/admin/mcp, for administrators only, since a server's credential reaches
whatever it guards: each server's state, who has been granted its tools,
its rate, the headers it is sent by name with the sealed ones marked, and
its address; adding one with a bearer token or another header kept in the
store; testing it with its credential and listing its tools; granting them
to a team, project, org, person or key, written into that level's limits
beside its other grants and its rate and budget; revoking; changing;
replacing the credential; turning off and on; removing; and how a person
points an agent at the gateway's /mcp with a key of their own. English and
Turkish. The secret's field is named so the audit line redacts it.
The admin API's server merge and test are package functions now,
adminapi.MCPServerFrom and adminapi.TestMCPServer, shared by both.

For each layout modelplan.Options offers here — one card, tensor parallel
across a node's cards, llama.cpp's layer split, a pipeline across nodes on
a fabric — modelplan.GPUTokensPerSecond gives one reply's speed: the bytes
a token reads over each card's bandwidth, by its model name (a table, SXM
and PCIe apart), plus two all-reduces a layer for tensor parallel (8 us on
NVLink, 25 us and up on PCIe), turns between cards for a layer split, and
a hop per node over InfiniBand or RoCE for a pipeline. The explorer and a
repository's files show the fastest, with the layout; mixed classes are
judged class by class, FP8 on 8.9 cards only.
Calibrated on cuda01's Quadro RTX 6000 (672 GB/s): qwen3-vl-8b Q8, 8.7 GB,
62.1 tok/s measured, 59 estimated; Qwen3-Coder-30B-A3B Q4_K_M, 18.6 GB,
144 measured, which says a model of experts reads 1.6 times its active
share (ActiveShare now does, on the CPU too). Tensor parallel and fabrics
are not measured here.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Each agent measures its node's memory read rate when it starts: every CPU
sums a share of a buffer past any cache, a tenth of free memory at most,
the best of four passes, in a fraction of a second; reported in Host
(mem_bandwidth_gbs) and NodeView. A token on a CPU reads every weight it
uses once, so one reply's speed is about that rate over those bytes:
modelplan.CPUTokensPerSecond, 0.68 of the measured rate plus 5 ms a token,
calibrated on the PoC against llama.cpp's predicted_per_second (node01
24.9 GB/s, qwen2.5-1.5b: 14.5 measured, 14.7 estimated; node05 41.9 GB/s,
qwen2.5-14b: 3.3 and 3.2). A model of experts named …-A3B reads its active
part (ActiveShare).
The explorer shows it as CPU tok/s, at Q4_K_M on the fastest node that
holds the model; a repository's page gives it for each GGUF by its size.

Judged by the nodes as they are now, through modelplan.Options, the
planner that serving a model uses: GGUF at Q4_K_M from the parameter count,
safetensors at the size the registry's dtype breakdown gives (packed AWQ,
GPTQ and MXFP4 at four bits), FP8 only where a card has compute capability
8.9, MLX safetensors never. A picture model is judged against one card. A
cluster with cards asks the registry for safetensors too, a hundred at a
time; one without asks for GGUF only. The page says what it judged by: the
largest card, its capability, the most RAM on one node.
On a repository's page a file set no node holds is marked with what it
needs, against what the best node offers, and has no Fetch button.
Tried against the PoC's seven nodes and Hugging Face's trending hundred:
63 shown, the rest too big for one 24 GB Turing card or FP8.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A repository with neither GGUF nor safetensors (by the registry's summary
or its tags) is hidden under "runs here", which is ticked by default, and
counted with the architectures llama.cpp cannot load; unticked it is
listed. An open repository's pickle files are not offered, only counted,
and a repository of pickles only says to look for another version.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Python pickles (.bin, .pt, .pth, .ckpt, .pkl) run whatever they hold when
loaded, as the engine's user, on the node; that is how the malicious models
found on Hugging Face work. The node refuses such a source, or a mirror set
holding one, before fetching anything. A model added with one, or given
one, is refused, while one already in the catalog still loads and is
refused by its node with the same words. vLLM and SGLang downloading a
model by its id get --load-format safetensors. The mirror page marks the
file. allow_pickle: true on a model lets it through on purpose, carried to
the node in EngineProfile.allow_pickle.
BACKLOG M lists the rest: checksums against Hugging Face on every path,
its own scan, trusted publishers, engines without the internet, an eval
before an untrusted model serves.

A control plane that is also a node, serving the starter model and two
judges, needs about 10.5 GB: 3.5 for itself, 2 for the starter, 2 for each
judge, and one more because the scheduler counts whole gigabytes. On 8 GB
the install did every step and then had nowhere to run the starter. The
setup's checks now fail this machine's memory and name what it would serve,
and server init refuses before it installs anything, naming the flags that
leave those models off it. quick-install.md said 8 GB; it says 12.

llmgw's own extension for VS Code, plain JavaScript with no dependencies,
packed into a .vsix by the binary at /setup/vscode/llmgw.vsix with the
serving gateway's address in it, so it needs no build, no Node and no
marketplace. It registers llmgw as a language-model provider: the chat's
model picker, agent mode and any extension that asks VS Code for a model
get every chat model the key may use, sized and with tool and vision
capabilities as the catalog says, streamed, tool calls both ways.
VS Code is a tool on the account page's Connect your editor: a key, the
install command, and an Open in VS Code link that hands the key to the
extension's secret storage. The extension's Sign In opens the page with a
state of its own; a link without it is confirmed, the gateway named, since
it decides where code is sent.
Tested in VS Code 1.138 against the PoC: 27 models listed, an answer from
qwen2.5-0.5b-instruct, and qwen3-coder-30b calling a tool and using its
result (internal/vscodeext/e2e).

/install takes a reader from three bare Ubuntu machines to a first answer:
what each machine needs and the commands that check it, the release fetched
and its checksum checked, the eight setup screens, the system's state and
the console, and a first request with a key from the account page. Every
screen is from an install of v0.14.9 on three fresh VMs, recorded with tmux
and kept as terminal frames: the page shows them as text, and plays a
session back when asked, fetching it compressed from /install/cast/. The
administrator's password and the API key were masked before the recording
was kept, and a test fails if either shape reaches the page.
/about gains what llmgw now does beyond routing, and its install steps are
today's: the setup screens and node add, not onboard-node.sh and a model
file, with a link into the guide.

The errors other packages give a page (store, catalog, mirror) are

auth.ldap checks a username and password against the domain controllers
over LDAPS or StartTLS: found with a service account, checked by binding
as the person. Groups, nested ones included, give staff roles and places
in the tree. Accounts are tied to the objectGUID; the leader reads the
directory every 15 minutes, suspends whom it disabled or removed and
reinstates them after, and refuses a sync that would suspend most.
Entra ID sends no groups for someone in more than 200, only where to
fetch them; that was read as none and took an administrator's role away.
It is now left as it was, and logged. An account made by SCIM or OIDC
can be reinstated again.

Found by a three-machine install on fresh VMs. The second standby's run
asked for the floating address's interface with `ip route get <vip>`.
The machine already held the address, so that answered lo, and keepalived
would not start. The interface now comes from the route to the address's
network. Every cluster's VRRP router id was 51, so the PoC's two control
planes and the new three on one LAN each logged the other's adverts as an
invalid password; the id now comes from the address.
The Caddyfile, deploy/ha and install.md send clients to the control plane
whose /leader is 200, not /ready: /ready is 503 on a leader with no model
yet and would take the portal away with it. Setup no longer hides a key
file's path as if it were a password, and the starter's text no longer
says it runs elsewhere when this machine is a node.

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.

Five pages named /_static/pages.js outright, cached for a day, so a

The cluster and node pages swap their live part every few seconds, and the
forms inside it went with it: what was typed, an open choice, the focus.
Filling one in raced the clock. The swap now waits while a field in the
live part has the focus or a form in it has been typed into and not sent;
sending it, or leaving the page, ends that. The mirror page's reload
during a download goes through the same check instead of http-equiv.

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.

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.

A game sold in the EU cannot ship what a licence excluding the EU made. On
the profile page a person leaves out licences one by one, or by rule:
every licence forbidding commercial use, every licence granting nothing in
a region. The rules cover models added later. The choice reaches every
principal through the resolved limits, so permits() leaves such models out
of /v1/models, requests, jobs, fallbacks and the portal's pickers, and a
request for one is refused 403 licence_excluded saying which choice did.
Kept in user_excluded_licences (migration 0046), copied with the store and

/v1/openapi.json is the API clients use — OpenAI's endpoints, Anthropic's,
and what llmgw adds — in OpenAPI 3.1, generated from internal/clientapi's
route table by the generator the admin API's document comes from, now
told each document's title, server, token and error. A test reads the
router's mux.HandleFunc calls and refuses a route described and not
mounted, or mounted and not described. Asked for before there is a key,
so it needs none.
/docs/api shows it in Swagger UI 5.33.1 (Apache 2.0, served from the
gateway as the page's policy requires): Authorize takes a key, Try it out
sends to this gateway. Staff are offered the admin API's document too,
from /docs/api/admin.json, which nobody else is given.

/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,

The cookie that carries a sign-in across the provider was signed with a

/images offers the models that make pictures, and the chat no longer
offers them. Like the chat, the browser holds a session and never a key;
the page's request is rebuilt from its own fields and sent down the path
every /v1/images/generations request takes. Size, how many, seed, steps
and a negative prompt; each picture shown with its seed, a download link
and a way to make it again. Nothing is kept but the usage. The menu
offers the page while some model makes pictures.

It sat in localStorage under one fixed key, so the next person to sign in

Llama Guard 3 1B could not tell ordinary coding requests from harmful ones:
on the PoC it scored "continue" 0.51, "continue the code above" 0.89 and
"how do I kill all child processes in bash" 0.92 unsafe, against 0.97 to
1.00 for harmful requests, at Q4_K_M and Q8_0 alike, with its own template.
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.
- format qwen3guard: its prompt written out as its template writes it, for
requests and answers, and its Safe / Unsafe / Controversial verdict read;
controversial counts as the policy's judge.controversial says, safe by
default.
- judge.models: judges asked in turn, the first that answers deciding; a
failure is recorded against the judge that failed. guard judge use sets
the order, replacing categories none of the judges names.
- known judges (Qwen3Guard 0.6B/4B/8B, Llama Guard 1B/8B): guard judge
enable serves any of them, --gpu the 4B on the roomiest GPU class as a
standard model; the leader fetches and serves one a policy names that the
catalog lacks.
- server init installs qwen3guard-0.6b with the baseline's categories.
- a judge reads a long text by its start and end, which fit its context,
rather than overflowing it and refusing the request under fail: closed.

their hash in password_resets, good for an hour, a newer one replacing an

reset-link makes the link to hand over. Single sign-on accounts get none.

guard.enabled (unset is on) makes every policy check nothing while false,
live: llmgw ctl guard off/on set it in the cluster's settings, and ctl
status, ctl guard list and the guardrails page say when they are off.
A refusal by a judge names the hazard it saw - judge: S6,Specialized
Advice - and the verdict is kept with the request in a new usage column,
guard_rule, shown by ctl request, the request log and the guardrails page.
llmgw ctl guard judge ask has a judge read a text, past the cache, and shows
its raw answer and how it is read; the endpoint is kept out of the audit so
no text is recorded.

llmgw ctl guard judge status lists each judge model the policies ask:

problem on ctl status and the console's Overview.
A Llama Guard file served from the mirror page is added as a judge, under

Everything in server.yaml that is not one machine's own is now a versioned
document in the store (cluster_settings), the same on every control plane.
The first start against a store imports the file's cluster keys, with the
baseline guard policy when there is none; after that those keys in a file
are ignored, with a warning.
Each control plane polls the document's version and its own server.yaml's
hash. A change is validated and applied: guard live (Gate.Replace), anything
else by a graceful restart that systemd brings back, standbys first and the
leader 30s later. A version that does not load on a machine is not applied;
at start the newest one that loads is used, so a bad edit cannot keep every
control plane down.
llmgw ctl config show/get/set/unset/edit/history/rollback, the admin API
under /api/v1/settings, and the console's Settings screen, which layers the
store's document over the machine's file, write it. Commands beside the
control plane that read cluster keys (init, node add, server add, backup,
upgrade) read the layered configuration; init --bundle writes offline to
the store once it holds the settings.
A standby that becomes the leader re-reads models, engine choices and
facility holds from the store.
Retires appendGuardIfMissing: the import does it.
