### 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.

|
||||
took 3 h. Done (2026-10-10, branch `admission-bulk`): a source per

|
||||
profile llama.cpp; a band's own `queue_ttl` for bulk imports, and

|

## 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`.

### 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
|
||||
@@ -41,6 +452,61 @@ APIs change between minors without a deprecation period.
|
||||
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.

|

Since v0.11.0 (each release's detail is in [CHANGELOG.md](CHANGELOG.md)):
|
||||
|
||||
- **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

the identity provider (OIDC, SCIM); the API lists them and puts them in

the tree, and `llmgw users` approves, disables and deletes them. Key

no key, so a client generator can be pointed at it. `/docs/api` shows it in
|
||||
Swagger UI, where *Authorize* takes a key and *Try it out* sends a request to

the gateway. People with a part in running the gateway also find the admin
|

API's document there.

**Pictures, 3D models, vision and workflows.** Where the gateway has the
|
||||
models for them, the same server offers more tools — only those it has a
|
||||
model for:
|
||||
|
||||
| Tool | Does |
|
||||
|---|---|
|
||||
| `generate_image` | A picture from a prompt. `style` adds what a picture for a mesh wants: `concept` (one object, three-quarter view, grey background), `side` (an exact side view), `texture` (a seamless tile) or `none`. Answers the PNG's `file_id`, `url` and `seed`, with a 512 px preview to look at. |
|
||||
| `generate_mesh` | A GLB from a picture — `image` is a `file-…` id (a `generate_image` result, say), a data URL or base64 — or from a `prompt`, for which a concept picture is made first. `seed`, `resolution`, `texture_resolution`, and any other input the model's workflow declares in `inputs`. 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.

### 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}
|
||||

||||
- 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.

|
||||
`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

||||

|
||||
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.

`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.

## 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 \

||||

|
||||
|
||||
# 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.

Checkpoint is the file the workflow's {{checkpoint}} names: the

|

Environment names the models that may share one ComfyUI replica: every

one replica can carry all of them and ComfyUI moves between their
