The mapping is by `(build-type, platforms)` — see existing entries for the pattern. CI uses these prebuilt bases to skip the gRPC compile (~25–35 min cold). Local `make backends/<name>` ignores `builder-base-image` and uses the from-source path inside the Dockerfile, so you don't need quay access for local builds.

-## Bundling runtime shared libraries (`package.sh`)
-
-The final `Dockerfile.python` stage is `FROM scratch` — there is no system `libc`, no `apt`, no fallback library path. Only files explicitly copied from the builder stage end up in the backend image. That means any runtime `dlopen` your backend (or its Python deps) needs **must** be packaged into `${BACKEND}/lib/`.
-
-Pattern:
-
-1. Make sure the library is installed in the builder stage of `backend/Dockerfile.python` (add it to the top-level `apt-get install`).
-2. Drop a `package.sh` in your backend directory that copies the library — and its soname symlinks — into `$(dirname $0)/lib`. See `backend/python/vllm/package.sh` for a reference implementation that walks `/usr/lib/x86_64-linux-gnu`, `/usr/lib/aarch64-linux-gnu`, etc.
-3. `Dockerfile.python` already runs `package.sh` automatically if it exists, after `package-gpu-libs.sh`.
-4. `libbackend.sh` automatically prepends `${EDIR}/lib` to `LD_LIBRARY_PATH` at run time, so anything packaged this way is found by `dlopen`.
-
-How to find missing libs: when a Python module silently fails to register torch ops or you see `AttributeError: '_OpNamespace' '...' object has no attribute '...'`, run the backend image's Python with `LD_DEBUG=libs` to see which `dlopen` failed. The filename in the error message (e.g. `libnuma.so.1`) is what you need to package.
-
-To verify packaging works without trusting the host:
-
-```bash
-make docker-build-<backend>
-CID=$(docker create --entrypoint=/run.sh local-ai-backend:<backend>)
-docker cp $CID:/lib /tmp/check && docker rm $CID
-ls /tmp/check    # expect the bundled .so files + symlinks
-```
-
-Then boot it inside a fresh `ubuntu:24.04` (which intentionally does *not* have the lib installed) to confirm it actually loads from the backend dir.
-
-## Importer integration
-
-When you add a new backend, you MUST also make it importable via the model import form (`/import-model`). The import form dropdown is sourced dynamically from `GET /backends/known` — it reads the importer registry at `core/gallery/importers/importers.go`, so the steps below are the ONLY way to make your backend show up.
-
-Required steps:
-
-1. **If your backend has unambiguous detection signals** (unique file extension, HF `pipeline_tag`, unique repo name pattern, unique artefact like `modules.json`):
-   - Create an importer file at `core/gallery/importers/<backend>.go` following the Match/Import pattern in `llama-cpp.go`.
-   - Register it in `importers.go:defaultImporters` in **specificity order** — more specific detectors must appear BEFORE more generic ones (e.g. `sentencetransformers` before `transformers`, `stablediffusion-ggml` before `llama-cpp`, `vllm-omni` before `vllm`). First match wins.
-2. **If your backend is a drop-in replacement** (same artefacts as another backend, e.g. `ik-llama-cpp` and `turboquant` both consume GGUF the same way `llama-cpp` does):
-   - Do NOT create a new importer. Extend the existing importer's `Import()` to swap the emitted `backend:` field when `preferences.backend` matches. See `llama-cpp.go` for the pattern.
-3. **If your backend has no reliable auto-detect signal** (preference-only — e.g. `sglang`, `tinygrad`, `whisperx`):
-   - Do NOT create an importer. Instead add the backend name to the curated pref-only slice in `core/http/endpoints/localai/backend.go` that feeds `/backends/known`. A single line addition.
-4. **Always** add a table-driven test in `core/gallery/importers/importers_test.go` (Ginkgo/Gomega):
-   - Use a real public HuggingFace repo URI as the test fixture (existing tests already hit the live HF API — follow that pattern).
-   - Cover detection (auto-match without preferences), preference-override (explicit `backend:` in preferences wins), and — if the backend's modality has a common `pipeline_tag` but ambiguous artefacts — an ambiguity test asserting `errors.Is(err, importers.ErrAmbiguousImport)`.
-
-Rules of thumb:
-
-- When in doubt, lean pref-only. A wrong auto-detect is worse than a forced preference.
-- Never silently emit a modality mismatch (e.g. emit `llama-cpp` for a TTS repo because `.gguf` is present). Return `ErrAmbiguousImport` instead.
-- Registration order is the single most common source of bugs. Check by running `go test ./core/gallery/importers/...` — the existing suite will fail if you've shadowed a pre-existing detector.

-# Adding GGUF Models from HuggingFace to the Gallery
-
-When adding a GGUF model from HuggingFace to the LocalAI model gallery, follow this guide.
-
-## Gallery file
-
-All models are defined in `gallery/index.yaml`. Find the appropriate section (embedding models near other embeddings, chat models near similar chat models) and add a new entry.
-
-## Getting the SHA256
-
-GGUF files on HuggingFace expose their SHA256 via the `x-linked-etag` HTTP header. Fetch it with:
-
-```bash
-curl -sI "https://huggingface.co/<org>/<repo>/resolve/main/<filename>.gguf" | grep -i x-linked-etag
-```
-
-The value (without quotes) is the SHA256 hash. Example:
-
-```bash
-curl -sI "https://huggingface.co/ggml-org/embeddinggemma-300m-qat-q8_0-GGUF/resolve/main/embeddinggemma-300m-qat-Q8_0.gguf" | grep -i x-linked-etag
-# x-linked-etag: "6fa0c02a9c302be6f977521d399b4de3a46310a4f2621ee0063747881b673f67"
-```
-
-**Important**: Pay attention to exact filename casing — HuggingFace filenames are case-sensitive (e.g., `Q8_0` vs `q8_0`). Check the repo's file listing to get the exact name.
-
-## Entry format — Embedding models
-
-Embedding models use `gallery/virtual.yaml` as the base config and set `embeddings: true`:
-
-```yaml
-- name: "model-name"
-  url: github:mudler/LocalAI/gallery/virtual.yaml@master
-  urls:
-    - https://huggingface.co/<original-model-org>/<original-model-name>
-    - https://huggingface.co/<gguf-org>/<gguf-repo-name>
-  description: |
-    Short description of the model, its size, and capabilities.
-  tags:
-    - embeddings
-  overrides:
-    backend: llama-cpp
-    embeddings: true
-    parameters:
-      model: <filename>.gguf
-  files:
-    - filename: <filename>.gguf
-      uri: huggingface://<gguf-org>/<gguf-repo-name>/<filename>.gguf
-      sha256: <sha256-hash>
-```
-
-## Entry format — Chat/LLM models
-
-Chat models typically reference a template config (e.g., `gallery/gemma.yaml`, `gallery/chatml.yaml`) that defines the prompt format. Use YAML anchors (`&name` / `*name`) if adding multiple quantization variants of the same model:
-
-```yaml
-- &model-anchor
-  url: "github:mudler/LocalAI/gallery/<template>.yaml@master"
-  name: "model-name"
-  icon: https://example.com/icon.png
-  license: <license>
-  urls:
-    - https://huggingface.co/<org>/<model>
-    - https://huggingface.co/<gguf-org>/<gguf-repo>
-  description: |
-    Model description.
-  tags:
-    - llm
-    - gguf
-    - gpu
-    - cpu
-  overrides:
-    parameters:
-      model: <filename>-Q4_K_M.gguf
-  files:
-    - filename: <filename>-Q4_K_M.gguf
-      sha256: <sha256>
-      uri: huggingface://<gguf-org>/<gguf-repo>/<filename>-Q4_K_M.gguf
-```
-
-To add a variant (e.g., different quantization), use YAML merge:
-
-```yaml
-- !!merge <<: *model-anchor
-  name: "model-name-q8"
-  overrides:
-    parameters:
-      model: <filename>-Q8_0.gguf
-  files:
-    - filename: <filename>-Q8_0.gguf
-      sha256: <sha256>
-      uri: huggingface://<gguf-org>/<gguf-repo>/<filename>-Q8_0.gguf
-```
-
-## Available template configs
-
-Look at existing `.yaml` files in `gallery/` to find the right prompt template for your model architecture:
-
-- `gemma.yaml` — Gemma-family models (gemma, embeddinggemma, etc.)
-- `chatml.yaml` — ChatML format (many Mistral/OpenHermes models)
-- `deepseek.yaml` — DeepSeek models
-- `virtual.yaml` — Minimal base (good for embedding models that don't need chat templates)
-
-## Checklist
-
-1. **Find the GGUF file** on HuggingFace — note exact filename (case-sensitive)
-2. **Get the SHA256** using the `curl -sI` + `x-linked-etag` method above
-3. **Choose the right template** config from `gallery/` based on model architecture
-4. **Add the entry** to `gallery/index.yaml` near similar models
-5. **Set `embeddings: true`** if it's an embedding model
-6. **Include both URLs** — the original model page and the GGUF repo
-7. **Write a description** — mention model size, capabilities, and quantization type

 This guide covers how to add new API endpoints and properly integrate them with the auth/permissions system.
 
-> **Before you ship a new endpoint or capability surface**, re-read the [checklist at the bottom of this file](#checklist). LocalAI advertises its feature surface in several independent places — miss any one of them and clients/admins/UI won't know the endpoint exists.
-
 ## Architecture overview
 
 Authentication and authorization flow through three layers:
@@ -236,66 +234,6 @@ Use these HTTP status codes:
 
 If your endpoint should be tracked for usage (token counts, request counts), add the `usageMiddleware` to its middleware chain. See `core/http/middleware/usage.go` and how it's applied in `routes/openai.go`.
 
-## Advertising surfaces — where to register a new capability
-
-Beyond routing and auth, LocalAI publishes its capability surface in **four independent places**. When you add an endpoint — especially one introducing a net-new capability like a new media type or a new auth-gated feature — you must update every relevant surface. These aren't optional: missing them means the endpoint works but is invisible to clients, admins, and the UI.
-
-### 1. Swagger `@Tags` annotation (mandatory)
-
-Every handler needs a swagger block so the endpoint appears in `/swagger/index.html` and in the `/api/instructions` output. The `@Tags` value is what groups the endpoint into a capability area:
-
-```go
-// MyEndpoint does X.
-// @Summary Do X.
-// @Tags my-capability
-// @Param request body schema.MyRequest true "payload"
-// @Success 200 {object} schema.MyResponse "Response"
-// @Router /v1/my-endpoint [post]
-func MyEndpoint(...) echo.HandlerFunc { ... }
-```
-
-Use an existing tag when the endpoint extends an existing area (e.g. `audio`, `images`, `face-recognition`). Create a new tag only when the endpoint introduces a genuinely new capability surface — and in that case, also register it in step 2.
-
-After adding endpoints, regenerate the embedded spec so the runtime serves it:
-
-```bash
-make protogen-go         # ensures gRPC codegen is fresh first
-make swagger             # regenerates swagger/swagger.json
-```
-
-### 2. `/api/instructions` registry (for new capability areas)
-
-`core/http/endpoints/localai/api_instructions.go` defines `instructionDefs` — a lightweight, machine-readable index of capability areas that groups swagger endpoints by tag. It's the primary discovery surface for agents and SDKs ("what can this server do?").
-
-**When to update:** only when adding a new capability area (a new swagger tag). Existing-tag additions automatically surface without any change here.
-
-Add an entry to `instructionDefs`:
-
-```go
-{
-    Name:        "my-capability",             // URL segment at /api/instructions/my-capability
-    Description: "Short sentence describing the capability",
-    Tags:        []string{"my-capability"},   // must match swagger @Tags
-    Intro:       "Optional gotcha/context that isn't in the swagger descriptions (caveats, defaults, cross-references to other endpoints).",
-},
-```
-
-Also bump the expected-length count in `api_instructions_test.go` and add the name to the `ContainElements` assertion.
-
-### 3. `capabilities.js` symbol (for new model-config FLAG_* flags)
-
-If your feature needs a new `FLAG_*` usecase flag in `core/config/model_config.go` (so users can filter gallery models by it, and so `/v1/models` surfaces it), also declare the matching symbol in `core/http/react-ui/src/utils/capabilities.js`:
-
-```js
-export const CAP_MY_CAPABILITY = 'FLAG_MY_CAPABILITY'
-```
-
-React pages that want to filter the ModelSelector by capability import this symbol. Declare it even if you're not building the UI page yet — the declaration keeps the Go/JS vocabularies in sync.
-
-### 4. `docs/content/` (user-facing documentation)
-
-A new capability deserves its own page under `docs/content/features/`, plus cross-links from related features and an entry in `docs/content/whats-new.md`. See the pattern used by `face-recognition.md` / `object-detection.md`.

-## Companion: MCP admin tool surface
-
-**Required for admin endpoints.** Every new admin endpoint MUST be considered for the MCP admin tool surface — the REST API and the MCP tool catalog can drift silently otherwise, and both the LocalAI Assistant chat modality and the standalone `local-ai mcp-server` rely on `pkg/mcp/localaitools/` to mirror REST.
-
-Two outcomes are acceptable; one is not:
-
-- **Tool added.** The new endpoint is something an admin would manage conversationally (install, list, edit, toggle, upgrade). Follow the full checklist in [.agents/localai-assistant-mcp.md](localai-assistant-mcp.md): add a `LocalAIClient` interface method, implement it in both `inproc` and `httpapi`, register the tool with a `Tool*` constant, update the skill prompts, **and add the route to `toolToHTTPRoute` in `pkg/mcp/localaitools/coverage_test.go`**.
-- **Tool deliberately skipped.** The endpoint is internal/diagnostic and adding a chat path would be misleading. Document the decision in the PR description; no code action.
-- **Forgot.** This breaks the contract. The `TestToolHTTPRouteMappingComplete` test in `pkg/mcp/localaitools` is a partial guard (it checks every `Tool*` has a route mapping), but it does NOT detect new REST endpoints without a tool — that's still a process check on the PR author.
-
-**Add to the bottom of the checklist below**:
-- [ ] If admin: decided whether MCP coverage is needed; if yes, tool registered + map updated; if no, skip-reason in PR description.

-# CI Build Caching
-
-Container builds — both the root LocalAI image (`Dockerfile`) and the per-backend images (`backend/Dockerfile.*`) — share a registry-backed BuildKit cache plus a layered set of prebuilt base images. This file explains how the cache is laid out, what invalidates it, and how to bypass it.
-
-## Workflow surfaces
-
-| Workflow | Purpose | Triggers |
-|---|---|---|
-| `.github/workflows/backend.yml` | Backend container images on master | `push` to master + tags, weekly Sunday cron, `workflow_dispatch` |
-| `.github/workflows/backend_pr.yml` | Backend container images on PRs | `pull_request` |
-| `.github/workflows/backend_build.yml` | Reusable: builds one backend (one arch) by digest | `workflow_call` from above |
-| `.github/workflows/backend_merge.yml` | Reusable: assembles per-arch digests into a multi-arch manifest list | `workflow_call` |
-| `.github/workflows/backend_build_darwin.yml` | Reusable: macOS-native backend builds | `workflow_call` |
-| `.github/workflows/image.yml` / `image-pr.yml` | Root LocalAI image (push / PR) | push / PR |
-| `.github/workflows/image_build.yml` / `image_merge.yml` | Reusable: per-arch root-image build + merge | `workflow_call` |
-| `.github/workflows/base-images.yml` | Builds the prebuilt `base-grpc-*` builder bases | Saturdays 05:00 UTC cron, `workflow_dispatch`, master push touching `Dockerfile.base-grpc-builder`, `.docker/install-base-deps.sh`, `.docker/apt-mirror.sh`, or this workflow |
-
-The matrix that drives `backend.yml` / `backend_pr.yml` lives in **`.github/backend-matrix.yml`** (data-only YAML, not embedded in the workflow). `scripts/changed-backends.js` parses it, applies path-filter logic against the PR diff (PR events) or the GitHub Compare API (push events), and emits the filtered matrix plus a `merge-matrix` for backends with multiple per-arch entries.
-
-## Cache layout
-
-- **Cache registry**: `quay.io/go-skynet/ci-cache`
-- **One tag per matrix entry per arch**, derived from `tag-suffix` and `platform-tag`:
-  - Backend builds (`backend_build.yml`): `cache<tag-suffix>-<platform-tag>`
-    - e.g. `cache-cpu-faster-whisper-amd64`, `cache-cpu-faster-whisper-arm64`, `cache-gpu-nvidia-cuda-13-llama-cpp-amd64`
-  - Root image builds (`image_build.yml`): `cache-localai<tag-suffix>-<platform-tag>` (with a `-core` placeholder when `tag-suffix` is empty, so `cache-localai-core-amd64` for the core image)
-  - Pre-built base images (`base-images.yml`): `cache-base-grpc-<variant>` (one per `(BUILD_TYPE, arch)` permutation)
-- Each tag stores a multi-arch BuildKit cache manifest (`mode=max`), so every intermediate stage is re-usable, not just the final image.
-
-The per-arch suffix exists because amd64 and arm64 builds produce different intermediate content; sharing one cache key would thrash on every cross-arch rebuild.
-
-## Read/write semantics
-
-| Trigger | `cache-from` | `cache-to` |
-|---|---|---|
-| `push` to `master` / tag / cron / dispatch | yes | yes (`mode=max,ignore-error=true`) |
-| `pull_request` | yes | **no** |
-
-PR builds read master's warm cache but never write — this prevents PRs from polluting the shared cache with their experimental state. After merge, the master build for that matrix entry refreshes the cache.
-
-`ignore-error=true` on the write side means a transient quay push failure does not fail the build; the next master push retries.
-
-## Pre-built base images (`base-grpc-*`)
-
-The C++ backend Dockerfiles (`Dockerfile.{llama-cpp,ik-llama-cpp,turboquant}`) compile gRPC from source. On a cold build that's ~25–35 min before any LocalAI source compiles. To skip that on CI, `.github/workflows/base-images.yml` builds and pushes a set of pre-prepped builder bases:
-
-| Tag | Contents |
-|---|---|
-| `base-grpc-amd64` / `base-grpc-arm64` | Ubuntu 24.04 + apt build deps + protoc + cmake + gRPC at `/opt/grpc` |
-| `base-grpc-cuda-12-amd64` | the above + CUDA 12.8 toolkit |
-| `base-grpc-cuda-13-amd64` | the above + CUDA 13.0 toolkit (Ubuntu 22.04 base) |
-| `base-grpc-cuda-13-arm64` | the above + CUDA 13.0 sbsa toolkit (Ubuntu 24.04 base) |
-| `base-grpc-l4t-cuda-12-arm64` | JetPack r36.4.0 base (CUDA preinstalled, `SKIP_DRIVERS=true`) + gRPC |
-| `base-grpc-rocm-amd64` | rocm/dev-ubuntu-24.04:7.2.1 base + hipblas/hipblaslt/rocblas + gRPC |
-| `base-grpc-vulkan-amd64` / `base-grpc-vulkan-arm64` | Ubuntu 24.04 + Vulkan SDK 1.4.335 + gRPC |
-| `base-grpc-intel-amd64` | intel/oneapi-basekit:2025.3.2 base + gRPC |
-
-**Single source of truth**: the install logic for all 10 variants lives in `.docker/install-base-deps.sh`. Both `Dockerfile.base-grpc-builder` AND each variant Dockerfile's `builder-fromsource` stage bind-mount and execute the same script — so the prebuilt CI base and the local from-source path are bit-equivalent by construction.
-
-### How variant Dockerfiles consume the base
-
-`Dockerfile.{llama-cpp,ik-llama-cpp,turboquant}` are multi-target. Three stages plus a final aliasing stage:
-
-- `builder-fromsource` — `FROM ${BASE_IMAGE}` then runs `install-base-deps.sh` and the per-backend compile script. Used when `BUILDER_TARGET=builder-fromsource` (the default; local `make backends/<name>`).
-- `builder-prebuilt` — `FROM ${BUILDER_BASE_IMAGE}` (one of the prebuilt `base-grpc-*` tags) and runs only the per-backend compile script. Used when `BUILDER_TARGET=builder-prebuilt` (CI when the matrix entry sets `builder-base-image`).
-- `FROM ${BUILDER_TARGET} AS builder` — alias resolves the ARG-selected stage to a fixed name (BuildKit doesn't allow ARG expansion in `COPY --from=`).
-- `FROM scratch` + `COPY --from=builder ...package/. ./` — emits the final scratch image with just the package contents.
-
-BuildKit prunes the unreferenced builder stage, so each build only runs the path it needs. `backend_build.yml` derives `BUILDER_TARGET=builder-prebuilt` automatically when the matrix entry has a non-empty `builder-base-image`; otherwise it defaults to `builder-fromsource`.
-
-The matrix `(build-type, platforms)` → `builder-base-image` mapping for llama-cpp / ik-llama-cpp / turboquant entries:
-
-| `build-type` | `platforms` | tag |
-|---|---|---|
-| `''` | `linux/amd64` | `base-grpc-amd64` |
-| `''` | `linux/arm64` | `base-grpc-arm64` |
-| `cublas` cuda 12 | `linux/amd64` | `base-grpc-cuda-12-amd64` |
-| `cublas` cuda 13 | `linux/amd64` | `base-grpc-cuda-13-amd64` |
-| `cublas` cuda 13 | `linux/arm64` | `base-grpc-cuda-13-arm64` |
-| `cublas` cuda 12 + JetPack base | `linux/arm64` | `base-grpc-l4t-cuda-12-arm64` |
-| `hipblas` | `linux/amd64` | `base-grpc-rocm-amd64` |
-| `vulkan` | `linux/amd64` | `base-grpc-vulkan-amd64` |
-| `vulkan` | `linux/arm64` | `base-grpc-vulkan-arm64` |
-| `sycl_*` | `linux/amd64` | `base-grpc-intel-amd64` |
-
-### Bootstrap order when adding a new variant
-
-If you add a new entry to `base-images.yml`'s matrix, the new tag does not exist on quay until the workflow runs. To consume it from a variant entry safely, dispatch the base-images workflow on the branch first:
-
-```bash
-gh workflow run base-images.yml --ref <feature-branch>
-```
-
-Wait for the new variant to push, then merge the consumer change. Otherwise the consumer's CI fails with "image not found."
-
-## Per-arch native builds + manifest merge
-
-Multi-arch backends (and the core LocalAI image) build natively per arch instead of running both arches under QEMU emulation on a single x86 runner. The pattern:
-
-- The matrix has TWO entries per multi-arch backend, sharing the same `tag-suffix` but distinct `platforms` + `platform-tag` + `runs-on`. Example: `-cpu-faster-whisper` has one amd64 entry on `ubuntu-latest` and one arm64 entry on `ubuntu-24.04-arm`.
-- Each per-arch build pushes by **canonical digest only** (no tags) via `outputs: type=image,push-by-digest=true,name-canonical=true,push=true`. The digest is uploaded as an artifact named `digests<tag-suffix>-<platform-tag>` (or `digests-localai<...>` for root-image builds).
-- `scripts/changed-backends.js` detects shared `tag-suffix` and emits a `merge-matrix` output. `backend.yml` / `backend_pr.yml` have a `backend-merge-jobs` job that consumes it and calls `backend_merge.yml`.
-- `backend_merge.yml` downloads all matching digest artifacts and runs `docker buildx imagetools create` to publish the final tagged manifest list pointing at both per-arch digests. Same `docker/metadata-action` config as the original monolithic build, so consumers see no tag-shape change.
-- `image_merge.yml` is the equivalent for the root LocalAI image (`-core` placeholder when `tag-suffix` is empty so the artifact-name glob doesn't over-match across `core` and `gpu-vulkan`).
-
-**`provenance: false` is required on multi-registry digest pushes**: with the default `mode=max` provenance attestation, BuildKit bundles a per-registry attestation manifest into each registry's manifest list, making the resulting list digest diverge across registries. `steps.build.outputs.digest` only matches one of them and the merge step's `imagetools create <reg>@sha256:<digest>` lookup fails on the other. Setting `provenance: false` keeps the digest content-only and identical across registries.
-
-## Path filter on master push
-
-Both `backend.yml` (push) and `backend_pr.yml` (PR) generate their matrix dynamically through `scripts/changed-backends.js`:
-
-- **PR events**: paginated `pulls/{n}/files` API → filter the matrix to entries whose `dockerfile` path prefix matches the PR diff.
-- **Push events**: GitHub Compare API (`/repos/{owner}/{repo}/compare/{before}...{after}`) → same path-filter logic. Falls back to "run everything" on first-branch push (`event.before` zero), API truncation (≥300 changed files), missing API token, or any thrown error.
-- **Tag pushes**: `FORCE_ALL=true` is set from the workflow side (`startsWith(github.ref, 'refs/tags/')`) — releases rebuild every backend regardless of diff.
-- **Schedule / `workflow_dispatch`**: no `event.before`, falls through to "run everything" automatically.
-
-The Sunday 06:00 UTC cron on `backend.yml` exists specifically because path filtering can leave Python backends frozen on stale wheels. `DEPS_REFRESH` (below) only fires when the build actually runs, so an untouched Python backend would never re-resolve its unpinned deps. The weekly cron is the safety net.
-
-## The `DEPS_REFRESH` cache-buster (Python backends)
-
-Every Python backend goes through the shared `backend/Dockerfile.python`, which ends with:
-
-```dockerfile
-ARG DEPS_REFRESH=initial
-RUN cd /${BACKEND} && PORTABLE_PYTHON=true make
-```
-
-Most Python backends ship `requirements*.txt` files that **do not pin every transitive dep** (`torch`, `transformers`, `vllm`, `diffusers`, etc. are listed without a `==` pin, or with `>=` lower bounds only). With a warm BuildKit cache, the `make` layer hashes only on Dockerfile instructions + COPYed source — not on what `pip install` resolves at runtime. So a warm cache would ship the *first* version of `vllm` ever cached and never pick up upstream releases.
-
-`DEPS_REFRESH` defends against that:
-
-- `backend_build.yml` computes `date -u +%Y-W%V` (ISO week, e.g. `2026-W19`) before each build and passes it as a build-arg.
-- The `RUN ... make` layer's BuildKit hash now includes that string, so the layer invalidates **at most once per week**, automatically picking up newer wheels.
-- Within a week, builds stay warm.
-
-This applies only to `Dockerfile.python` because:
-- Go (`Dockerfile.golang`) pins versions in `go.mod` / `go.sum`.
-- Rust (`Dockerfile.rust`) pins via `Cargo.lock`.
-- C++ backends pin gRPC (`v1.65.0`) and llama.cpp at a specific commit; their inputs don't drift between rebuilds.
-
-### Adjusting the cadence
-
-Bump the format to daily (`+%Y-%m-%d`) or hourly (`+%Y-%m-%d-%H`) for faster refreshes. For one-shot rebuilds without changing the schedule, append a marker to the tag-suffix in the matrix or temporarily delete that backend's cache tag in quay.
-
-## ccache for C++ backend builds
-
-`Dockerfile.{llama-cpp,ik-llama-cpp,turboquant}` declare a BuildKit cache mount on `/root/.ccache`:
-
-```dockerfile
-RUN --mount=type=cache,target=/root/.ccache,id=<backend>-ccache-${TARGETARCH}-${BUILD_TYPE},sharing=locked \
-    bash /usr/local/sbin/compile.sh
-```
-
-The compile script exports `CMAKE_C/CXX/CUDA_COMPILER_LAUNCHER=ccache` so CMake threads ccache through gcc/g++/nvcc. `cache-to: type=registry,mode=max` exports the cache mount data into the registry cache, so subsequent builds restore it.
-
-On a `LLAMA_VERSION` bump, most translation units are byte-identical to the previous version's preprocessed source — ccache returns the previous `.o` and skips the real compile. Same for LocalAI source changes that don't actually touch llama.cpp's CMake inputs. Cache scope is per `(TARGETARCH, BUILD_TYPE)` so e.g. cublas-12 doesn't share with cublas-13 (their CUDA headers differ; cross-pollination would just be cache misses anyway).
-
-## Composite actions
-
-Two composite actions handle runner-side prep:
-
-- **`.github/actions/free-disk-space/action.yml`** — wraps `jlumbroso/free-disk-space@main` plus an explicit apt purge of dotnet/android/ghc/mono/etc. Reclaims ~6–10 GB on `ubuntu-latest`. No-op on self-hosted runners. Used by `backend_build.yml`, `image_build.yml`, `test.yml`, `tests-aio.yml`, etc.
-- **`.github/actions/setup-build-disk/action.yml`** — relocates Docker's data-root to `/mnt` on hosted X64 runners. GHA hosted `ubuntu-latest` ships ~75 GB of unused space at `/mnt`; combined with the free-disk-space cleanup this gives ~100 GB working space — enough for ROCm dev image + vLLM torch install + flash-attn intermediate layers. No-op on self-hosted and on non-X64 hosted runners. Used by `backend_build.yml`, `image_build.yml`, `base-images.yml`.
-
-Both actions run before any docker buildx step.
-
-## Concurrency
-
-All `backend.yml` / `image.yml` / `test.yml` / etc. workflows use:
-
-```yaml
-concurrency:
-  group: ci-<workflow>-${{ github.event.pull_request.number || github.sha }}-${{ github.repository }}
-  cancel-in-progress: ${{ github.event_name == 'pull_request' }}
-```
-
-- **PR events** group by PR number → newer pushes to the same PR cancel old runs (intended).
-- **Push events** group by `github.sha` → each master commit gets its own run; rapid-fire merges don't cancel each other (this was a real issue prior — two master pushes 11 seconds apart would cancel the first's CI).
-
-## Self-warming, no separate populator
-
-There is no cron job that pre-warms the BuildKit cache for individual backends. The production builds *are* the populators. The first master build of a given matrix entry pays the cold cost; subsequent same-entry master builds reuse everything that hasn't changed (apt installs, gRPC compile in the variant `builder-fromsource` stage or skipped entirely when consuming `base-grpc-*`, Python wheel installs, etc.). The base-images workflow's weekly cron is the closest thing to a populator and only refreshes the prebuilt builder bases.
-
-## Manually evicting cache
-
-To force a fully cold build for one backend or the whole image:
-
-```bash
-# Delete a single tag (requires quay credentials with admin on the repo)
-curl -X DELETE \
-  -H "Authorization: Bearer ${QUAY_TOKEN}" \
-  https://quay.io/api/v1/repository/go-skynet/ci-cache/tag/cache-gpu-nvidia-cuda-12-vllm-amd64
-
-# List all tags
-curl -s -H "Authorization: Bearer ${QUAY_TOKEN}" \
-  "https://quay.io/api/v1/repository/go-skynet/ci-cache/tag/?limit=100" | jq '.tags[].name'
-```
-
-Eviction is rarely needed in normal operation — `DEPS_REFRESH` handles weekly drift, source changes invalidate naturally, and `mode=max` keeps the cache scoped per matrix entry per arch so a stale tag never bleeds into a different build.
-
-## What the cache does **not** cover
-
-- The `free-disk-space` and `setup-build-disk` composite actions run on every job — these reclaim runner-state, not Docker layers, so BuildKit caches don't apply.
-- Intermediate artifacts of `Build (PR)` are not pushed anywhere — PRs only build for verification.
-- Darwin builds (see below) — macOS runners have no Docker daemon, so the registry-backed BuildKit cache cannot apply.
-
-## Darwin native caches
-
-`backend_build_darwin.yml` runs natively on `macOS-14` GitHub-hosted runners — there is no Docker, no BuildKit, no cross-job registry cache. Instead, the reusable workflow uses `actions/cache@v4` for four native caches that mirror the spirit of the Linux cache (warm by default, weekly refresh for unpinned Python deps, PRs read-only).
-
-| Cache | Path(s) | Key | Scope |
-|---|---|---|---|
-| Go modules + build | `~/go/pkg/mod`, `~/Library/Caches/go-build` | `go.sum` (managed by `actions/setup-go@v5` `cache: true`) | All darwin jobs |
-| Homebrew | `~/Library/Caches/Homebrew/downloads`, selected `/opt/homebrew/Cellar/*` | hash of `backend_build_darwin.yml` | All darwin jobs |
-| ccache (llama.cpp CMake) | `~/Library/Caches/ccache` | pinned `LLAMA_VERSION` from `backend/cpp/llama-cpp/Makefile` | `inputs.backend == 'llama-cpp'` only |
-| Python wheels (uv + pip) | `~/Library/Caches/pip`, `~/Library/Caches/uv` | `inputs.backend` + ISO week (`+%Y-W%V`) + hash of that backend's `requirements*.txt` | `inputs.lang == 'python'` only |
-
-Read/write semantics match the BuildKit cache: `actions/cache/restore` runs every time, `actions/cache/save` is gated on `github.event_name != 'pull_request'`. PRs read master's warm cache but never write back.
-
-The Python wheel cache uses the same ISO-week cache-buster as the Linux `DEPS_REFRESH` build-arg — same problem (unpinned `torch`/`mlx`/`diffusers`/`transformers` resolve to fresh wheels weekly), same ~one-cold-rebuild-per-week solution.
-
-The brew Cellar cache requires `HOMEBREW_NO_AUTO_UPDATE=1` and `HOMEBREW_NO_INSTALL_CLEANUP=1` (set as job-level env). Without those, `brew install` would mutate the very directories that were just restored, defeating the cache.
-
-**Force-link after cache restore**: `actions/cache` restores `/opt/homebrew/Cellar/*` but NOT the `/opt/homebrew/bin/*` symlinks. After a cache hit, `brew install` sees the Cellar entries and decides "already installed" without re-running its link step, leaving the formulas off PATH. The Dependencies step explicitly runs `brew link --overwrite` for every cached formula afterwards to ensure the symlinks exist.
-
-For ccache, the workflow exports `CMAKE_ARGS=… -DCMAKE_C_COMPILER_LAUNCHER=ccache -DCMAKE_CXX_COMPILER_LAUNCHER=ccache` via `$GITHUB_ENV` before running `make build-darwin-go-backend`. The Makefile in `backend/cpp/llama-cpp/` already forwards `CMAKE_ARGS` through to each variant build (`fallback`, `grpc`, `rpc-server`), so no script changes are needed. The three variants share most TUs, so ccache dedupes object files across them.
-
-`backend_build_darwin.yml` also has a llama-cpp-specific build-step branch that runs `make backends/llama-cpp-darwin` (the bespoke script that compiles three CMake variants and bundles dylibs via `otool`), distinct from the generic `make build-darwin-${lang}-backend` path. This was consolidated from a previously-bespoke top-level `llama-cpp-darwin` job in `backend.yml` so llama-cpp on Darwin honors the same path filter as the other 34 Darwin backends.
-
-### Cache budget on Darwin
-
-GitHub Actions caches are limited to 10 GB per repo. Steady-state worst case: ~800 MB Go cache + ~2 GB brew Cellar + up to 2 GB ccache + ~1.5 GB × 5 python backends. If the cap is hit, prefer collapsing the per-backend Python keys into a shared `pyenv-darwin-shared-<week>` key (accepts more cross-backend churn for a smaller footprint) before reducing other caches.
-
-## Self-hosted runners
-
-`.github/backend-matrix.yml` has zero references to `arc-runner-set` or `bigger-runner` — all backends run on GHA free-tier hosted runners (`ubuntu-latest` for amd64, `ubuntu-24.04-arm` for arm64 native, `macos-14` for Darwin). The migration off self-hosted relied on the per-arch native split (no QEMU emulation) plus `setup-build-disk`'s `/mnt` relocation (~100 GB working space, enough for ROCm dev image + vLLM/torch installs).
-
-One residual self-hosted reference remains in `test-extra.yml` (`tests-vibevoice-cpp-grpc-transcription` uses `bigger-runner` for the 30s JFK-decode timeout headroom). That's a separate concern.
-
-## Touching the cache pipeline
-
-When changing `image_build.yml`, `backend_build.yml`, any of the `backend/Dockerfile.*` files, `Dockerfile.base-grpc-builder`, `.docker/install-base-deps.sh`, `.docker/<backend>-compile.sh`, or `scripts/changed-backends.js`:
-
-1. **Don't drop `DEPS_REFRESH=...` from the build-args** without a replacement strategy (lockfiles, pinned requirements). Otherwise master will silently freeze on whichever versions were cached at the time.

-
-All Go tests — including backend tests — must use [Ginkgo](https://onsi.github.io/ginkgo/) (v2) with Gomega matchers, not the stdlib `testing` package with `t.Run` / `t.Errorf`. A test file should register a suite with `RegisterFailHandler(Fail)` in a `TestXxx(t *testing.T)` bootstrap and use `Describe`/`Context`/`It` blocks for the actual cases. Look at any existing `*_test.go` under `core/` or `pkg/` for a template.
-
-Do not mix styles within a package. If you are extending tests in a package that already uses Ginkgo, keep using Ginkgo. If you find stdlib-style Go tests in the tree, treat them as tech debt to be migrated rather than as a pattern to follow.
-
-This is enforced by `golangci-lint` via the `forbidigo` linter (see `.golangci.yml`); calls like `t.Errorf` / `t.Fatalf` / `t.Run` / `t.Skip` / `t.Logf` are flagged. Run `make lint` locally before submitting; the same check runs in CI (`.github/workflows/lint.yml`).

-# LocalAI Assistant — admin MCP server
-
-This document is the contract for **anyone** (human or AI agent) touching LocalAI's admin REST surface, the in-process MCP server that wraps it, or the embedded skill prompts that teach the assistant how to use it. Read this before adding/removing/renaming admin endpoints, MCP tools, or skill recipes.
-
-## What this feature is
-
-`pkg/mcp/localaitools/` is a public Go package that exposes LocalAI's admin/management surface as an MCP server. It is used in two ways:
-
-1. **In-process**: when an admin opens a chat with `metadata.localai_assistant=true`, the chat handler injects the in-memory MCP server (paired `net.Pipe()` transport, no HTTP loopback) so the LLM can install models, manage backends and edit configs by chatting.
-2. **Standalone**: the `local-ai mcp-server --target=…` subcommand serves the same MCP server over stdio, talking HTTP to a remote LocalAI instance.
-
-The two modes share **all** tool definitions and skill prompts. They differ only in their `LocalAIClient` implementation (`inproc/` calls services directly; `httpapi/` calls REST).
-
-## The three things you must keep in sync
-
-When you change LocalAI's admin surface, three layers must stay aligned:
-
-1. **REST endpoint** in `core/http/endpoints/localai/*.go`.
-2. **MCP tool registration** in `pkg/mcp/localaitools/tools_*.go`, plus a method on `LocalAIClient` (in `client.go`) and implementations in both `inproc/client.go` **and** `httpapi/client.go`.
-3. **Skill prompt** under `pkg/mcp/localaitools/prompts/skills/*.md` — the markdown that teaches the LLM how to use the new tool. If the new tool fits an existing recipe, update that recipe; otherwise add a new file.
-
-If you ship a REST endpoint without (2) and (3), conversational admins won't see the feature.
-
-## Checklist for adding a new admin endpoint
-
-- [ ] REST endpoint exists in `core/http/endpoints/localai/*.go` and is gated by `auth.RequireAdmin()` in `core/http/routes/localai.go`.
-- [ ] `LocalAIClient` interface in `pkg/mcp/localaitools/client.go` has a method covering the new operation.
-- [ ] DTOs added/updated in `pkg/mcp/localaitools/dto.go` (JSON-tagged; never expose raw service types).
-- [ ] `inproc/client.go` implements the new method by calling the service directly (not via HTTP loopback).
-- [ ] `httpapi/client.go` implements the new method by calling the REST endpoint.
-- [ ] Tool registration added in the appropriate `pkg/mcp/localaitools/tools_*.go`. Mutating tools must reference safety rule 1 in the description.
-- [ ] If the tool is mutating, ensure `Options{DisableMutating: true}` skips it (mirror the pattern in `tools_models.go`).
-- [ ] Skill prompt added or updated under `pkg/mcp/localaitools/prompts/skills/`. The prompt must instruct the LLM when to call the tool, what to ask the user first, and what to do on error.
-- [ ] Tests:
-   - `pkg/mcp/localaitools/server_test.go` adds the tool name to `expectedFullCatalog` and `expectedReadOnlyCatalog` (if read-only).
-   - Tool dispatch is added to `TestEachToolDispatchesToClient`.
-   - `pkg/mcp/localaitools/httpapi/client_test.go` covers the new HTTP path.
-
-## Adding a new skill recipe (no new tool)
-
-Sometimes you want to teach the LLM a new pattern that uses existing tools. Drop a markdown file under `pkg/mcp/localaitools/prompts/skills/<verb>_<noun>.md`. The file is automatically embedded by `//go:embed` and assembled into the system prompt in lexicographic order. No Go changes needed.
-
-Conventions:
-- Filename: `<verb>_<noun>.md` (e.g. `install_chat_model.md`, `upgrade_backend.md`).
-- First line: `# Skill: <Title Case description>`.
-- Number the steps. Reference exact tool names in backticks.
-- If the skill mutates state, remind the LLM to confirm with the user.
-
-## Code conventions
-
-These rules guard against the magic-literal drift that surfaced in the first audit. Do not re-introduce bare strings.
-
-- **Tool names** always come from the `Tool*` constants in `pkg/mcp/localaitools/tools.go`. Tool registrations, the test catalog (`server_test.go`'s `expectedFullCatalog` / `expectedReadOnlyCatalog`), and dispatch tables reference the constants. The embedded skill prompts under `prompts/` keep bare strings — that's the one allowed exception, and `TestPromptsContainSafetyAnchors` enforces alignment.
-- **Toggle/pin actions** use the `modeladmin.Action` type (`pkg/mcp/localaitools` and `core/services/modeladmin`). Use `ActionEnable`/`ActionDisable`/`ActionPin`/`ActionUnpin`; never bare `"enable"`/`"pin"` strings.
-- **Capability tags** for `list_installed_models` use the `localaitools.Capability` type (`capability.go`). The `LocalAIClient.ListInstalledModels` interface takes a typed `Capability`, and the `inproc` switch only accepts canonical values (`"embed"`/`"embedding"` are not aliases — only `CapabilityEmbeddings`).
-- **HTTP error checks** in `httpapi.Client` use `errors.Is(err, ErrHTTPNotFound)`, not substring matches on `err.Error()`. The typed `*HTTPError` carries `StatusCode` and `Body`; add new sentinel errors as needed rather than re-introducing string matching.
-- **Channel sends** to `GalleryService.ModelGalleryChannel` / `BackendGalleryChannel` from inproc clients MUST select on `ctx.Done()` so a cancelled chat completion releases the goroutine. See `inproc.sendModelOp` / `sendBackendOp`.
-- **Disk writes** of model config YAML go through `modeladmin.writeFileAtomic` (temp file + `os.Rename`). `os.WriteFile` truncates on crash and corrupts the model.
-- **MCP server lifecycle**: every initialised holder MUST register `Close()` with `signals.RegisterGracefulTerminationHandler`. The standalone `mcp-server` CLI uses `signal.NotifyContext` to honour SIGINT/SIGTERM.

-
-## Why two clients
-
-The in-process MCP server runs inside the same LocalAI binary that serves chat. Going over HTTP loopback would (a) require minting a synthetic admin API key for the server to authenticate against itself, (b) double-marshal every tool dispatch, and (c) lose access to in-process channels (e.g. `GalleryService.ModelGalleryChannel` for streaming install progress). So in-process uses `inproc.Client`. The standalone stdio CLI talks to a *remote* LocalAI; HTTP is the only option, so it uses `httpapi.Client`. Both implement the same `LocalAIClient` interface, and the parity test in `pkg/mcp/localaitools/parity_test.go` (when present) keeps their output equivalent.
-
-## Why prompt-enforced confirmation, not code gates
-
-The user chose KISS. Every mutating tool has a safety rule (`prompts/10_safety.md` rule 1) that requires the LLM to summarise the action and wait for explicit user confirmation before calling it. There is no `plan_*`/`apply_*` two-step in code. If you add a mutating tool, do **not** add per-tool confirmation logic in Go — instead, list the new tool name in `prompts/10_safety.md` so the LLM knows it falls under the confirmation rule.
-
-## Distributed mode
-
-The in-memory MCP server runs only on the head node (where the chat handler runs). `inproc.Client` wraps services that are already distributed-aware (`GalleryService` coordinates with workers; `ListNodes` reads the NATS-populated registry). No NATS routing of MCP tools — the admin surface lives on the head, period.

-# Working on the SGLang Backend
-
-The SGLang backend lives at `backend/python/sglang/backend.py` (async gRPC). It wraps SGLang's `Engine` (`sglang.srt.entrypoints.engine.Engine`) and translates LocalAI's gRPC `PredictOptions` into SGLang sampling params + outputs into `Reply.chat_deltas`. Structurally it mirrors `backend/python/vllm/backend.py` — keep them shaped the same so changes in one have an obvious analog in the other.
-
-## `engine_args` is the universal escape hatch
-
-A small fixed set of fields on `ModelOptions` is mapped to typed SGLang kwargs in `LoadModel` (model, quantization, load_format, gpu_memory_utilization → mem_fraction_static, trust_remote_code, enforce_eager → disable_cuda_graph, tensor_parallel_size → tp_size, max_model_len → context_length, dtype). **Everything else** flows through the `engine_args:` YAML map.
-
-Validation happens in `_apply_engine_args`. Keys are checked against `dataclasses.fields(ServerArgs)` (`sglang.srt.server_args.ServerArgs` is a flat `@dataclass` with ~380 fields). Unknown keys raise `ValueError` at LoadModel time with a `difflib.get_close_matches` suggestion — same shape as the vLLM backend.
-
-**Precedence:** typed `ModelOptions` fields populate `engine_kwargs` first, then `engine_args` overrides them. So a YAML that sets both `gpu_memory_utilization: 0.9` and `engine_args.mem_fraction_static: 0.5` ends up at `0.5`. Document this when answering "why didn't my YAML field stick?".
-
-**ServerArgs is flat.** Unlike vLLM, where speculative decoding is nested under `engine_args.speculative_config: {...}`, SGLang exposes flat top-level fields: `speculative_algorithm`, `speculative_draft_model_path`, `speculative_num_steps`, `speculative_eagle_topk`, `speculative_num_draft_tokens`, `speculative_dflash_block_size`, etc. There is no `speculative_config:` dict. Same goes for compilation, kv-transfer, attention — all flat.
-
-The canonical reference is `python/sglang/srt/server_args.py:ServerArgs` (line ~304). When SGLang adds new flags, no LocalAI code change is needed — they're automatically available via `engine_args:`. The validator picks them up because it introspects the live dataclass.
-
-## Speculative decoding cheatsheet
-
-`--speculative-algorithm` accepts `EAGLE`, `EAGLE3`, `NEXTN`, `STANDALONE`, `NGRAM`, `DFLASH`. `NEXTN` is silently rewritten to `EAGLE` in `ServerArgs.__post_init__` (`server_args.py:3286-3287`). MTP (Multi-Token Prediction) is the same EAGLE path with `num_steps=1, eagle_topk=1, num_draft_tokens=2` against a target whose architecture has multi-token heads (e.g. MiMo-7B-RL, DeepSeek-V3-MTP).
-
-| Algorithm | Drafter requirement | Gallery demo target | Gallery demo drafter |
-|-----------|--------------------|---------------------|----------------------|
-| `NEXTN` / `EAGLE` (MTP) | Assistant drafter or built-in heads | google/gemma-4-E2B-it, google/gemma-4-E4B-it | google/gemma-4-E2B-it-assistant, google/gemma-4-E4B-it-assistant |
-| `EAGLE3` | EAGLE3 draft head | (no gallery entry yet) | e.g. jamesliu1/sglang-EAGLE3-Llama-3.1-Instruct-8B |
-| `DFLASH` | Block-diffusion drafter | (no gallery entry yet) | e.g. z-lab/Qwen3-4B-DFlash-b16 |
-| `STANDALONE` | Smaller LLM as drafter | (no gallery entry yet) | any smaller chat-tuned LLM in the same family |
-| `NGRAM` | None — uses prefix history | (no gallery entry yet) | n/a |
-
-The Gemma 4 demos use `mem_fraction_static: 0.85` (cookbook default) and the cookbook's `num_steps=5, num_draft_tokens=6, eagle_topk=1` parameters. Other algorithms are reachable from any user YAML via `engine_args:` but don't have shipped demos yet — that's a deliberate gallery scope choice, not a backend limitation.
-
-Gemma 4 support requires sglang built from a commit that includes [PR #21952](https://github.com/sgl-project/sglang/pull/21952). LocalAI's pinned release for cublas12 / cublas13 includes it. The `l4t13` (JetPack 7 / sbsa cu130) build floors at `sglang>=0.5.0` because the `pypi.jetson-ai-lab.io` mirror still ships only `0.5.1.post2` as of 2026-05-06 — Gemma 4 / MTP recipes are therefore not available on l4t13 until that mirror catches up. `backend.py` keeps backward compat with the 0.5.x → 0.5.11 `SamplingParams.seed` → `sampling_seed` rename via runtime detection.
-
-Compatibility caveats per the SGLang docs: DFLASH and NGRAM are incompatible with `enable_dp_attention`; DFLASH requires `pp_size == 1`; STANDALONE is incompatible with `enable_dp_attention`; NGRAM is CUDA-only and disables the overlap scheduler.
-
-### `mem_fraction_static` + quantization + MTP on consumer GPUs
-
-When combining online weight quantization (`engine_args.quantization: fp8` / `awq` / etc.) with built-in-head MTP (`speculative_algorithm: EAGLE`/`NEXTN`) on a tight VRAM budget, sglang's default `mem_fraction_static: 0.85` will OOM during draft-worker init. The reason: sglang quantizes the **target** model's transformer blocks but loads the **MTP draft worker's vocab embedding** at the source dtype (typically bf16). For a 7 B-class model with a 150k-token vocab × 4096 hidden, that's another ~1.2 GiB allocated *after* the static pool is reserved. At 0.85 fraction on a 16 GB card there's no room left.
-
-Workaround: drop `mem_fraction_static` to ~0.7 so the post-static heap can absorb the MTP embedding alloc + CUDA graph private pools. Verified end-to-end on MiMo-7B-RL + fp8 + MTP on a 16 GB RTX 5070 Ti (`gallery/sglang-mimo-7b-mtp.yaml`) at ~88 tok/s. Models with larger vocabs or more MTP layers (e.g. DeepSeek-V3-MTP) need an even smaller fraction.
-
-This isn't documented anywhere upstream as of 2026-05-06 — the SGLang Gemma 4 cookbook uses 0.85 because their MTP path doesn't go through `eagle_worker_v2.py` for an embedding-bearing draft module. Don't blanket-apply 0.7 across all sglang YAMLs; only when MTP-with-built-in-heads + quantization combine.
-
-## Tool-call and reasoning parsers stay on `Options[]`
-
-ServerArgs has `tool_call_parser` and `reasoning_parser` fields, and the backend does pass them through to `Engine` so SGLang's own HTTP/OAI surface keeps working. But for the **LocalAI** request path the backend constructs fresh per-request parser instances in `_make_parsers` (`backend.py:286`) because the parsers are stateful — the streaming and non-streaming paths each need their own.
-
-So the user-facing knob stays on `Options[]`:
-
-```yaml
-options:
-  - tool_parser:hermes
-  - reasoning_parser:deepseek_r1
-```
-
-Putting these in `engine_args:` will set them on `ServerArgs` but the LocalAI-level streaming `ChatDelta` will not pick them up. Don't recommend that path.
-
-## What's missing today (out of scope, but worth tracking)
-
-- `core/config/hooks_sglang.go` — there is no SGLang equivalent of `hooks_vllm.go`. The vLLM hook auto-selects parsers for known model families from `parser_defaults.json` and seeds production engine_args defaults. A symmetric hook for SGLang could reuse the same `parser_defaults.json` (the SGLang parser names are different but the family detection is shared) and seed defaults like `enable_metrics: true` or attention-backend choices.
-- `core/gallery/importers/sglang.go` — vLLM has an importer that resolves model architecture → parser defaults at gallery-import time. A matching importer for SGLang would let `local-ai install` populate sensible parsers automatically.
-
-These should be a follow-up PR, not a blocker for the engine_args feature.

-# Working on the vLLM Backend
-
-The vLLM backend lives at `backend/python/vllm/backend.py` (async gRPC) and the multimodal variant at `backend/python/vllm-omni/backend.py` (sync gRPC). Both wrap vLLM's `AsyncLLMEngine` / `Omni` and translate the LocalAI gRPC `PredictOptions` into vLLM `SamplingParams` + outputs into `Reply.chat_deltas`.
-
-This file captures the non-obvious bits — most of the bring-up was a single PR (`feat/vllm-parity`) and the things below are easy to get wrong.
-
-## Tool calling and reasoning use vLLM's *native* parsers
-
-Do not write regex-based tool-call extractors for vLLM. vLLM ships:
-
-- `vllm.tool_parsers.ToolParserManager` — 50+ registered parsers (`hermes`, `llama3_json`, `llama4_pythonic`, `mistral`, `qwen3_xml`, `deepseek_v3`, `granite4`, `openai`, `kimi_k2`, `glm45`, …)
-- `vllm.reasoning.ReasoningParserManager` — 25+ registered parsers (`deepseek_r1`, `qwen3`, `mistral`, `gemma4`, …)
-
-Both can be used standalone: instantiate with a tokenizer, call `extract_tool_calls(text, request=None)` / `extract_reasoning(text, request=None)`. The backend stores the parser *classes* on `self.tool_parser_cls` / `self.reasoning_parser_cls` at LoadModel time and instantiates them per request.
-
-**Selection:** vLLM does *not* auto-detect parsers from model name — neither does the LocalAI backend. The user (or `core/config/hooks_vllm.go`) must pick one and pass it via `Options[]`:
-
-```yaml
-options:
-  - tool_parser:hermes
-  - reasoning_parser:qwen3
-```
-
-Auto-defaults for known model families live in `core/config/parser_defaults.json` and are applied:
-- at gallery import time by `core/gallery/importers/vllm.go`
-- at model load time by the `vllm` / `vllm-omni` backend hook in `core/config/hooks_vllm.go`
-
-User-supplied `tool_parser:`/`reasoning_parser:` in the config wins over defaults — the hook checks for existing entries before appending.
-
-**When to update `parser_defaults.json`:** any time vLLM ships a new tool or reasoning parser, or you onboard a new model family that LocalAI users will pull from HuggingFace. The file is keyed by *family pattern* matched against `normalizeModelID(cfg.Model)` (lowercase, org-prefix stripped, `_`→`-`). Patterns are checked **longest-first** — keep `qwen3.5` before `qwen3`, `llama-3.3` before `llama-3`, etc., or the wrong family wins. Add a covering test in `core/config/hooks_test.go`.
-
-**Sister file — `core/config/inference_defaults.json`:** same pattern but for sampling parameters (temperature, top_p, top_k, min_p, repeat_penalty, presence_penalty). Loaded by `core/config/inference_defaults.go` and applied by `ApplyInferenceDefaults()`. The schema is `map[string]float64` only — *strings don't fit*, which is why parser defaults needed their own JSON file. The inference file is **auto-generated from unsloth** via `go generate ./core/config/` (see `core/config/gen_inference_defaults/`) — don't hand-edit it; instead update the upstream source or regenerate. Both files share `normalizeModelID()` and the longest-first pattern ordering.
-
-**Constructor compatibility gotcha:** the abstract `ToolParser.__init__` accepts `tools=`, but several concrete parsers (Hermes2ProToolParser, etc.) override `__init__` and *only* accept `tokenizer`. Always:
-
-```python
-try:
-    tp = self.tool_parser_cls(self.tokenizer, tools=tools)
-except TypeError:
-    tp = self.tool_parser_cls(self.tokenizer)
-```
-
-## ChatDelta is the streaming contract
-
-The Go side (`core/backend/llm.go`, `pkg/functions/chat_deltas.go`) consumes `Reply.chat_deltas` to assemble the OpenAI response. For tool calls to surface in `chat/completions`, the Python backend **must** populate `Reply.chat_deltas[].tool_calls` with `ToolCallDelta{index, id, name, arguments}`. Returning the raw `<tool_call>...</tool_call>` text in `Reply.message` is *not* enough — the Go regex fallback exists for llama.cpp, not for vllm.
-
-Same story for `reasoning_content` — emit it on `ChatDelta.reasoning_content`, not as part of `content`.
-
-## Message conversion to chat templates
-
-`tokenizer.apply_chat_template()` expects a list of dicts, not proto Messages. The shared helper in `backend/python/common/vllm_utils.py` (`messages_to_dicts`) handles the mapping including:
-
-- `tool_call_id` and `name` for `role="tool"` messages
-- `tool_calls` JSON-string field → parsed Python list for `role="assistant"`
-- `reasoning_content` for thinking models
-
-Pass `tools=json.loads(request.Tools)` and (when `request.Metadata.get("enable_thinking") == "true"`) `enable_thinking=True` to `apply_chat_template`. Wrap in `try/except TypeError` because not every tokenizer template accepts those kwargs.
-
-## CPU support and the SIMD/library minefield
-
-vLLM publishes prebuilt CPU wheels at `https://github.com/vllm-project/vllm/releases/...`. The pin lives in `backend/python/vllm/requirements-cpu-after.txt`.
-
-**Version compatibility — important:** newer vllm CPU wheels (≥ 0.15) declare `torch==2.10.0+cpu` as a hard dep, but `torch==2.10.0` only exists on the PyTorch test channel and pulls in an incompatible `torchvision`. Stay on **`vllm 0.14.1+cpu` + `torch 2.9.1+cpu`** until both upstream catch up. Bumping requires verifying torchvision/torchaudio match.
-
-`requirements-cpu.txt` uses `--extra-index-url https://download.pytorch.org/whl/cpu`. `install.sh` adds `--index-strategy=unsafe-best-match` for the `cpu` profile so uv resolves transformers/vllm from PyPI while pulling torch from the PyTorch index.
-
-**SIMD baseline:** the prebuilt CPU wheel is compiled with AVX-512 VNNI/BF16. On a CPU without those instructions, importing `vllm.model_executor.models.registry` SIGILLs at `_run_in_subprocess` time during model inspection. There is no runtime flag to disable it. Workarounds:
-
-1. **Run on a host with the right SIMD baseline** (default — fast)
-2. **Build from source** with `FROM_SOURCE=true` env var. Plumbing exists end-to-end:
-   - `install.sh` hides `requirements-cpu-after.txt`, runs `installRequirements` for the base deps, then clones vllm and `VLLM_TARGET_DEVICE=cpu uv pip install --no-deps .`
-   - `backend/Dockerfile.python` declares `ARG FROM_SOURCE` + `ENV FROM_SOURCE`
-   - `Makefile` `docker-build-backend` macro forwards `--build-arg FROM_SOURCE=$(FROM_SOURCE)` when set
-   - Source build takes 30–50 minutes — too slow for per-PR CI but fine for local.
-
-**Runtime shared libraries:** vLLM's `vllm._C` extension `dlopen`s `libnuma.so.1` at import time. If missing, the C extension silently fails and `torch.ops._C_utils.init_cpu_threads_env` is never registered → `EngineCore` crashes on `init_device` with:
-
-```
-AttributeError: '_OpNamespace' '_C_utils' object has no attribute 'init_cpu_threads_env'
-```
-
-`backend/python/vllm/package.sh` bundles `libnuma.so.1` and `libgomp.so.1` into `${BACKEND}/lib/`, which `libbackend.sh` adds to `LD_LIBRARY_PATH` at run time. The builder stage in `backend/Dockerfile.python` installs `libnuma1`/`libgomp1` so package.sh has something to copy. Do *not* assume the production host has these — backend images are `FROM scratch`.
-
-## Backend hook system (`core/config/backend_hooks.go`)
-
-Per-backend defaults that used to be hardcoded in `ModelConfig.Prepare()` now live in `core/config/hooks_*.go` files and self-register via `init()`:
-
-- `hooks_llamacpp.go` → GGUF metadata parsing, context size, GPU layers, jinja template
-- `hooks_vllm.go` → tool/reasoning parser auto-selection from `parser_defaults.json`
-
-Hook keys:
-- `"llama-cpp"`, `"vllm"`, `"vllm-omni"`, … — backend-specific
-- `""` — runs only when `cfg.Backend` is empty (auto-detect case)
-- `"*"` — global catch-all, runs for every backend before specific hooks
-
-Multiple hooks per key are supported and run in registration order. Adding a new backend default:

-## The `Messages.ToProto()` fields you need to set
-
-`core/schema/message.go:ToProto()` must serialize:
-- `ToolCallID` → `proto.Message.ToolCallId` (for `role="tool"` messages — links result back to the call)
-- `Reasoning` → `proto.Message.ReasoningContent`
-- `ToolCalls` → `proto.Message.ToolCalls` (JSON-encoded string)
-
-These were originally not serialized and tool-calling conversations broke silently — the C++ llama.cpp backend reads them but always got empty strings. Any new field added to `schema.Message` *and* `proto.Message` needs a matching line in `ToProto()`.

-description: |
-  Reconfigure the GitHub Actions runner's Ubuntu apt sources to use an
-  alternate mirror, and emit the effective URLs as outputs so callers can
-  forward them as Docker build-args.
-
-  Two mirror profiles depending on where the runner lives, because the
-  best mirror differs by network:
-
-    * github-hosted runners run on Azure, so they default to the
-      Azure-hosted Ubuntu mirror (lowest latency, same VPC).
-    * self-hosted runners (arc-runner-set, bigger-runner, ...) typically
-      cannot route to azure.archive.ubuntu.com, so they default to the
-      kernel.org mirror, which is publicly reachable from anywhere.
-
-  Pass an empty string to either input to skip the rewrite for that
-  profile and keep upstream archive.ubuntu.com / ports.ubuntu.com.
-

-              run will propose this model again (useful if the entry needs

-            - `/gallery-agent blacklist` — close this PR and permanently
-              prevent the gallery agent from ever reproposing this model.
-
-            Plain "Close" (without a command) is treated as a no-op: the

-LocalAI follows the Linux kernel project's [guidelines for AI coding assistants](https://docs.kernel.org/process/coding-assistants.html). Before submitting AI-assisted code, read [.agents/ai-coding-assistants.md](.agents/ai-coding-assistants.md). Key rules:
-
-- **No `Signed-off-by` from AI.** Only the human submitter may sign off on the Developer Certificate of Origin.
-- **No `Co-Authored-By: <AI>` trailers.** The human contributor owns the change.
-- **Use an `Assisted-by:` trailer** to attribute AI involvement. Format: `Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]`.
-- **The human submitter is responsible** for reviewing, testing, and understanding every line of generated code.

 ## Quick Reference
 
@@ -37,7 +20,5 @@ LocalAI follows the Linux kernel project's [guidelines for AI coding assistants]
 - **Go style**: Prefer `any` over `interface{}`
 - **Comments**: Explain *why*, not *what*
 - **Docs**: Update `docs/content/` when adding features or changing config
-- **New API endpoints**: LocalAI advertises its capability surface in several independent places — swagger `@Tags`, `/api/instructions` registry, auth `RouteFeatureRegistry`, React UI `capabilities.js`, docs. Read [.agents/api-endpoints-and-auth.md](.agents/api-endpoints-and-auth.md) and follow its checklist — missing any surface means clients, admins, and the UI won't know the endpoint exists.
-- **Admin endpoints → MCP tool**: every admin endpoint that an admin would manage conversationally (install/list/edit/toggle/upgrade) MUST also be exposed as an MCP tool in `pkg/mcp/localaitools/`. The LocalAI Assistant chat modality and the standalone `local-ai mcp-server` consume that package; drift between REST and MCP is a real risk. Read [.agents/localai-assistant-mcp.md](.agents/localai-assistant-mcp.md) — the `TestToolHTTPRouteMappingComplete` test fails until you wire the new tool and update the route map.
 - **Build**: Inspect `Makefile` and `.github/workflows/` — ask the user before running long builds
 - **UI**: The active UI is the React app in `core/http/react-ui/`. The older Alpine.js/HTML UI in `core/http/static/` is pending deprecation — all new UI work goes in the React UI

-## AI Coding Assistants
-
-LocalAI follows the **same guidelines as the Linux kernel project** for AI-assisted contributions: <https://docs.kernel.org/process/coding-assistants.html>.
-
-The full policy for this repository lives in [`.agents/ai-coding-assistants.md`](.agents/ai-coding-assistants.md). Summary:
-
-- **AI agents MUST NOT add `Signed-off-by` tags.** Only humans can certify the Developer Certificate of Origin.
-- **AI agents MUST NOT add `Co-Authored-By` trailers** attributing themselves as co-authors.
-- **Attribute AI involvement with an `Assisted-by` trailer** in the commit message:
-
-  ```
-  Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]
-  ```
-
-  Example: `Assisted-by: Claude:claude-opus-4-7 golangci-lint`
-
-  Basic development tools (git, go, make, editors) should not be listed.
-- **The human submitter is responsible** for reviewing, testing, and fully understanding every line of AI-generated code — including verifying that any referenced APIs, flags, or file paths actually exist in the tree.
-- Contributions must remain compatible with LocalAI's **MIT License**.
-
 ## Testing
 
 All new features and bug fixes should include test coverage. The project uses [Ginkgo](https://onsi.github.io/ginkgo/) as its test framework.

-## End-to-end gRPC tests that exercise a built backend container image.
-##
-## The test suite in tests/e2e-backends is backend-agnostic. You drive it via env
-## vars (see tests/e2e-backends/backend_test.go for the full list) and the
-## capability-driven harness picks which gRPC RPCs to exercise:
-##
-##   BACKEND_IMAGE            Required. Docker image to test, e.g. local-ai-backend:llama-cpp.
-##   BACKEND_TEST_MODEL_URL   URL of a model file to download and load.
-##   BACKEND_TEST_MODEL_FILE  Path to an already-downloaded model (skips download).
-##   BACKEND_TEST_MODEL_NAME  HuggingFace repo id (e.g. Qwen/Qwen2.5-0.5B-Instruct).
-##                            Use this instead of MODEL_URL for backends that
-##                            resolve HF model ids natively (vllm, vllm-omni).
-##   BACKEND_TEST_CAPS        Comma-separated capabilities, default "health,load,predict,stream".
-##                            Adds "tools" to exercise ChatDelta tool call extraction.
-##   BACKEND_TEST_PROMPT      Override the prompt used in predict/stream specs.
-##   BACKEND_TEST_OPTIONS     Comma-separated Options[] entries forwarded to LoadModel,
-##                            e.g. "tool_parser:hermes,reasoning_parser:qwen3".

-#
-# This Dockerfile is the source of truth for the

-# `.github/workflows/base-images.yml` builds and pushes. The output of a
-# build is a fully-prepped builder layer containing:
-#
-#   - apt build deps (build-essential, ccache, git, make, pkg-config,
-#     libcurl4-openssl-dev, libssl-dev, curl, unzip, wget, ca-certificates)
-#   - cmake (apt or, when CMAKE_FROM_SOURCE=true, compiled from
-#     ${CMAKE_VERSION})
-#   - protoc v27.1 at /usr/local/bin/protoc
-#   - gRPC ${GRPC_VERSION} compiled and installed at /opt/grpc
-#   - Conditional CUDA toolkit (BUILD_TYPE=cublas|l4t, SKIP_DRIVERS=false)
-#     including the cuda-13 + arm64 cudss/nvpl special case
-#   - Conditional ROCm/HIP build deps (BUILD_TYPE=hipblas)
-#   - Conditional Vulkan SDK 1.4.335.0 (BUILD_TYPE=vulkan)

-# This is a SINGLE-stage Dockerfile by design: the final image IS the
-# builder base. The intermediate gRPC compile happens inside this same
-# stage so consumer Dockerfiles in PR 2 can simply
-# `FROM quay.io/go-skynet/ci-cache:base-grpc-<variant>` without needing a
-# COPY --from=grpc step. /opt/grpc is the canonical install prefix and
-# downstream builds will add it to CMAKE_PREFIX_PATH (or copy to
-# /usr/local) the same way Dockerfile.llama-cpp does today.
-#
-# Install logic lives in .docker/install-base-deps.sh, which is also
-# bind-mounted by the variant Dockerfiles' builder-fromsource stage.
-# This guarantees bit-equivalence between the prebuilt CI base and the
-# from-source local-dev path — both invoke the same script with the
-# same env inputs.

-#      fork-specific `turbo2` / `turbo3` / `turbo4` cache types.
-#   2. Replace `get_media_marker()` (added upstream in ggml-org/llama.cpp#21962,

-#      backend does not expose media_marker, so substituting the literal keeps
-#      behavior identical on the turboquant path.
-#   3. Revert the `common_params_speculative` field references to the
