mudler-agentandEttore Di Giacinto c7ce0c602c fix: stop listing the models directory on request paths and cache GGUF header reads (#12683)
* fix(http): stop listing the models directory on embeddings and bearer requests

Every embeddings request read the whole models directory before the body
was parsed, even when the body named its model. On a network-backed
models directory this cost seconds per request.

Embeddings now binds the body first and looks up a default model only
when the body has none, like chat. The pre-bind default lookup and the
gpt-4o constant default are gone from that route.

The first-available default lookup skips the directory when the filter
cannot accept an unconfigured file. Every usecase filter rejects files
without a config, so the scan never added results for them. Match-all,
nil and name filters keep the scan.

The bearer token check is now an exact test: a configured name, or one
stat of that name in the models directory. The value is a literal, not a
regular expression, and a name that is not a local relative path never
matches a file.

* perf(config): cache GGUF header reads for model defaults

Model defaults re-parsed the GGUF header on every SetDefaults call, which
runs per request and at startup reload. Put a bounded LRU in front of the
parser, keyed by absolute path and validated by size and modification
time. The cached value is a snapshot of the fields the defaults use, not
the parser output.

A changed size or mtime is a miss. Missing files and parse errors are not
cached, so the existing fallback is unchanged. LOCALAI_DISABLE_GUESSING,
the empty-path guard, the alias early return, the panic recovery and the
context-size default are all kept in front of the cache.

* test(http): cover listing-free default lookup on every usecase route

Assisted-by: Claude Code:claude-haiku-5-5

* feat(config): persist the GGUF header cache per instance

The header cache kept parsed GGUF results only in memory, so every restart
parsed each model file again before its defaults were known. Write the cache
to a per-instance file in the data path and load it at startup. A restarted
frontend with a fixed instance ID starts warm.

The file is versioned and records the estimator inputs (gguf-parser version,
candidate contexts, auto context size, offload count). A mismatch on any of
them makes the file ignored. Each entry keeps path, size and mtime, so a
changed model file is a miss on load. Writes run on one background saver,
debounced, through a temp file and rename. The entry bound applies to the
file as well. Without a data path the cache stays in memory only.

Documented as a per-instance exception in the model configuration docs.

* docs(embeddings): document model selection and the no-model error

Assisted-by: Claude Code:claude-haiku-5-5

* refactor(config): split the header cache into a generic cache

The GGUF header cache mixed two things: the mechanics (bounded LRU keyed
by path and identity, per-instance file, debounced atomic save, tolerant
load) and the GGUF fields. Move the mechanics into headerCache[S], driven
by a headerCacheSpec[S] that names the file prefix, schema, fingerprint,
parser and the snapshot encode/decode pair. The GGUF cache becomes one
instance of it.

File names, the identity check, LRU size, debounce, atomic write and the
corruption handling are unchanged. The on-disk JSON keeps the "estimator"
key so existing files still load.

Assisted-by: Claude Code:claude-haiku-5-5

* feat(config): share one GGUF header cache file between frontends

Every frontend used to write its own header cache file, named after its
instance ID, so a header read by one frontend was never reused by another.
The cache now uses one file, header-cache.json, in the data path, for all
frontends and for standalone mode. The instance ID no longer changes the
file name.

Frontends share the file in three ways. A save first merges the file's
entries in, so one frontend's write does not drop another's entries. A
miss reloads the file when its modification time has changed, and a hit
never reads it. Writes go to a temp file that is renamed into place, so a
reader never sees a partial file.

Two frontends saving at the same moment can still drop each other's last
entries. That costs one re-parse, never a wrong value, because every
entry is checked against its model file before use.

The shared file is valid only when every frontend mounts the same data
volume. The distributed-mode and model-configuration docs state this mode
and its volume limit.

LocalAI is the open-source AI engine. Run any model - LLMs, vision, voice, image, video - on any hardware. No GPU required.

A small core, not a bundle. Each backend wraps a best-in-class engine (llama.cpp, vLLM, whisper.cpp, stable-diffusion, MLX...) in its own image, pulled only when a model needs it. You install nothing you don't use.

  • Composable by design: backends are separate and pulled on demand, so you install only what your model needs
  • Open and extensible: load any model, or build your own backend in any language against an open interface
  • Drop-in API compatibility: OpenAI, Anthropic, and ElevenLabs APIs across every backend
  • Any model, any modality: LLMs, vision, voice, image, and video behind one API
  • Any hardware: NVIDIA, AMD, Intel, Apple Silicon, Vulkan, or CPU-only
  • Multi-user ready: API key auth, user quotas, role-based access
  • Built-in AI agents: autonomous agents with tool use, RAG, MCP, and skills
  • Privacy-first: your data never leaves your infrastructure

A small LocalAI core with backends (llama.cpp, vLLM, MLX, whisper.cpp, stable-diffusion, kokoro, parakeet.cpp...) plugged in as separate on-demand images

To work with a running LocalAI server from the terminal, start the built-in agent from another shell. It answers questions, reads your files and runs commands on your machine, asking you to approve anything that changes state. Inside a session, /models lists installed models and /model <name> switches between them. See the Terminal agent docs.

# Terminal 1
local-ai run llama-3.2-1b-instruct:q4_k_m

# Terminal 2
local-ai chat --model llama-3.2-1b-instruct:q4_k_m

Backends built by us

Most backends wrap a best-in-class upstream engine. A handful of them are native C/C++/GGML engines (no Python at inference) developed and maintained by the LocalAI project itself:

Backend What it does
vllm.cpp From-scratch C++20 port of vLLM for text generation: paged KV cache, continuous batching, prefix caching, safetensors + GGUF loading, engine-enforced structured output, on CPU, CUDA, Metal and Vulkan. Also serves MiniMax-H3 joint video+audio generation

free-splatter.cpp Pose-free 3D reconstruction (FreeSplatter): turns a handful of plain photos into 3D Gaussians, no camera poses or GPU required
trellis2.cpp C++/GGML port of Microsoft TRELLIS.2: single-image to textured 3D mesh (GLB with PBR materials)
gem-x.cpp Live human motion capture with SOMA and SMPL pose streams (CPU/Vulkan)
kimodo.cpp C++/GGML text-to-motion on CPU and Vulkan, exported as animated skeleton GLB
privacy-filter.cpp Standalone GGML PII/NER token-classification engine powering LocalAI's PII redaction tier
LocalVQE Joint acoustic echo cancellation, noise suppression, and dereverberation
local-store Local-first vector database for embeddings (shipped in-tree)

We also maintain apex-quant, a per-tensor, per-layer quantization recipe for Mixture-of-Experts models that exploits their structural sparsity to produce GGUFs matching or beating Q8_0 quality - and they run out of the box on stock llama.cpp.
