+# Adding a New Backend
+
+When adding a new backend to LocalAI, you need to update several files to ensure the backend is properly built, tested, and registered. Here's a step-by-step guide based on the pattern used for adding backends like `moonshine`:
+
+## 1. Create Backend Directory Structure
+
+Create the backend directory under the appropriate location:
+- **Python backends**: `backend/python/<backend-name>/`
+- **Go backends**: `backend/go/<backend-name>/`
+- **C++ backends**: `backend/cpp/<backend-name>/`
+- **Rust backends**: `backend/rust/<backend-name>/`
+
+For Python backends, you'll typically need:
+- `backend.py` - Main gRPC server implementation
+- `Makefile` - Build configuration
+- `install.sh` - Installation script for dependencies
+- `protogen.sh` - Protocol buffer generation script
+- `requirements.txt` - Python dependencies
+- `run.sh` - Runtime script
+- `test.py` / `test.sh` - Test files
+
+For Rust backends, you'll typically need (see `backend/rust/kokoros/` as a reference):
+- `Cargo.toml` - Crate manifest; depend on the upstream project as a submodule under `sources/`
+- `build.rs` - Invokes `tonic_build` to generate gRPC stubs from `backend/backend.proto` (use the `BACKEND_PROTO_PATH` env var so the Makefile can inject the canonical copy)
+- `src/` - The gRPC server implementation (implement `Backend` via `tonic`)
+- `Makefile` - Copies `backend.proto` into the crate, runs `cargo build --release`, then `package.sh`
+- `package.sh` - Uses `ldd` to bundle the binary's dynamic deps and `ld.so` into `package/lib/`
+- `run.sh` - Sets `LD_LIBRARY_PATH`/`SSL_CERT_DIR` and execs the binary via the bundled `lib/ld.so`
+- `sources/<UpstreamProject>/` - Git submodule with the upstream Rust crate
+
+## 2. Add Build Configurations to `.github/backend-matrix.yml`
+
+The build matrix is data-only YAML at `.github/backend-matrix.yml` (not inside `backend.yml` itself). `backend.yml` (master push) and `backend_pr.yml` (PR) load it via `scripts/changed-backends.js`, which also handles per-file path filtering so only touched backends rebuild on PRs and master pushes alike. Add build matrix entries to `.github/backend-matrix.yml` for each platform/GPU type you want to support. Look at similar backends for reference — `chatterbox`/`faster-whisper` for Python, `piper`/`silero-vad` for Go, `kokoros` for Rust.
+
+**Without an entry here no image is ever built or pushed, and the gallery entry in `backend/index.yaml` will point at a tag that does not exist.** The `dockerfile:` field must point at `./backend/Dockerfile.<lang>` matching the language bucket from step 1 (e.g. `Dockerfile.python`, `Dockerfile.golang`, `Dockerfile.rust`). The `tag-suffix` must match the `uri:` in the corresponding `backend/index.yaml` image entry exactly.
+
+**`scripts/changed-backends.js` registration — REQUIRED for any new dockerfile suffix.** This is the single most common omission, because it has no effect on the PR that adds the backend (when no prior path filter could catch it anyway) — it only breaks the *next* PR that touches your backend's directory, which then gets zero CI jobs and looks broken for unrelated reasons. Edit `scripts/changed-backends.js:inferBackendPath` and add a branch BEFORE the more-generic suffixes:
+
+```js
+if (item.dockerfile.endsWith("<your-dockerfile-suffix>")) {
+    return `backend/cpp/<your-backend>/`;   // or backend/python|go|rust/...
+}
+```
+
+The `endsWith()` test is against the matrix entry's `dockerfile:` value (e.g. `./backend/Dockerfile.ds4` → `endsWith("ds4")`). Specificity order matters here just like it does for importers: more-specific suffixes go BEFORE more-generic ones (e.g. `ds4` before `llama-cpp` even though both end with letters, because some upstream might one day call itself `super-ds4-llama-cpp`). Verify locally before pushing:
+
+```bash
+# Confirm your dockerfile suffix is unique enough
+node -e "
+const yaml = require('js-yaml'); const fs = require('fs');
+const m = yaml.load(fs.readFileSync('.github/backend-matrix.yml','utf8'));
+for (const e of m.include.filter(e => e.backend === '<your-backend>')) {
+  console.log(e.dockerfile, '->', e.dockerfile.endsWith('<suffix>'));
+}"
+```
+
+A quick way to find the right insertion point: `grep -n 'item.dockerfile.endsWith' scripts/changed-backends.js`.
+
+**`bump_deps.yaml` registration — REQUIRED for any backend pinning an upstream commit.** If your backend's Makefile has a `*_VERSION?=<sha>` pin to a third-party repo, the daily auto-bump bot at `.github/workflows/bump_deps.yaml` won't notice it unless you register the backend in its matrix. The bot runs `.github/bump_deps.sh` which `grep`s for `^$VAR?=` in the Makefile you list — so the pin MUST live in the Makefile (not in a separate shell script). The bump for ds4 (#9761) had to walk this back because the original landed the pin in `prepare.sh`, which the bot can't see. Pattern (for `antirez/ds4`):
+
+```yaml
+# .github/workflows/bump_deps.yaml
+matrix:
+  include:
+    - repository: "antirez/ds4"
+      variable: "DS4_VERSION"
+      branch: "main"
+      file: "backend/cpp/ds4/Makefile"
+```
+
+And the corresponding Makefile shape (mirror `backend/cpp/llama-cpp/Makefile`):
+
+```makefile
+DS4_VERSION?=ae302c2fa18cc6d9aefc021d0f27ae03c9ad2fc0
+DS4_REPO?=https://github.com/antirez/ds4
+...
+ds4:
+	mkdir -p ds4
+	cd ds4 && git init -q && \
+	git remote add origin $(DS4_REPO) && \
+	git fetch --depth 1 origin $(DS4_VERSION) && \
+	git checkout FETCH_HEAD
+```
+
+If you have a `prepare.sh` doing the clone, delete it — the recipe belongs in the Makefile target so `make purge && make` works as a clean-and-rebuild and so the bump bot finds the pin.
+
+**Placement in file:**
+- CPU builds: Add after other CPU builds (e.g., after `cpu-chatterbox`)
+- CUDA 12 builds: Add after other CUDA 12 builds (e.g., after `gpu-nvidia-cuda-12-chatterbox`)
+- CUDA 13 builds: Add after other CUDA 13 builds (e.g., after `gpu-nvidia-cuda-13-chatterbox`)
+
+**Additional build types you may need:**
+- ROCm/HIP: Use `build-type: 'hipblas'` with `base-image: "rocm/dev-ubuntu-24.04:7.2.1"`
+- Intel/SYCL: Use `build-type: 'intel'` or `build-type: 'sycl_f16'`/`sycl_f32` with `base-image: "intel/oneapi-basekit:2025.3.2-0-devel-ubuntu24.04"`
+- L4T (ARM): Use `build-type: 'l4t'` with `platforms: 'linux/arm64'` and `runs-on: 'ubuntu-24.04-arm'`
+
+**Per-arch native builds (`linux/amd64` + `linux/arm64`):**
+
+Multi-arch backends are NOT a single matrix entry with `platforms: 'linux/amd64,linux/arm64'`. Instead, add **two** entries — one with `platforms: 'linux/amd64'` + `platform-tag: 'amd64'` + `runs-on: 'ubuntu-latest'`, one with `platforms: 'linux/arm64'` + `platform-tag: 'arm64'` + `runs-on: 'ubuntu-24.04-arm'` — both sharing the same `tag-suffix`. The script detects the shared `tag-suffix` and emits a `merge-matrix` entry, so `backend-merge-jobs` (in `backend.yml`/`backend_pr.yml`) automatically assembles the manifest list from per-arch digest artifacts. See `-cpu-faster-whisper` in `.github/backend-matrix.yml` for a reference shape.
+
+**llama-cpp / ik-llama-cpp / turboquant variants only — `builder-base-image`:**
+
+Entries whose `dockerfile` is `./backend/Dockerfile.{llama-cpp,ik-llama-cpp,turboquant}` must also set a `builder-base-image` field pointing at a prebuilt base from `quay.io/go-skynet/ci-cache:base-grpc-*` (CI builds these via `.github/workflows/base-images.yml`). 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.
+
+## 3. Add Backend Metadata to `backend/index.yaml`
+
+**Step 3a: Add Meta Definition**
+
+Add a YAML anchor definition in the `## metas` section (around line 2-300). Look for similar backends to use as a template such as `diffusers` or `chatterbox`
+
+**Step 3b: Add Image Entries**
+
+Add image entries at the end of the file, following the pattern of similar backends such as `diffusers` or `chatterbox`. Include both `latest` (production) and `master` (development) tags.
+
+**Note on integrity:** OCI backends installed from a gallery whose `verification:` block is set are verified against a keyless-cosign policy before extraction; tarball/HTTP backends use the optional `sha256:` field. New backends do not need any extra YAML — the gallery-level `verification:` block covers every entry. See [.agents/backend-signing.md](backend-signing.md) for the producer-side CI step.
+
+## 4. Update the Makefile
+
+The Makefile needs to be updated in several places to support building and testing the new backend:
+
+**Step 4a: Add to `.NOTPARALLEL`**
+
+Add `backends/<backend-name>` to the `.NOTPARALLEL` line (around line 2) to prevent parallel execution conflicts:
+
+```makefile
+.NOTPARALLEL: ... backends/<backend-name>
+```
+
+**Step 4b: Add to `prepare-test-extra`**
+
+Add the backend to the `prepare-test-extra` target to prepare it for testing. Use the path matching your language bucket (`backend/python/`, `backend/go/`, `backend/rust/`, …):
+
+```makefile
+prepare-test-extra: protogen-python
+	...
+	$(MAKE) -C backend/<lang>/<backend-name>
+```
+
+For Rust backends the target is usually the crate build target itself (e.g. `$(MAKE) -C backend/rust/<backend-name> <backend-name>-grpc`) so the binary is in place before `test` runs.
+
+**Step 4c: Add to `test-extra`**
+
+Add the backend to the `test-extra` target to run its tests — applies to Go and Rust backends too, not only Python:
+
+```makefile
+test-extra: prepare-test-extra
+	...
+	$(MAKE) -C backend/<lang>/<backend-name> test
+```
+
+Each backend's own `Makefile` should define a `test` target so this line works regardless of language. Integration tests that need large model downloads should be gated behind an env var (see `backend/rust/kokoros/`'s `KOKOROS_MODEL_PATH` pattern) so CI only runs unit tests.
+
+**Step 4d: Add Backend Definition**
+
+Add a backend definition variable in the backend definitions section (around line 428-457). The format depends on the backend type:
+
+**For Python backends with root context** (like `faster-whisper`, `coqui`):
+```makefile
+BACKEND_<BACKEND_NAME> = <backend-name>|python|.|false|true
+```
+
+**For Python backends with `./backend` context** (like `chatterbox`, `moonshine`):
+```makefile
+BACKEND_<BACKEND_NAME> = <backend-name>|python|./backend|false|true
+```
+
+**For Go backends**:
+```makefile
+BACKEND_<BACKEND_NAME> = <backend-name>|golang|.|false|true
+```
+
+**For Rust backends**:
+```makefile
+BACKEND_<BACKEND_NAME> = <backend-name>|rust|.|false|true
+```
+
+The language field (`python`/`golang`/`rust`/…) must match a `backend/Dockerfile.<lang>` file.
+
+**Step 4e: Generate Docker Build Target**
+
+Add an eval call to generate the docker-build target (around line 480-501):
+
+```makefile
+$(eval $(call generate-docker-build-target,$(BACKEND_<BACKEND_NAME>)))
+```
+
+**Step 4f: Add to `docker-build-backends`**
+
+Add `docker-build-<backend-name>` to the `docker-build-backends` target (around line 507):
+
+```makefile
+docker-build-backends: ... docker-build-<backend-name>
+```
+
+**Determining the Context:**
+
+- If the backend is in `backend/python/<backend-name>/` and uses `./backend` as context in the workflow file, use `./backend` context
+- If the backend is in `backend/python/<backend-name>/` but uses `.` as context in the workflow file, use `.` context
+- Check similar backends to determine the correct context
+
+## 5. Verification Checklist
+
+After adding a new backend, verify:
+
+- [ ] Backend directory structure is complete with all necessary files
+- [ ] Build configurations added to `.github/backend-matrix.yml` for all desired platforms (per-arch entries with `platform-tag` for multi-arch; `builder-base-image` for llama-cpp / ik-llama-cpp / turboquant)
+- [ ] Meta definition added to `backend/index.yaml` in the `## metas` section
+- [ ] Image entries added to `backend/index.yaml` for all build variants (latest + development)
+- [ ] Tag suffixes match between workflow file and index.yaml
+- [ ] Makefile updated with all 6 required changes (`.NOTPARALLEL`, `prepare-test-extra`, `test-extra`, backend definition, docker-build target eval, `docker-build-backends`)
+- [ ] No YAML syntax errors (check with linter)
+- [ ] No Makefile syntax errors (check with linter)
+- [ ] Follows the same pattern as similar backends (e.g., if it's a transcription backend, follow `faster-whisper` pattern)
+
+## 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.
+
+## 6. Example: Adding a Python Backend
+
+For reference, when `moonshine` was added:
+- **Files created**: `backend/python/moonshine/{backend.py, Makefile, install.sh, protogen.sh, requirements.txt, run.sh, test.py, test.sh}`
+- **Workflow entries**: 3 build configurations (CPU, CUDA 12, CUDA 13)
+- **Index entries**: 1 meta definition + 6 image entries (cpu, cuda12, cuda13 x latest/development)
+- **Makefile updates**:
+  - Added to `.NOTPARALLEL` line
+  - Added to `prepare-test-extra` and `test-extra` targets
+  - Added `BACKEND_MOONSHINE = moonshine|python|./backend|false|true`
+  - Added eval for docker-build target generation
+  - Added `docker-build-moonshine` to `docker-build-backends`

+# 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

+The human submitter must:
+
+- Understand every line that lands in the PR
+- Verify that generated code compiles, passes tests, and follows the
+  project style
+- Confirm that any referenced APIs, flags, or file paths actually exist
+  in the current tree (AI models may hallucinate identifiers)
+- Not submit AI output verbatim without review
+
+Reviewers may ask for clarification on any change regardless of how it
+was produced. "An AI wrote it" is not an acceptable answer to a design
+question.

+# API Endpoints and Authentication
+
+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:
+
+1. **Global auth middleware** (`core/http/auth/middleware.go` → `auth.Middleware`) — applied to every request in `core/http/app.go`. Handles session cookies, Bearer tokens, API keys, and legacy API keys. Populates `auth_user` and `auth_role` in the Echo context.
+2. **Feature middleware** (`auth.RequireFeature`) — per-feature access control applied to route groups or individual routes. Checks if the authenticated user has the specific feature enabled.
+3. **Admin middleware** (`auth.RequireAdmin`) — restricts endpoints to admin users only.
+
+When auth is disabled (no auth DB, no legacy API keys), all middleware becomes pass-through (`auth.NoopMiddleware`).
+
+## Adding a new API endpoint
+
+### Step 1: Create the handler
+
+Write the endpoint handler in the appropriate package under `core/http/endpoints/`. Follow existing patterns:
+
+```go
+// core/http/endpoints/localai/my_feature.go
+func MyFeatureEndpoint(app *application.Application) echo.HandlerFunc {
+    return func(c echo.Context) error {
+        // Use auth.GetUser(c) to get the authenticated user (may be nil if auth is disabled)
+        user := auth.GetUser(c)
+
+        // Your logic here
+        return c.JSON(http.StatusOK, result)
+    }
+}
+```
+
+### Step 2: Register routes
+
+Add routes in the appropriate file under `core/http/routes/`. The file you use depends on the endpoint category:
+
+| File | Category |
+|------|----------|
+| `routes/openai.go` | OpenAI-compatible API endpoints (`/v1/...`) |
+| `routes/localai.go` | LocalAI-specific endpoints (`/api/...`, `/models/...`, `/backends/...`) |
+| `routes/agents.go` | Agent pool endpoints (`/api/agents/...`) |
+| `routes/auth.go` | Auth endpoints (`/api/auth/...`) |
+| `routes/ui_api.go` | UI backend API endpoints |
+
+### Step 3: Apply the right middleware
+
+Choose the appropriate protection level:
+
+#### No auth required (public)
+Exempt paths bypass auth entirely. Add to `isExemptPath()` in `middleware.go` or use the `/api/auth/` prefix (always exempt). Use sparingly — most endpoints should require auth.
+
+#### Standard auth (any authenticated user)
+The global middleware already handles this. API paths (`/api/`, `/v1/`, etc.) automatically require authentication when auth is enabled. You don't need to add any extra middleware.
+
+```go
+router.GET("/v1/my-endpoint", myHandler)  // auth enforced by global middleware
+```
+
+#### Admin only
+Pass `adminMiddleware` to the route. This is set up in `app.go` and passed to `Register*Routes` functions:
+
+```go
+// In the Register function signature, accept the middleware:
+func RegisterMyRoutes(router *echo.Echo, app *application.Application, adminMiddleware echo.MiddlewareFunc) {
+    router.POST("/models/apply", myHandler, adminMiddleware)
+}
+```
+
+#### Feature-gated
+For endpoints that should be toggleable per-user, use feature middleware. There are two approaches:
+
+**Approach A: Route-level middleware** (preferred for groups of related endpoints)
+
+```go
+// In app.go, create the feature middleware:
+myFeatureMw := auth.RequireFeature(application.AuthDB(), auth.FeatureMyFeature)
+
+// Pass it to the route registration function:
+routes.RegisterMyRoutes(e, app, myFeatureMw)
+
+// In the routes file, apply to a group:
+g := e.Group("/api/my-feature", myFeatureMw)
+g.GET("", listHandler)
+g.POST("", createHandler)
+```
+
+**Approach B: RouteFeatureRegistry** (preferred for individual OpenAI-compatible endpoints)
+
+Add an entry to `RouteFeatureRegistry` in `core/http/auth/features.go`. The `RequireRouteFeature` global middleware will automatically enforce it:
+
+```go
+var RouteFeatureRegistry = []RouteFeature{
+    // ... existing entries ...
+    {"POST", "/v1/my-endpoint", FeatureMyFeature},
+}
+```
+
+## Adding a new feature
+
+When you need a new toggleable feature (not just a new endpoint under an existing feature):
+
+### 1. Define the feature constant
+
+Add to `core/http/auth/permissions.go`:
+
+```go
+const (
+    // Add to the appropriate group:
+    // Agent features (default OFF for new users)
+    FeatureMyFeature = "my_feature"
+
+    // OR API features (default ON for new users)
+    FeatureMyFeature = "my_feature"
+)
+```
+
+Then add it to the appropriate slice:
+
+```go
+// Default OFF — user must be explicitly granted access:
+var AgentFeatures = []string{..., FeatureMyFeature}
+
+// Default ON — user has access unless explicitly revoked:
+var APIFeatures = []string{..., FeatureMyFeature}
+```
+
+### 2. Add feature metadata
+
+In `core/http/auth/features.go`, add to the appropriate `FeatureMetas` function so the admin UI can display it:
+
+```go
+func AgentFeatureMetas() []FeatureMeta {
+    return []FeatureMeta{
+        // ... existing ...
+        {FeatureMyFeature, "My Feature", false},  // false = default OFF
+    }
+}
+```
+
+### 3. Wire up the middleware
+
+In `core/http/app.go`:
+
+```go
+myFeatureMw := auth.RequireFeature(application.AuthDB(), auth.FeatureMyFeature)
+```
+
+Then pass it to the route registration function.
+
+### 4. Register route-feature mappings (if applicable)
+
+If your feature gates standard API endpoints (like `/v1/...`), add entries to `RouteFeatureRegistry` in `features.go` instead of using per-route middleware.
+
+## Accessing the authenticated user in handlers
+
+```go
+import "github.com/mudler/LocalAI/core/http/auth"
+
+func MyHandler(c echo.Context) error {
+    // Get the user (nil when auth is disabled or unauthenticated)
+    user := auth.GetUser(c)
+    if user == nil {
+        // Handle unauthenticated — or let middleware handle it
+    }
+
+    // Check role
+    if user.Role == auth.RoleAdmin {
+        // admin-specific logic
+    }
+
+    // Check feature access programmatically (when you need conditional behavior, not full blocking)
+    if auth.HasFeatureAccess(db, user, auth.FeatureMyFeature) {
+        // feature-specific logic
+    }
+
+    // Check model access
+    if !auth.IsModelAllowed(db, user, modelName) {
+        return c.JSON(http.StatusForbidden, ...)
+    }
+}
+```
+
+## Middleware composition patterns
+
+Middleware can be composed at different levels. Here are the patterns used in the codebase:
+
+### Group-level middleware (agents pattern)
+```go
+// All routes in the group share the middleware
+g := e.Group("/api/agents", poolReadyMw, agentsMw)
+g.GET("", listHandler)
+g.POST("", createHandler)
+```
+
+### Per-route middleware (localai pattern)
+```go
+// Individual routes get middleware as extra arguments
+router.POST("/models/apply", applyHandler, adminMiddleware)
+router.GET("/metrics", metricsHandler, adminMiddleware)
+```
+
+### Middleware slice (openai pattern)
+```go
+// Build a middleware chain for a handler
+chatMiddleware := []echo.MiddlewareFunc{
+    usageMiddleware,
+    traceMiddleware,
+    modelFilterMiddleware,
+}
+app.POST("/v1/chat/completions", chatHandler, chatMiddleware...)
+```
+
+## Error response format
+
+Always use `schema.ErrorResponse` for auth/permission errors to stay consistent with the OpenAI-compatible API:
+
+```go
+return c.JSON(http.StatusForbidden, schema.ErrorResponse{
+    Error: &schema.APIError{
+        Message: "feature not enabled for your account",
+        Code:    http.StatusForbidden,
+        Type:    "authorization_error",
+    },
+})
+```
+
+Use these HTTP status codes:
+- `401 Unauthorized` — no valid credentials provided
+- `403 Forbidden` — authenticated but lacking permission
+- `429 Too Many Requests` — rate limited (auth endpoints)
+
+## Usage tracking
+
+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), you need to update **all** of:
+
+- `Usecase<Name>` string constant in `core/config/backend_capabilities.go`
+- `UsecaseInfoMap` entry mapping the string to its flag + gRPC method
+- `FLAG_<NAME>` bitmask in `core/config/model_config.go`
+- `GetAllModelConfigUsecases()` map entry (otherwise the YAML loader silently ignores the string)
+- `ModalityGroups` membership if the flag should affect `IsMultimodal()` (e.g. realtime_audio is in both speech-input and audio-output groups so a lone flag still reads as multimodal)
+- `GuessUsecases()` branch listing the backends that own this capability
+- `usecaseFilters` in `core/http/routes/ui_api.go` (drives the gallery filter dropdown)
+- `Models.jsx` `FILTERS` array + matching `filters.<camelCase>` i18n key in `core/http/react-ui/public/locales/en/models.json`
+- `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`.
+
+## Path protection rules
+
+The global auth middleware classifies paths as API paths or non-API paths:
+
+- **API paths** (always require auth when auth is enabled): `/api/`, `/v1/`, `/models/`, `/backends/`, `/backend/`, `/tts`, `/vad`, `/video`, `/stores/`, `/system`, `/ws/`, `/metrics`
+- **Exempt paths** (never require auth): `/api/auth/` prefix, anything in `appConfig.PathWithoutAuth`
+- **Non-API paths** (UI, static assets): pass through without auth — the React UI handles login redirects client-side
+
+If you add endpoints under a new top-level path prefix, add it to `isAPIPath()` in `middleware.go` to ensure it requires authentication.
+
+## Checklist
+
+When adding a new endpoint:
+
+**Routing & auth**
+- [ ] Handler in `core/http/endpoints/`
+- [ ] Route registered in appropriate `core/http/routes/` file
+- [ ] Auth level chosen: public / standard / admin / feature-gated
+- [ ] Entry added to `RouteFeatureRegistry` in `core/http/auth/features.go` (one row per route/method — all /v1/* routes gate through this, not per-route middleware)
+- [ ] If new feature: constant in `permissions.go`, added to the right slice (`APIFeatures` default-ON / `AgentFeatures` default-OFF), metadata in `features.go` `*FeatureMetas()`
+- [ ] If feature uses group middleware: wired in `core/http/app.go` and passed to the route registration function
+- [ ] If new path prefix: added to `isAPIPath()` in `middleware.go`
+- [ ] If token-counting: `usageMiddleware` added to middleware chain
+
+**Advertising surfaces (easy to miss — see the [Advertising surfaces](#advertising-surfaces--where-to-register-a-new-capability) section)**
+- [ ] Swagger block on the handler: `@Summary`, `@Tags`, `@Param`, `@Success`, `@Router`
+- [ ] If new capability area (new swagger tag): entry in `instructionDefs` in `core/http/endpoints/localai/api_instructions.go` + test count bumped in `api_instructions_test.go`
+- [ ] If new `FLAG_*` usecase flag: matching `CAP_*` symbol exported from `core/http/react-ui/src/utils/capabilities.js`
+- [ ] `docs/content/features/<feature>.md` created; cross-links from related feature pages; entry in `docs/content/whats-new.md`
+
+**Quality**
+- [ ] Error responses use `schema.ErrorResponse` format (or `echo.NewHTTPError` with a mapped gRPC status — see the `mapBackendError` helper in `core/http/endpoints/localai/images.go`)
+- [ ] Tests cover both authenticated and unauthenticated access
+- [ ] Swagger regenerated (`make swagger`) if you changed any `@Router`/`@Tags`/`@Param` annotation
+
+## 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.

+# Backend image signing & verification
+
+LocalAI verifies backend OCI images against a per-gallery keyless-cosign
+policy. This page documents the trust model, the producer side
+(`.github/workflows/backend_merge.yml` in this repo), and the consumer
+side (`pkg/oci/cosignverify` plus the gallery YAML).
+
+## Trust model
+
+- **Producer:** `.github/workflows/backend_merge.yml` signs each pushed
+  manifest list with `cosign sign --recursive` in keyless mode after
+  `docker buildx imagetools create`. The signing cert is issued by
+  Fulcio bound to the workflow's OIDC identity. There is no long-lived
+  signing key. `--recursive` signs both the manifest list and every
+  per-arch entry — needed because our consumer resolves a tag to a
+  per-arch manifest before checking signatures.
+- **Storage:** Signatures are written as OCI 1.1 referrers
+  (`--registry-referrers-mode=oci-1-1`) in the new Sigstore bundle format
+  (`--new-bundle-format`). No `:sha256-<hex>.sig` tag clutter.
+- **Consumer:** `pkg/oci/cosignverify` discovers the bundle via the
+  referrers API, hands it to `sigstore-go`, and verifies it against the
+  policy declared in the gallery YAML (`Gallery.Verification`).
+- **Revocation:** Keyless cosign certs are ephemeral (10-minute Fulcio
+  validity), so revocation is policy-side, not CA-side. The gallery's
+  `verification.not_before` (RFC3339) is the kill-switch — advance it to
+  invalidate every signature produced before a known compromise window.
+
+## Producer setup
+
+`backend_merge.yml` is the workflow that joins per-arch digests into the
+multi-arch manifest list users actually pull, so it's also the right place
+to sign. The job needs:
+
+- `permissions: { id-token: write, contents: read }` at the job level so
+  the runner can exchange its GitHub OIDC token for a Fulcio cert.
+- `sigstore/cosign-installer@v3` step (cosign ≥ 2.2 for
+  `--new-bundle-format`).
+- After each `docker buildx imagetools create`, resolve the resulting
+  list digest with `docker buildx imagetools inspect <tag> --format
+  '{{.Manifest.Digest}}'` and sign:
+
+```sh
+cosign sign --yes --recursive \
+  --new-bundle-format \
+  --registry-referrers-mode=oci-1-1 \
+  "${REGISTRY_REPO}@${DIGEST}"
+```
+
+Sign by digest, never by tag — signing by tag binds the signature to
+whatever the tag points at *now*, and a subsequent tag push orphans it.
+
+`backend_build_darwin.yml` builds and pushes single-arch darwin images
+that bypass the manifest-list merge. If/when those entries get a gallery
+`verification:` policy, the equivalent cosign step has to land there
+too.
+
+## Consumer setup (in `mudler/LocalAI` gallery YAML)
+
+Once CI is signing, add a `verification:` block to the backend gallery
+entry (`backend/index.yaml`):
+
+```yaml
+- name: localai
+  url: github:mudler/LocalAI/backend/index.yaml@master
+  verification:
+    issuer: "https://token.actions.githubusercontent.com"
+    identity_regex: "^https://github\\.com/mudler/LocalAI/\\.github/workflows/backend_merge\\.yml@refs/heads/master$"
+    # Optional revocation cutoff; advance during incident response.
+    # not_before: "2026-06-01T00:00:00Z"
+```
+
+Identity matching pins the OIDC subject Fulcio issued the signing cert
+to. Without this, any image signed by *anyone* with a Fulcio cert would
+pass — the regex is what makes a signature mean "produced by our CI".
+
+## Strict mode
+
+Default behaviour: OCI backends without a `verification:` block install
+with a warning (logs include `installing OCI backend without signature
+verification`). Tarball/HTTP backends without a `sha256` field log a
+similar warning.
+
+For production, set `LOCALAI_REQUIRE_BACKEND_INTEGRITY=1` (or pass
+`--require-backend-integrity` to `local-ai run` / `local-ai backends
+install` / `local-ai models install`). The warning becomes a hard error
+and unverifiable backends refuse to install.
+
+## Revocation playbook
+
+If `backend_merge.yml` (or any workflow with `id-token: write`) is
+compromised and we've shipped malicious signed images:
+
+1. **Identify the compromise window.** Find the earliest IntegratedTime
+   from the bad signatures (Rekor search by `subject` filter).
+2. **Set `verification.not_before`** in `backend/index.yaml` to a
+   timestamp just *after* that window's start.
+3. **Push the YAML.** Deployed LocalAI instances pick it up on next
+   gallery refresh (1-hour cache in `core/gallery/gallery.go`).
+4. **Fix the underlying compromise** in the workflow and re-sign images
+   with the new build, which will have IntegratedTime > `not_before`.
+5. **Optional:** for absolute decisiveness, also rotate to a new
+   workflow path (`backend_merge_v2.yml`) and update `identity_regex`.
+
+## Where the code lives
+
+- `pkg/oci/cosignverify/` — verifier, policy, OCI referrer fetch, NotBefore enforcement.
+- `pkg/downloader/uri.go` — `WithImageVerifier` option threaded through `DownloadFileWithContext`.
+- `core/gallery/backends.go` — `backendDownloadOptions` builds the verifier from the gallery's policy.
+- `core/config/gallery.go` — `Gallery.Verification` YAML schema.
+- `core/cli/run.go`, `core/cli/backends.go`, `core/cli/models.go` — `--require-backend-integrity` flag propagation.
+- `.github/workflows/backend_merge.yml` — producer-side `cosign sign --recursive` after each multi-arch manifest list push.
+
+## Out of scope (follow-ups)
+
+- **Signing the gallery YAML itself.** The index is fetched over HTTPS
+  from GitHub; we trust the host. A cosign blob signature on the YAML
+  would close that gap but adds key-management overhead. Revisit this
+  page if/when added.
+- **Tarball/HTTP backend signing.** Cosign can sign arbitrary blobs, but
+  for now non-OCI backends keep using the `sha256:` field in YAML.

+# Build and Testing
+
+Building and testing the project depends on the components involved and the platform where development is taking place. Due to the amount of context required it's usually best not to try building or testing the project unless the user requests it. If you must build the project then inspect the Makefile in the project root and the Makefiles of any backends that are effected by changes you are making. In addition the workflows in .github/workflows can be used as a reference when it is unclear how to build or test a component. The primary Makefile contains targets for building inside or outside Docker, if the user has not previously specified a preference then ask which they would like to use.
+
+## Building a specified backend
+
+Let's say the user wants to build a particular backend for a given platform. For example let's say they want to build coqui for ROCM/hipblas
+
+- The Makefile has targets like `docker-build-coqui` created with `generate-docker-build-target` at the time of writing. Recently added backends may require a new target.
+- At a minimum we need to set the BUILD_TYPE, BASE_IMAGE build-args
+  - Use `.github/backend-matrix.yml` as a reference — it's the data-only YAML that lists every backend variant's `build-type`, `base-image`, `platforms`, etc. (`backend.yml` and `backend_pr.yml` consume it via `scripts/changed-backends.js`).
+  - l4t and cublas also require the CUDA major and minor version.
+  - For llama-cpp / ik-llama-cpp / turboquant the matrix also sets `builder-base-image` pointing at a prebuilt `quay.io/go-skynet/ci-cache:base-grpc-*` tag. Local `make backends/<name>` defaults to `BUILDER_TARGET=builder-fromsource` and doesn't need it — the Dockerfile's from-source stage installs everything itself.
+- You can pretty print a command like `DOCKER_MAKEFLAGS=-j$(nproc --ignore=1) BUILD_TYPE=hipblas BASE_IMAGE=rocm/dev-ubuntu-24.04:7.2.1 make docker-build-coqui`
+- Unless the user specifies that they want you to run the command, then just print it because not all agent frontends handle long running jobs well and the output may overflow your context
+- The user may say they want to build AMD or ROCM instead of hipblas, or Intel instead of SYCL or NVIDIA insted of l4t or cublas. Ask for confirmation if there is ambiguity.
+- Sometimes the user may need extra parameters to be added to `docker build` (e.g. `--platform` for cross-platform builds or `--progress` to view the full logs), in which case you can generate the `docker build` command directly.

+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.
+2. **Keep `(tag-suffix, platform-tag)` unique per matrix entry** — together they're the cache namespace. Two matrix entries sharing a key would clobber each other's cache.
+3. **Keep `cache-to` gated on `github.event_name != 'pull_request'`** — PRs must not write.
+4. **Keep `ignore-error=true` on `cache-to`** — quay registry hiccups must not fail builds.
+5. **Keep `provenance: false` on push-by-digest steps** — multi-registry digest divergence is the Bug We Already Fixed; reintroducing provenance attestation re-breaks the merge.
+6. **`install-base-deps.sh` is the single source of truth for base contents.** Both `Dockerfile.base-grpc-builder` (CI) and the variant Dockerfiles' `builder-fromsource` (local) bind-mount and execute it. If you add a package to one path, add it to the script — don't fork the logic into a Dockerfile RUN.
+7. **After adding a `base-images.yml` matrix variant, run the workflow on your branch before merging consumer changes** that depend on the new tag — otherwise the consumer's CI fails "image not found."

+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`).
+
+## Documentation

+- **Configuration**: If you modify configuration options, update the relevant sections in `docs/content/`.
+- **Examples**: providing concrete examples (like YAML configuration blocks) is highly encouraged to help users get started quickly.
+- **Shortcodes**: Use `{{% notice note %}}`, `{{% notice tip %}}`, or `{{% notice warning %}}` for callout boxes. Do **not** use `{{% alert %}}` — that shortcode does not exist in this project's Hugo theme and will break the docs build.

+# Debugging and Rebuilding Backends
+
+When a backend fails at runtime (e.g. a gRPC method error, a Python import error, or a dependency conflict), use this guide to diagnose, fix, and rebuild.
+
+## Architecture Overview
+
+- **Source directory**: `backend/python/<name>/` (or `backend/go/<name>/`, `backend/cpp/<name>/`)
+- **Installed directory**: `backends/<name>/` — this is what LocalAI actually runs. It is populated by `make backends/<name>` which builds a Docker image, exports it, and installs it via `local-ai backends install`.
+- **Virtual environment**: `backends/<name>/venv/` — the installed Python venv (for Python backends). The Python binary is at `backends/<name>/venv/bin/python`.
+
+Editing files in `backend/python/<name>/` does **not** affect the running backend until you rebuild with `make backends/<name>`.
+
+## Diagnosing Failures
+
+### 1. Check the logs
+
+Backend gRPC processes log to LocalAI's stdout/stderr. Look for lines tagged with the backend's model ID:
+
+```
+GRPC stderr id="trl-finetune-127.0.0.1:37335" line="..."
+```
+
+Common error patterns:
+- **"Method not implemented"** — the backend is missing a gRPC method that the Go side calls. The model loader (`pkg/model/initializers.go`) always calls `LoadModel` after `Health`; fine-tuning backends must implement it even as a no-op stub.
+- **Python import errors / `AttributeError`** — usually a dependency version mismatch (e.g. `pyarrow` removing `PyExtensionType`).
+- **"failed to load backend"** — the gRPC process crashed or never started. Check stderr lines for the traceback.
+
+### 2. Test the Python environment directly
+
+You can run the installed venv's Python to check imports without starting the full server:
+
+```bash
+backends/<name>/venv/bin/python -c "import datasets; print(datasets.__version__)"
+```
+
+If `pip` is missing from the venv, bootstrap it:
+
+```bash
+backends/<name>/venv/bin/python -m ensurepip
+```
+
+Then use `backends/<name>/venv/bin/python -m pip install ...` to test fixes in the installed venv before committing them to the source requirements.
+
+### 3. Check upstream dependency constraints
+
+When you hit a dependency conflict, check what the main library expects. For example, TRL's upstream `requirements.txt`:
+
+```
+https://github.com/huggingface/trl/blob/main/requirements.txt
+```
+
+Pin minimum versions in the backend's requirements files to match upstream.
+
+## Common Fixes
+
+### Missing gRPC methods
+
+If the Go side calls a method the backend doesn't implement (e.g. `LoadModel`), add a no-op stub in `backend.py`:
+
+```python
+def LoadModel(self, request, context):
+    """No-op — actual loading happens elsewhere."""
+    return backend_pb2.Result(success=True, message="OK")
+```
+
+The gRPC contract requires `LoadModel` to succeed for the model loader to return a usable client, even if the backend doesn't need upfront model loading.
+
+### Dependency version conflicts
+
+Python backends often break when a transitive dependency releases a breaking change (e.g. `pyarrow` removing `PyExtensionType`). Steps:
+
+1. Identify the broken import in the logs
+2. Test in the installed venv: `backends/<name>/venv/bin/python -c "import <module>"`
+3. Check upstream requirements for version constraints
+4. Update **all** requirements files in `backend/python/<name>/`:
+   - `requirements.txt` — base deps (grpcio, protobuf)
+   - `requirements-cpu.txt` — CPU-specific (includes PyTorch CPU index)
+   - `requirements-cublas12.txt` — CUDA 12
+   - `requirements-cublas13.txt` — CUDA 13
+5. Rebuild: `make backends/<name>`
+
+### PyTorch index conflicts (uv resolver)
+
+The Docker build uses `uv` for pip installs. When `--extra-index-url` points to the PyTorch wheel index, `uv` may refuse to fetch packages like `requests` from PyPI if it finds a different version on the PyTorch index first. Fix this by adding `--index-strategy=unsafe-first-match` to `install.sh`:
+
+```bash
+EXTRA_PIP_INSTALL_FLAGS+=" --upgrade --index-strategy=unsafe-first-match"
+installRequirements
+```
+
+Most Python backends already do this — check `backend/python/transformers/install.sh` or similar for reference.
+
+## Rebuilding
+
+### Rebuild a single backend
+
+```bash
+make backends/<name>
+```
+
+This runs the Docker build (`Dockerfile.python`), exports the image to `backend-images/<name>.tar`, and installs it into `backends/<name>/`. It also rebuilds the `local-ai` Go binary (without extra tags).
+
+**Important**: If you were previously running with `GO_TAGS=auth`, the `make backends/<name>` step will overwrite your binary without that tag. Rebuild the Go binary afterward:
+
+```bash
+GO_TAGS=auth make build
+```
+
+### Rebuild and restart
+
+After rebuilding a backend, you must restart LocalAI for it to pick up the new backend files. The backend gRPC process is spawned on demand when the model is first loaded.
+
+```bash
+# Kill existing process
+kill <pid>
+
+# Restart
+./local-ai run --debug [your flags]
+```
+
+### Quick iteration (skip Docker rebuild)
+
+For fast iteration on a Python backend's `backend.py` without a full Docker rebuild, you can edit the installed copy directly:
+
+```bash
+# Edit the installed copy
+vim backends/<name>/backend.py
+
+# Restart LocalAI to respawn the gRPC process
+```
+
+This is useful for testing but **does not persist** — the next `make backends/<name>` will overwrite it. Always commit fixes to the source in `backend/python/<name>/`.
+
+## Verification
+
+After fixing and rebuilding:
+
+1. Start LocalAI and confirm the backend registers: look for `Registering backend name="<name>"` in the logs
+2. Trigger the operation that failed (e.g. start a fine-tuning job)
+3. Watch the GRPC stderr/stdout lines for the backend's model ID
+4. Confirm no errors in the traceback

+# Working on the ds4 Backend
+
+`antirez/ds4` is a single-model inference engine for DeepSeek V4 Flash.
+LocalAI wraps the engine's C API (`ds4/ds4.h`) with a fresh C++ gRPC server at
+`backend/cpp/ds4/` - NOT a fork of llama-cpp's grpc-server.cpp.
+
+## Pin
+
+`backend/cpp/ds4/Makefile` pins `DS4_VERSION?=<sha>` at the top. The `ds4`
+target in the Makefile clones `antirez/ds4` at that commit (mirroring the
+llama-cpp / ik-llama-cpp / turboquant pattern). The bump-deps bot
+(`.github/workflows/bump_deps.yaml`) finds this pin via grep and opens a
+daily PR to update it. To bump manually: edit the `DS4_VERSION?=` line,
+then `make purge && make` (or rely on CI's clean build).
+
+## Wire shape
+
+| RPC | Implementation |
+|---|---|
+| Health, Free, Status | Trivial; no engine dependency for Health |
+| LoadModel | `ds4_engine_open` + `ds4_session_create`; backend is compile-time (DS4_NO_GPU → CPU, __APPLE__ → Metal, otherwise CUDA) |
+| TokenizeString | `ds4_tokenize_text` |
+| Predict | `ds4_engine_generate_argmax` + `DsmlParser` → one ChatDelta with content / reasoning_content / tool_calls[] |
+| PredictStream | Same, per-token ChatDelta writes |
+
+## DSML
+
+ds4 emits tool calls as literal text markers (`<｜DSML｜tool_calls>` etc.) -
+NOT special tokens. `dsml_parser.{h,cpp}` is our streaming state machine that
+classifies token bytes into CONTENT / REASONING / TOOL_START / TOOL_ARGS / TOOL_END
+events. `dsml_renderer.{h,cpp}` does the prompt direction: turns
+OpenAI tool_calls + role=tool messages back into DSML for the next turn.
+
+## Thinking modes
+
+`PredictOptions.Metadata["enable_thinking"]` gates thinking on/off (default ON).
+`["reasoning_effort"] == "max" | "xhigh"` selects `DS4_THINK_MAX`; anything else
+maps to `DS4_THINK_HIGH`. We pass the chosen mode to `ds4_chat_append_assistant_prefix`.
+
+## Disk KV cache
+
+`kv_cache.{h,cpp}` implements an SHA1-keyed file cache using ds4's public
+`ds4_session_save_payload` / `ds4_session_load_payload` API. Enable per request
+via `ModelOptions.Options[] = "kv_cache_dir:/some/path"`. Format is **our own** -
+NOT bit-compatible with ds4-server's KVC files (interop is a follow-up plan).
+
+## Build matrix
+
+| Build | Where | Notes |
+|---|---|---|
+| `cpu-ds4` (amd64 + arm64) | Linux GHA | ds4 considers CPU debug-only; useful only for wiring tests |
+| `cuda13-ds4` (amd64 + arm64) | Linux GHA + DGX Spark validation | Primary production path on Linux |
+| `ds4-darwin` (arm64) | macOS GHA runners | Metal; uses `scripts/build/ds4-darwin.sh` like llama-cpp-darwin |
+
+cuda12 is intentionally omitted. ROCm / Vulkan / SYCL are not applicable.
+
+## Hardware-gated validation

+BACKEND_TEST_TOOL_PROMPT="What's the weather in Paris?" \
+go test -count=1 -timeout=30m -v ./tests/e2e-backends/...
+```
+
+CI does not load the model; the suite is opt-in via env vars.
+
+## Importer
+
+`core/gallery/importers/ds4.go` (`DS4Importer`) auto-detects ds4 weights by
+matching the `antirez/deepseek-v4-gguf` repo URI or the
+`DeepSeek-V4-Flash-*.gguf` filename pattern. **Registered BEFORE
+`LlamaCPPImporter`** in `defaultImporters` - both match `.gguf` but ds4 is more
+specific, and first-match-wins. The importer emits `backend: ds4`, uses
+`ds4flash.gguf` as the local filename (matches ds4's own CLI default), and
+disables the Go-side automatic tool-parsing fallback (the C++ backend emits
+ChatDelta.tool_calls natively via `DsmlParser`).
+
+ds4 is also listed in `core/http/endpoints/localai/backend.go`'s pref-only
+slice so the `/import-model` UI surfaces it as a manual choice for users who
+want to force the backend on a non-canonical URI.

+# llama.cpp Backend
+
+The llama.cpp backend (`backend/cpp/llama-cpp/grpc-server.cpp`) is a gRPC adaptation of the upstream HTTP server (`llama.cpp/tools/server/server.cpp`). It uses the same underlying server infrastructure from `llama.cpp/tools/server/server-context.cpp`.
+
+## Building and Testing
+
+- Test llama.cpp backend compilation: `make backends/llama-cpp`
+- The backend is built as part of the main build process
+- Check `backend/cpp/llama-cpp/Makefile` for build configuration
+
+## Architecture
+
+- **grpc-server.cpp**: gRPC server implementation, adapts HTTP server patterns to gRPC
+- Uses shared server infrastructure: `server-context.cpp`, `server-task.cpp`, `server-queue.cpp`, `server-common.cpp`
+- The gRPC server mirrors the HTTP server's functionality but uses gRPC instead of HTTP
+
+## Common Issues When Updating llama.cpp
+
+When fixing compilation errors after upstream changes:
+1. Check how `server.cpp` (HTTP server) handles the same change
+2. Look for new public APIs or getter methods
+3. Store copies of needed data instead of accessing private members
+4. Update function calls to match new signatures
+5. Test with `make backends/llama-cpp`
+
+## Key Differences from HTTP Server
+
+- gRPC uses `BackendServiceImpl` class with gRPC service methods
+- HTTP server uses `server_routes` with HTTP handlers
+- Both use the same `server_context` and task queue infrastructure
+- gRPC methods: `LoadModel`, `Predict`, `PredictStream`, `Embedding`, `Rerank`, `TokenizeString`, `GetMetrics`, `Health`
+
+## Tool Call Parsing Maintenance
+
+When working on JSON/XML tool call parsing functionality, always check llama.cpp for reference implementation and updates:
+
+### Checking for XML Parsing Changes
+
+1. **Review XML Format Definitions**: Check `llama.cpp/common/chat-parser-xml-toolcall.h` for `xml_tool_call_format` struct changes
+2. **Review Parsing Logic**: Check `llama.cpp/common/chat-parser-xml-toolcall.cpp` for parsing algorithm updates
+3. **Review Format Presets**: Check `llama.cpp/common/chat-parser.cpp` for new XML format presets (search for `xml_tool_call_format form`)
+4. **Review Model Lists**: Check `llama.cpp/common/chat.h` for `COMMON_CHAT_FORMAT_*` enum values that use XML parsing:
+   - `COMMON_CHAT_FORMAT_GLM_4_5`
+   - `COMMON_CHAT_FORMAT_MINIMAX_M2`
+   - `COMMON_CHAT_FORMAT_KIMI_K2`
+   - `COMMON_CHAT_FORMAT_QWEN3_CODER_XML`
+   - `COMMON_CHAT_FORMAT_APRIEL_1_5`
+   - `COMMON_CHAT_FORMAT_XIAOMI_MIMO`
+   - Any new formats added
+
+### Model Configuration Options
+
+Always check `llama.cpp` for new model configuration options that should be supported in LocalAI:
+
+1. **Check Server Context**: Review `llama.cpp/tools/server/server-context.cpp` for new parameters
+2. **Check Chat Params**: Review `llama.cpp/common/chat.h` for `common_chat_params` struct changes
+3. **Check Server Options**: Review `llama.cpp/tools/server/server.cpp` for command-line argument changes
+4. **Examples of options to check**:
+   - `ctx_shift` - Context shifting support
+   - `parallel_tool_calls` - Parallel tool calling
+   - `reasoning_format` - Reasoning format options
+   - Any new flags or parameters
+
+### Speculative Decoding Types
+
+The `spec_type` option in `grpc-server.cpp` delegates to upstream's `common_speculative_types_from_names()`, so new speculative types added to the `common_speculative_type_from_name` map in `common/speculative.cpp` are picked up automatically with no code changes - only docs need an entry in `docs/content/advanced/model-configuration.md`. Current values: `none`, `draft-simple`, `draft-eagle3`, `draft-mtp`, `ngram-simple`, `ngram-map-k`, `ngram-map-k4v`, `ngram-mod`, `ngram-cache`.
+
+`draft-mtp` (Multi-Token Prediction, [ggml-org/llama.cpp#22673](https://github.com/ggml-org/llama.cpp/pull/22673)) does not need a separate draft GGUF: when `spec_type` includes `draft-mtp` and `draftmodel` is empty, the upstream server creates an MTP context off the target model itself. LocalAI's gRPC layer needs no changes for this — it works through the existing `params.speculative.types` plumbing and the derived `cparams.n_rs_seq = params.speculative.need_n_rs_seq()` in `common_context_params_to_llama`.
+
+### Implementation Guidelines
+
+1. **Feature Parity**: Always aim for feature parity with llama.cpp's implementation
+2. **Test Coverage**: Add tests for new features matching llama.cpp's behavior
+3. **Documentation**: Update relevant documentation when adding new formats or options
+4. **Backward Compatibility**: Ensure changes don't break existing functionality
+
+### Files to Monitor
+
+- `llama.cpp/common/chat-parser-xml-toolcall.h` - Format definitions
+- `llama.cpp/common/chat-parser-xml-toolcall.cpp` - Parsing logic
+- `llama.cpp/common/chat-parser.cpp` - Format presets and model-specific handlers
+- `llama.cpp/common/chat.h` - Format enums and parameter structures
+- `llama.cpp/tools/server/server-context.cpp` - Server configuration options

+# 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.

+core/http/endpoints/mcp/
+  localai_assistant.go   # process-wide holder + LocalToolExecutor
+core/cli/mcp_server.go   # local-ai mcp-server subcommand
+```
+
+## 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.

+# Testing MCP Apps (Interactive Tool UIs)
+
+MCP Apps is an extension to MCP where tools declare interactive HTML UIs via `_meta.ui.resourceUri`. When the LLM calls such a tool, the UI renders the app in a sandboxed iframe inline in the chat. The app communicates bidirectionally with the host via `postMessage` (JSON-RPC) and can call server tools, send messages, and update model context.
+
+Spec: https://modelcontextprotocol.io/extensions/apps/overview
+
+## Quick Start: Run a Test MCP App Server
+
+The `@modelcontextprotocol/server-basic-react` npm package is a ready-to-use test server that exposes a `get-time` tool with an interactive React clock UI. It requires Node >= 20, so run it in Docker:
+
+```bash
+docker run -d --name mcp-app-test -p 3001:3001 node:22-slim \
+  sh -c 'npx -y @modelcontextprotocol/server-basic-react'
+```
+
+Wait ~10 seconds for it to start, then verify:
+
+```bash
+# Check it's running
+docker logs mcp-app-test
+# Expected: "MCP server listening on http://localhost:3001/mcp"
+
+# Verify MCP protocol works
+curl -s -X POST http://localhost:3001/mcp \
+  -H 'Content-Type: application/json' \
+  -H 'Accept: application/json, text/event-stream' \
+  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0.0"}}}'
+
+# List tools — should show get-time with _meta.ui.resourceUri
+curl -s -X POST http://localhost:3001/mcp \
+  -H 'Content-Type: application/json' \
+  -H 'Accept: application/json, text/event-stream' \
+  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'
+```
+
+The `tools/list` response should contain:
+```json
+{
+  "name": "get-time",
+  "_meta": {
+    "ui": { "resourceUri": "ui://get-time/mcp-app.html" }
+  }
+}
+```
+
+## Testing in LocalAI's UI
+
+1. Make sure LocalAI is running (e.g. `http://localhost:8080`)
+2. Build the React UI: `cd core/http/react-ui && npm install && npm run build`
+3. Open the Chat page in your browser
+4. Click **"Client MCP"** in the chat header
+5. Add a new client MCP server:
+   - **URL**: `http://localhost:3001/mcp`
+   - **Use CORS proxy**: enabled (default) — required because the browser can't hit `localhost:3001` directly due to CORS; LocalAI's proxy at `/api/cors-proxy` handles it
+6. The server should connect and discover the `get-time` tool
+7. Select a model and send: **"What time is it?"**
+8. The LLM should call the `get-time` tool
+9. The tool result should render the interactive React clock app in an iframe as a standalone chat message (not inside the collapsed activity group)
+
+## What to Verify
+
+- [ ] Tool appears in the connected tools list (not filtered — `get-time` is callable by the LLM)
+- [ ] The iframe renders as a standalone chat message with a puzzle-piece icon
+- [ ] The app loads and is interactive (clock UI, buttons work)
+- [ ] No "Reconnect to MCP server" overlay (connection is live)
+- [ ] Console logs show bidirectional communication:
+  - `tools/call` messages from app to host (app calling server tools)
+  - `ui/message` notifications (app sending messages)
+- [ ] After the app renders, the LLM continues and produces a text response with the time
+- [ ] Non-UI tools continue to work normally (text-only results)
+- [ ] Page reload shows the HTML statically with a reconnect overlay until you reconnect
+
+## Console Log Patterns
+
+Healthy bidirectional communication looks like:
+
+```
+Parsed message { jsonrpc: "2.0", id: N, result: {...} }     // Bridge init
+get-time result: { content: [...] }                          // Tool result received
+Calling get-time tool...                                     // App calls tool
+Sending message { method: "tools/call", ... }                // App -> host -> server
+Parsed message { jsonrpc: "2.0", id: N, result: {...} }     // Server response
+Sending message text to Host: ...                            // App sends message
+Sending message { method: "ui/message", ... }                // Message notification
+Message accepted                                             // Host acknowledged
+```
+
+Benign warnings to ignore:
+- `Source map error: ... about:srcdoc` — browser devtools can't find source maps for srcdoc iframes
+- `Ignoring message from unknown source` — duplicate postMessage from iframe navigation
+- `notifications/cancelled` — app cleaning up previous requests
+
+## Architecture Notes
+
+- **No server-side changes needed** — the MCP App protocol runs entirely in the browser
+- `PostMessageTransport` wraps `window.postMessage` between host and `srcdoc` iframe
+- `AppBridge` (from `@modelcontextprotocol/ext-apps`) auto-forwards `tools/call`, `resources/read`, `resources/list` from the app to the MCP server via the host's `Client`
+- The iframe uses `sandbox="allow-scripts allow-forms"` (no `allow-same-origin`) — opaque origin, no access to host cookies/DOM/localStorage
+- App-only tools (`_meta.ui.visibility: "app-only"`) are filtered from the LLM's tool list but remain callable by the app iframe
+
+## Key Files
+
+- `core/http/react-ui/src/components/MCPAppFrame.jsx` — iframe + AppBridge component
+- `core/http/react-ui/src/hooks/useMCPClient.js` — MCP client hook with app UI helpers (`hasAppUI`, `getAppResource`, `getClientForTool`, `getToolDefinition`)
+- `core/http/react-ui/src/hooks/useChat.js` — agentic loop, attaches `appUI` to tool_result messages
+- `core/http/react-ui/src/pages/Chat.jsx` — renders MCPAppFrame as standalone chat messages
+
+## Other Test Servers
+
+The `@modelcontextprotocol/ext-apps` repo has many example servers:
+- `@modelcontextprotocol/server-basic-react` — simple clock (React)
+- More examples at https://github.com/modelcontextprotocol/ext-apps/tree/main/examples
+
+All examples support both stdio and HTTP transport. Run without `--stdio` for HTTP mode on port 3001.
+
+## Cleanup
+
+```bash
+docker rm -f mcp-app-test
+```

+# 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:
+
+```go
+// core/config/hooks_<backend>.go
+func init() {
+    RegisterBackendHook("<backend>", myDefaults)
+}
+func myDefaults(cfg *ModelConfig, modelPath string) {
+    // only fill in fields the user didn't set
+}
+```
+
+## 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()`.

+name: 'Configure apt mirror'
+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.

+
+            Maintainers (owner / member / collaborator) can control this PR
+            by leaving a comment with one of:
+
+            - `/gallery-agent recreate` — close this PR; the next scheduled
+              run will propose this model again (useful if the entry needs
+              to be regenerated with fresh metadata).
+            - `/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
+            model may be reproposed by a future run.
+
+            **Workflow Details:**
+            - Triggered by: `${{ github.event_name }}`
+            - Run ID: `${{ github.run_id }}`
+            - Commit: `${{ github.sha }}`

+# LocalAI Agent Instructions
+
+This file is the entry point for AI coding assistants (Claude Code, Cursor, Copilot, Codex, Aider, etc.) working on LocalAI. It is an index to detailed topic guides in the `.agents/` directory. Read the relevant file(s) for the task at hand — you don't need to load all of them.
+
+Human contributors: see [CONTRIBUTING.md](CONTRIBUTING.md) for the development workflow.
+
+## Policy for AI-Assisted Contributions
+
+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
+
+- **Logging**: Use `github.com/mudler/xlog` (same API as slog)
+- **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

 ### Prerequisites
 
-- Golang [1.21]
-- Git
-- macOS/Linux
+- **Go 1.21+** (the project currently uses Go 1.26 in `go.mod`, but 1.21 is the minimum supported version)
+  - [Download Go](https://go.dev/dl/) or install via your package manager
+  - macOS: `brew install go`
+  - Ubuntu/Debian: follow the [official instructions](https://go.dev/doc/install) (the `apt` version is often outdated)
+  - Verify: `go version`
+- **Git**
+- **GNU Make**
+- **GCC / C/C++ toolchain** (required for CGo and native backends)
+- **Protocol Buffers compiler** (`protoc`) — needed for gRPC code generation

+
+</details>
+
+### Setting up the Development Environment
+
+1. **Clone the repository:**
+
+   ```bash
+   git clone https://github.com/mudler/LocalAI.git
+   cd LocalAI
+   ```
+
+2. **Build LocalAI:**
+
+   ```bash
+   make build
+   ```
+
+   This runs protobuf generation, installs Go tools, builds the React UI, and compiles the `local-ai` binary. Key build variables you can set:
+
+   | Variable | Description | Example |
+   |---|---|---|
+   | `BUILD_TYPE` | GPU/accelerator type (`cublas`, `hipblas`, `intel`, ``) | `BUILD_TYPE=cublas make build` |
+   | `GO_TAGS` | Additional Go build tags | `GO_TAGS=debug make build` |
+   | `CUDA_MAJOR_VERSION` | CUDA major version (default: `13`) | `CUDA_MAJOR_VERSION=12` |
+
+3. **Run LocalAI:**
+
+   ```bash
+   ./local-ai
+   ```
+
+4. **Development mode with live reload:**
+
+   ```bash
+   make build-dev
+   ```
+
+   This installs [`air`](https://github.com/air-verse/air) automatically and watches for file changes, rebuilding and restarting the server on each save.
+
+5. **Containerized build** (no local toolchain needed):
+
+   ```bash
+   make docker
+   ```
+
+   For GPU-specific Docker builds, see the `docker-build-*` targets in the Makefile and refer to [CLAUDE.md](CLAUDE.md) for detailed backend build instructions.
+
+### Environment Variables
+
+LocalAI is configured primarily through environment variables (or equivalent CLI flags). The most useful ones for development are:
+
+| Variable | Description | Default |
+|---|---|---|
+| `LOCALAI_DEBUG` | Enable debug mode | `false` |
+| `LOCALAI_LOG_LEVEL` | Log verbosity (`error`, `warn`, `info`, `debug`, `trace`) | — |
+| `LOCALAI_LOG_FORMAT` | Log format (`default`, `text`, `json`) | `default` |
+| `LOCALAI_MODELS_PATH` | Path to model files | `./models` |
+| `LOCALAI_BACKENDS_PATH` | Path to backend binaries | `./backends` |
+| `LOCALAI_CONFIG_DIR` | Directory for dynamic config files (API keys, external backends) | `./configuration` |
+| `LOCALAI_THREADS` | Number of threads for inference | — |
+| `LOCALAI_ADDRESS` | Bind address for the API server | `:8080` |
+| `LOCALAI_API_KEY` | API key(s) for authentication | — |
+| `LOCALAI_CORS` | Enable CORS | `false` |
+| `LOCALAI_DISABLE_WEBUI` | Disable the web UI | `false` |
+
+See `core/cli/run.go` for the full list of supported environment variables.

-### Creating a Pull Request (PR)
+### Development Workflow
+
+#### Branch naming conventions
+
+Use a descriptive branch name that indicates the type and scope of the change:
+
+- `feature/<short-description>` — new functionality
+- `fix/<short-description>` — bug fixes
+- `docs/<short-description>` — documentation changes
+- `refactor/<short-description>` — code refactoring
+
+#### Commit messages
+
+- Use a short, imperative subject line (e.g., "feat: add whisper backend support", not "Added whisper backend support")
+- Keep the subject under 72 characters
+- Use the body to explain **why** the change was made when the subject alone is not sufficient
+- Use [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/)
+
+#### Creating a Pull Request (PR)
+
+Before jumping into a PR for a massive feature or big change, it is preferred to discuss it first via an issue.
 
 1. Fork the repository.
-2. Create a new branch with a descriptive name: `git checkout -b [branch name]`
-3. Make your changes and commit them.
-4. Push the changes to your fork: `git push origin [branch name]`
-5. Create a new pull request from your branch to the main project's `main` or `master` branch.
-6. Provide a clear description of your changes in the pull request.
-7. Make any requested changes during the review process.
-8. Once your PR is approved, it will be merged into the main project.
+2. Create a new branch: `git checkout -b feature/my-change`
+3. Make your changes, keeping commits focused and atomic.
+4. Run tests locally before pushing (see [Testing](#testing) below).
+5. Push to your fork: `git push origin feature/my-change`
+6. Open a pull request against the `master` branch.
+7. Fill in the PR description with:
+   - What the change does and why
+   - How it was tested
+   - Any breaking changes or migration steps
+8. Respond to review feedback promptly. Push follow-up commits rather than force-pushing amended commits so reviewers can see incremental changes.
+9. Once approved, a maintainer will merge your PR.
 
 ## Coding Guidelines
 
-- No specific coding guidelines at the moment. Please make sure the code can be tested. The most popular lint tools like [`golangci-lint`](https://golangci-lint.run) can help you here.
+This project uses an [`.editorconfig`](.editorconfig) file to define formatting standards (indentation, line endings, charset, etc.). Please configure your editor to respect it.
+
+For AI-assisted development, see [`AGENTS.md`](AGENTS.md) (or the equivalent [`CLAUDE.md`](CLAUDE.md) symlink) for agent-specific guidelines including build instructions and backend architecture details. Contributions produced with AI assistance must follow the rules in the [AI Coding Assistants](#ai-coding-assistants) section below.
+
+### General Principles
+
+- Write code that can be tested. All new features and bug fixes should include test coverage.
+- Use comments sparingly to explain **why** code does something, not **what** it does. Comments should add context that would be difficult to deduce from reading the code alone.
+- Keep changes focused. Avoid unrelated refactors, formatting changes, or feature additions in the same PR.
+
+### Go Code
+
+- Prefer modern Go idioms — for example, use `any` instead of `interface{}`.
+- Use [`golangci-lint`](https://golangci-lint.run) to catch common issues before submitting a PR.
+- Use [`github.com/mudler/xlog`](https://github.com/mudler/xlog) for logging (same API as `slog`). Do not use `fmt.Println` or the standard `log` package for operational logging.
+- Use tab indentation for Go files (as defined in `.editorconfig`).
+
+### Python Code
+
+- Use 4-space indentation (as defined in `.editorconfig`).
+- Include a `requirements.txt` for any new dependencies.
+
+### Code Review
+
+- All contributions go through code review via pull requests.
+- Reviewers will check for correctness, test coverage, adherence to these guidelines, and clarity of intent.
+- Be responsive to review feedback and keep discussions constructive.
+
+## 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
 
-`make test` cannot handle all the model now. Please be sure to add a test case for the new features or the part was changed.
+All new features and bug fixes should include test coverage. The project uses [Ginkgo](https://onsi.github.io/ginkgo/) as its test framework.
 
-### Running AIO tests
+### Running unit tests
 
-All-In-One images has a set of tests that automatically verifies that most of the endpoints works correctly, a flow can be :
+```bash
+make test
+```
+
+This downloads test model fixtures, runs protobuf generation, and executes the full test suite including llama-gguf, TTS, and stable-diffusion tests. Note: some tests require model files to be downloaded, so the first run may take longer.
+
+To run tests for a specific package:
+
+```bash
+go test ./core/config/...
+go test ./pkg/model/...
+```
+
+To run a specific test by name using Ginkgo's `--focus` flag:
+
+```bash
+go run github.com/onsi/ginkgo/v2/ginkgo --focus="should load a model" -v -r ./core/
+```
+
+### Running end-to-end tests
+
+The e2e tests run LocalAI in a Docker container and exercise the API:
+
+```bash
+make test-e2e
+```
+
+### Running E2E container tests
+
+These tests build a standard LocalAI Docker image and run it with pre-configured model configs to verify that most endpoints work correctly:
 
 ```bash
 # Build the LocalAI docker image
-make DOCKER_IMAGE=local-ai docker
+make docker-build-e2e
 
-# Build the corresponding AIO image
-BASE_IMAGE=local-ai DOCKER_AIO_IMAGE=local-ai-aio:test make docker-aio
+# Run the e2e tests (uses model configs from tests/e2e-aio/models/)
+make e2e-aio
+```
 
-# Run the AIO e2e tests
-LOCALAI_IMAGE_TAG=test LOCALAI_IMAGE=local-ai-aio make run-e2e-aio
+### Testing backends
+
+To prepare and test extra (Python) backends:
+
+```bash
+make prepare-test-extra   # build Python backends for testing
+make test-extra           # run backend-specific tests
 ```

+We welcome contributions to the documentation. Please open a new PR or create a new issue. The documentation is available under `docs/` https://github.com/mudler/LocalAI/tree/master/docs
+
+### Gallery YAML Schema
+
+LocalAI provides a JSON Schema for gallery model YAML files at:
+
+`core/schema/gallery-model.schema.json`
+
+This schema mirrors the internal gallery model configuration and can be used by editors (such as VS Code) to enable autocomplete, validation, and inline documentation when creating or modifying gallery files.
+
+To use it with the YAML language server, add the following comment at the top of a gallery YAML file:
+
+```yaml
+# yaml-language-server: $schema=../core/schema/gallery-model.schema.json
+```

 We provide support and updates for certain versions of our software. The following table outlines which versions are currently supported with security updates:
 
-| Version | Supported          |
-| ------- | ------------------ |
-| > 2.0   | :white_check_mark: |
-| < 2.0   | :x:                |
+| Version Series | Support Level | Details |
+| -------------- | ------------- | ------- |
+| 3.x | :white_check_mark: Actively supported | Full security updates and bug fixes for the latest minor versions. |
+| 2.x | :warning: Security fixes only | Critical security patches only, until **December 31, 2025**. |
+| 1.x | :x: End-of-life (EOL) | No longer supported as of **January 1, 2024**. No security fixes will be provided. |
+
+### What each support level means
+
+- **Actively supported (3.x):** Receives all security updates, bug fixes, and new features. Users should stay on the latest 3.x minor release for the best protection.
+- **Security fixes only (2.x):** Receives only critical security patches (e.g., remote code execution, authentication bypass, data exposure). No bug fixes or new features. Support ends December 31, 2025.
+- **End-of-life (1.x):** No updates of any kind. Users on 1.x are strongly encouraged to upgrade immediately, as known vulnerabilities will not be patched.
+
+### Migrating from older versions
+
+If you are running an unsupported or soon-to-be-unsupported version, we recommend upgrading as soon as possible:
+
+- **From 1.x to 3.x:** Version 1.x reached end-of-life on January 1, 2024. Review the [release notes](https://github.com/mudler/LocalAI/releases) for breaking changes across major versions, and upgrade directly to the latest 3.x release.
+- **From 2.x to 3.x:** While 2.x still receives critical security patches until December 31, 2025, we recommend planning your migration to 3.x to benefit from ongoing improvements and full support.
 
 Please ensure that you are using a supported version to receive the latest security updates.
