledge: none` turns the default off for
that request.
- **A default never refuses a request.** A collection the caller may not
read is left out for them. If the search fails (the embedding model is
down, say), the request is answered without passages and the failure is
logged.
- **Changes take effect within 30 seconds.**
In the console: **Knowledge**, Enter on a collection, then **Answer from it
by default…**.
### Look after it
```sh
llmgw ctl kb list # collections, owners, documents, grants
llmgw ctl kb docs Acme/policies # its documents, who added each and when
llmgw ctl kb rm Acme/policies old/form.pdf # one document out
llmgw ctl kb search Acme/policies how many days of annual leave
llmgw ctl kb delete Acme/policies # the collection, its documents and grants
```
Rules that apply:
- A project, team or organization that owns a collection is not deleted
until its collections are. This is the same rule as for one with members.
- A person's own collections go with their account (`users delete`,
`users forget`).
- Every document added or removed is in the audit log (`llmgw ctl audit`),
by name. The text is never recorded.
### A large import
A few thousand documents ask the embedding model for far more than it can
answer at once. Give the key that sends them a band of its own, below the
people's, that may wait for room for minutes rather than the 30 seconds the
others wait:
```sh
llmgw ctl config set router.admission.bands '[{name: gold, priority: 300, saturation_ceiling: 0.85},
{name: bronze, priority: 100, saturation_ceiling: 0.3}, {name: bulk, priority: 50, saturation_ceiling: 0.3, queue_ttl: 5m}]'
llmgw keys create import --project Acme/docs --band bulk
```
The people's questions then go first, and the import waits behind them. A
request that waits as long as its band allows is answered 504 with
`Retry-After`, and `llmgw-kb` sends it again rather than counting the
passage as failed. It gives up after 15 minutes.
## For everyone: `llmgw-kb`
### Get it
Download `llmgw-kb` for your system from the release page, next to `llmgw`:
| System | File |
|---|---|
| Windows (Intel/AMD) | `llmgw-kb-VERSION-windows-amd64.exe` |
| Windows (ARM) | `llmgw-kb-VERSION-windows-arm64.exe` |
| macOS (Apple silicon) | `llmgw-kb-VERSION-darwin-arm64` |
| macOS (Intel) | `llmgw-kb-VERSION-darwin-amd64` |
| Linux | `llmgw-kb-VERSION-linux-amd64` / `-arm64` |
Rename it to `llmgw-kb` (`llmgw-kb.exe` on Windows) and put it somewhere on
your PATH. You do not need to install anything else.
On macOS, a downloaded program that is not signed is stopped the first time.
Either right-click it and choose Open, or run
`xattr -d com.apple.quarantine llmgw-kb`.
### Log in once
```sh
llmgw-kb login
```
It asks for three things, checks them, and saves them where only you can
read them:
- **The gateway's address.**
- **Your API key.** It is typed without being shown.
- **A project.** Needed only for a personal key.
Instead of logging in you can set `LLMGW_URL`, `LLMGW_API_KEY` and
`LLMGW_PROJECT`.
```sh
llmgw-kb collections # what your key may read, and which you may add to
```
### Send your documents
```sh
llmgw-kb sync policies ~/Documents/HR
llmgw-kb sync policies "C:\Users\ayse\Documents\İK" --include "*.pdf,*.docx"
llmgw-kb sync policies ./handbook ./forms --exclude "drafts/**"
```
Run it as often as you like. The first run sends everything. Later runs
send only what changed, and do not even read files whose size and time have
not changed.
| Option | What it does |
|---|---|
| `--dry-run` | Reads and cuts everything, sends nothing, and lists what would leave the machine and how much. |
| `--delete` | Also removes documents whose files are gone. Only those this machine sent, from these folders; never anything someone else sent. |
| `--retry` | Reads again files skipped before, for example after installing LibreOffice. |
| `--include`, `--exclude` | Glob patterns. `*.pdf` matches a file name; `reports/**/*.xlsx` matches a path. |
| `--hidden` | Reads hidden files and folders too (left out by default). |
| `-v` | Lists unchanged files too. |
Documents are named by their path under the folder, with forward slashes,
on every system. With several folders, each folder's own name comes first.
```sh
llmgw-kb status policies # what this machine sent and skipped, and why
llmgw-kb history # the latest runs
llmgw-kb formats # what can be read here
```
### What it reads
| Read here | Formats |
|---|---|
| Documents | PDF (text), Word (`.docx`), Excel (`.xlsx`), PowerPoint (`.pptx`, with speaker notes), OpenDocument (`.odt`, `.ods`, `.odp`), RTF, EPUB |
| Web and mail | HTML, MHTML, e-mail (`.eml`, with its attachments) |
| Text | Markdown, plain text, CSV, JSON, YAML, XML, subtitles, notebooks (`.ipynb`), source code |
| Archives | ZIP, with every file inside it read in turn |
| Read with a helper on your machine | Helper |
|---|---|
| Word, Excel and PowerPoint 97–2003 (`.doc`, `.xls`, `.ppt`), Pages, Numbers, Keynote and others | [LibreOffice](https://www.libreoffice.org) |
| Images and scanned PDFs | [Tesseract](https://tesseract-ocr.github.io) (with the Turkish language data), plus Poppler's `pdftoppm` for PDFs |
| PDFs the built-in reader cannot parse | Poppler's `pdftotext` |
`llmgw-kb formats` says which helpers it found. Text in UTF-8, UTF-16, or
the Windows Turkish and Western code pages is read correctly.
A file that cannot be read is skipped with the reason, and the run goes on.
Reasons include a locked Office file, a format with no helper, and a
scanned page with no OCR.
### What leaves your machine
For each new or changed document, two things leave the machine, both over
the gateway's TLS connection:
- **The passages, to be embedded.** They go through `/v1/embeddings` like
any request of yours. Your key's limits, budget and guardrails apply.
- **The document itself.** Its name, its file's SHA-256 digest and size,
and the passages with their vectors.
The file itself is never sent. `--dry-run` shows exactly what would be.
### The ledger
`llmgw-kb` keeps a small SQLite database of what it did with every
document: the file it came from, its size, time and digest, and whether it
was sent, skipped or failed, with the reason.
| System | Where it is |
|---|---|
| Windows | `%AppData%\llmgw-kb\ledger.db` |
| macOS | `~/Library/Application Support/llmgw-kb/ledger.db` |
| Linux | `~/.config/llmgw-kb/ledger.db` |
Deleting the ledger is safe: the next run hashes every file once, finds what
the collection already has, and sends nothing that is unchanged. `--ledger`
uses another file.
## Asking questions of a collection
A chat request names the collections to answer from in a header. Any client
that can add a header can do it: the OpenAI and Anthropic SDKs, Continue, or
curl.
```sh
curl https://llm.example.com/v1/chat/completions \
-H "Authorization: Bearer $LLMGW_API_KEY" \
-H "X-Llmgw-Knowledge: politikalar" \
-d '{"model": "qwen2.5-coder-14b-instruct",

1. **It finds the collections.** It looks up the ones named, by name or ID,
among those the key may read. A collection it may not read is answered
404, the same as one that does not exist.
2. **It embeds the question.** The last user message is embedded by the
collection's model, on the caller's own account: their limits, budget and
guardrails apply.
3. **It searches.** The collections are searched by meaning and by words
(below).
4. **It adds the passages.** The best passages are numbered and added to the
system message, with an instruction to answer from them, cite them as
[1], [2], and say so when they do not hold the answer. The system message
is created if the request has none. Passages that would not fit the
model's context are left out, the weakest first.
5. **It judges and sends the request.** The request, passages included, then
goes through the guardrails and to the model as usual. A document
carrying instructions aimed at its reader is judged like anything else
the model reads.
On the portal's chat page, **Documents** picks a collection the person may
read in the chosen project, the default, or none. Under each answer, the
sources it was given are listed by number.
How it is shaped:
| | |
|---|---|
| `X-Llmgw-Knowledge` | Collections, comma separated; `none` for no passages, whatever the default. |
| `X-Llmgw-Knowledge-K` | How many passages, 1 to 20; 5 by default. |
| `X-Llmgw-Project` | For a personal key: the project it acts in. |
| `x-llmgw-sources` (answer) | The passages given, as `document#chunk`, in their numbered order; empty when nothing matched. |
Behaviour to know about:
- **No passages matched.** The model is told that nothing in the documents
answers the question, and asked to say so rather than answer from general
knowledge.
- **Other APIs.** Requests through `/v1/responses` and `/v1/messages`
(Codex, Claude Code) work the same way, since they are answered as chat
completions.
- **Separate prefix caches.** On vLLM replicas, a request given passages
carries a `cache_salt` derived from the collections they came from.
Requests that could be given the same passages still share cached blocks,
and no one else's do: not another organization's, nor another team's of
the same one. How fast an answer starts therefore says nothing about what
someone else asked.
- **No answer cache.** Answers from knowledge bases are never served from
the answer cache, because two keys of one project can read different
collections.
### How a passage is chosen
Each passage scores the following, and the highest scores win:
- its similarity in meaning to the question (cosine, 0 to 1), plus
- up to 0.3 for the share of the question's words it contains.
Words almost every passage has ("ne", "için", "the", "of") are not counted.
The meaning does most of the work: "how much leave do fathers get" finds the
paternity page, not the annual-leave page that shares more of its words.
The word match helps with what meaning cannot carry, such as a form number,
a product code or a name.
Metrics: `llmgw_kb_retrievals_total{result}` (found, nothing, refused) and
`llmgw_kb_retrieval_seconds`.
## Training an adapter on a collection
An adapter (LoRA) changes how a model *writes*: the organisation's words,
format and tone. It does not reliably teach facts. On the PoC, a small
model trained on nine policy documents answered 4 of 9 rephrased questions
right and mixed facts up on the rest, while the same questions through the
knowledge base got 9 of 9. Use both: the knowledge base for what answers
say, an adapter for how they sound.
```sh
# 1. Questions and answers from the collection, written by a model of the
# cluster. Read the file through and correct it.
llmgw ctl kb dataset Acme/policies --model qwen2.5-coder-14b-instruct --out policies.jsonl
# 2. Train on a node. --gpu-memory is what the job needs of a card; it
# runs beside an engine when the engine leaves that much free.
llmgw ctl train start policies-tone --model qwen2.5-0.5b-instruct \
--base-repo Qwen/Qwen2.5-0.5B-Instruct --node cuda01 --gpu-memory 2300 --data policies.jsonl
llmgw ctl train show JOB --follow
# 3. Make it the model's adapter, kept on the mirror.
llmgw ctl train publish JOB --restart
```
The node trains with its installed vLLM's torch and a small overlay (peft
and accelerate), as the engines' user. For a model llama.cpp serves, it also
converts the adapter to GGUF with the installed llama.cpp's own code. What
it makes is kept by the control plane (`llmgw ctl train download`).
An adapter is private like its collection:
- **It has an owner.** An adapter trained on a collection carries some of
what the collection says in its weights, so it belongs to a part of the
tree.
- By default the owner is the collection's owner.
- `--owner` names another, which must be able to read every collection
the pairs came from.
- Only callers in the owner's part of the tree see the adapter. To anyone
else it is a model that does not exist, absent from `/v1/models` too.
- **It is public only by choice.** `--public` makes an adapter every
caller's. It is refused for pairs from a knowledge base, so it is only for
pairs written by hand.
## How it is kept apart
Passages live in PostgreSQL, partitioned by organization, with an index per
collection. Every search and every write names the organization and the
collections the caller may use. On top of that, row-level security on the
table checks the same thing again, so a query that forgot its filter
returns nothing rather than another tenant's passages.

There is no self-service reset, because this gateway sends no email and a reset
link with nowhere to send it is not a reset. When someone loses theirs:
Someone who has forgotten theirs follows **Forgotten your password?** on the
sign-in page. With mail set up in the cluster's settings, a link to set a new one
is mailed to their address — the page says the same whether or not the address
has an account, so nobody can find out who does from it:
```
llmgw ctl config set mail '{smtp: smtp.example.com:587, from: llmgw@example.com,
username: llmgw, password_file: /etc/llmgw/secrets/smtp, base_url: https://llm.example.com}'
```
`base_url` is where the link points, and it is never taken from the request:
otherwise a stranger could ask for someone's link from a page of their own. A
link works once, for an hour, and a newer one replaces it.
Without mail, the page says to ask an operator, who makes the link and hands it
over however suits:
```
llmgw users reset-link ayse@example.com --store … # --base-url without mail.base_url
```
Or sets a temporary password to give them, and has them change it from their
profile:
```
llmgw users reset-password usr-k4mq… --password "a temporary passphrase" --store …
```
Tell them out of band and have them change it from their profile. Their sessions
