fix(llama-cpp): default rms_norm_eps for Gemma 3 GGUFs missing the key

Some Gemma 3 GGUF files distributed via the Ollama registry omit the
`gemma3.attention.layer_norm_rms_epsilon` metadata key. Both llama.cpp
and ik_llama.cpp treat that key as required and abort the load with:

    error loading model hyperparameters:
    key not found in model: gemma3.attention.layer_norm_rms_epsilon

Ollama's loader silently falls back to ~1e-6 in the same situation,
which is the canonical Gemma 3 default (google/gemma_pytorch config.py
and the Hugging Face Gemma3Config), and the model loads correctly.

Add small build-time patches to both backends that pre-seed
`hparams.f_norm_rms_eps` with 1e-6 and mark the metadata lookup as
optional. GGUFs that already carry the key continue to use the embedded
value unchanged.

Closes #9414

+## 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.

+# 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

+# 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 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()`.

+            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

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

-> Note: the DMGs are not signed by Apple as quarantined. See https://github.com/mudler/LocalAI/issues/6268 for a workaround, fix is tracked here: https://github.com/mudler/LocalAI/issues/6244
-> Install the DMG and paste this code into terminal: `sudo xattr -d com.apple.quarantine /Applications/LocalAI.app`
+> **Note:** The DMG is not signed by Apple. After installing, run: `sudo xattr -d com.apple.quarantine /Applications/LocalAI.app`. See [#6268](https://github.com/mudler/LocalAI/issues/6268) for details.
 
 ### Containers (Docker, podman, ...)
 
-> **💡 Docker Run vs Docker Start**
-> 
-> - `docker run` creates and starts a new container. If a container with the same name already exists, this command will fail.
-> - `docker start` starts an existing container that was previously created with `docker run`.
-> 
-> If you've already run LocalAI before and want to start it again, use: `docker start -i local-ai`
+> Already ran LocalAI before? Use `docker start -i local-ai` to restart an existing container.

+From: LocalAI maintainers <noreply@localai.io>
+Subject: [PATCH] gemma3: default rms norm eps when GGUF metadata key is missing
+
+Some Gemma 3 GGUF files (notably those distributed via the Ollama
+registry) do not embed the `gemma3.attention.layer_norm_rms_epsilon`
+metadata key. ik_llama.cpp currently requires the key to be present and
+fails the entire model load with:
+
+    error loading model hyperparameters:
+    key not found in model: gemma3.attention.layer_norm_rms_epsilon
+
+Ollama's own loader silently falls back to ~1e-6 in the same situation,
+which is the canonical Gemma 3 default (see google/gemma_pytorch
+config.py and the Hugging Face Gemma3Config), so the model still loads
+and works correctly.

+From: LocalAI maintainers <noreply@localai.io>
+Subject: [PATCH] gemma3: default rms norm eps when GGUF metadata key is missing
+
+Some Gemma 3 GGUF files (notably those distributed via the Ollama
+registry) do not embed the `gemma3.attention.layer_norm_rms_epsilon`
+metadata key. llama.cpp currently requires the key to be present and
+fails the entire model load with:
+
+    error loading model hyperparameters:
+    key not found in model: gemma3.attention.layer_norm_rms_epsilon
+
+Ollama's own loader silently falls back to ~1e-6 in the same situation,
+which is the canonical Gemma 3 default (see google/gemma_pytorch
+config.py and the Hugging Face Gemma3Config), so the model still loads
+and works correctly.
+
+Mirror that behavior here: pre-seed the field with the Gemma 3 default
+and mark the metadata key as optional. This unblocks Ollama-converted
+Gemma 3 models without affecting GGUFs that already carry the key.

+    tinygrad is a minimalist deep-learning framework with zero runtime
+    dependencies that targets CUDA, ROCm, Metal, WebGPU and CPU (CLANG).
+    The LocalAI tinygrad backend exposes a single multimodal runtime that
+    covers LLM text generation (Llama / Qwen / Mistral via safetensors or
+    GGUF) with native tool-call extraction, BERT-family embeddings,
+    Stable Diffusion 1.x / 2 / XL image generation, and Whisper speech-to-text.
+
+    Single image: tinygrad generates its own GPU kernels and dlopens the
+    host driver libraries at runtime, so there is no per-toolkit build
+    split. The same image runs CPU-only or accelerates against
+    CUDA / ROCm / Metal when the host driver is visible.
