Ettore Di Giacinto 5880f4e6dd test(distributed): pin the no-demotion rule at every call site it is stated
Review fix round 1. Two blocking findings and seven non-blocking; both
blocking ones are M12's shape again, and this time on the invariant
itself. No production behaviour changes here: everything below was
already correct and merely unpinned, so re-inserting the defect left all
679 specs green. The only non-comment edits are one struct-field comment
and one log message.

"A failed control RPC no longer demotes a node" is stated three times in
this package and was pinned once, at ListBackends. Putting MarkUnhealthy
back at either op-drain site passed. What that buys in production is the
fleet-wide eviction this phase exists to prevent: MarkUnhealthy removes a
node from ListDuePendingBackendOps AND from scheduling, so a frontend
replica that has just lost its tunnels demotes every node it holds an op
for, for a reason that is about the frontend. The reconciler's is the
worse of the two, being a background loop nobody is watching. Both now
have a spec, each with the recorded op failure as its negative control so
"still healthy" cannot pass by nothing having happened.

The sweep the review asked for found four more rules stated at more call
sites than they were pinned at, and two the review had not:

The still-installing surfacing at the manager layer has two call sites
and was pinned at InstallBackend. Dropping it from UpgradeBackend
reported a spent budget as GREEN SUCCESS: the admin sees the upgrade
finished while the worker is still re-pulling gigabytes.

The agent-node skip has two call sites and was pinned at ListBackends.
Without it the fan-out enqueues a row for every agent node, and an agent
worker serves no control plane, so that row can never drain: it retries
until the dead-letter cap.

The still-installing conversion has three call sites and was pinned at
two; the legacy force-install fallback was the gap. Its budget was
unpinned too, so the new spec asserts both, on the upgrade budget rather
than the install one, since the fallback re-fires an install as part of
an upgrade.

The carrier split has two call sites and was pinned at one. Hardcoding
NodeTypeBackend in UnloadRemoteModelContext passed, and an agent node
holding a node_models row would then have its stop sent over a tunnel it
does not hold, fail, and leave the row behind. The new spec unloads a
model held by one node of each kind and asserts each stop went to that
node's own carrier and to no other.

router_nats_liveness_test.go asserted demote-on-absence, which production
can no longer produce, and its header described the pre-cutover world.
The exclusion is unreachable by construction rather than by argument:
cluster, the package supplying every control-path dial error, does not
link nats.go at all. The file now says that, and gains the assertion that
IS load-bearing, a table naming each sentinel a control RPC can answer
with and requiring that none of them excludes. Widening the exclusion to
ErrWorkerUnroutable reddens four of its entries plus the real-adapter
scheduling spec.

unroutable keeps no budget-first guard and the reason is now written at
it: unlike controlFailure it reads one already-recorded error rather than
racing a live deadline, and an expiry is not in streamRefusals, so it
falls to the umbrella without one. The two implement the same split at
two layers and each now names the other.

Fourteen comments still described the bus. Among them the reconciler
saying a drain would "churn NATS every tick", a spec comment naming a
subject builder this branch deleted, and the agent-skip comment
explaining the skip by a subscription that no longer exists.

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

Automatic Backend Detection: LocalAI automatically detects your GPU capabilities and downloads the appropriate backend. For advanced options, see GPU Acceleration.

Features

Supported Backends & Acceleration

LocalAI supports 60+ backends including llama.cpp, vLLM, SGLang, transformers, whisper.cpp, diffusers, MLX, MLX-VLM, and many more. Hardware acceleration is available for NVIDIA (CUDA 12/13), AMD (ROCm), Intel (oneAPI/SYCL), Apple Silicon (Metal), Vulkan, and NVIDIA Jetson (L4T). All backends can be installed on-the-fly from the Backend Gallery.

See the full Backend & Model Compatibility Table and GPU Acceleration guide.

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
parakeet.cpp C++/GGML port of NVIDIA NeMo Parakeet ASR (tdt/ctc/rnnt/hybrid), with cache-aware streaming transcription
moss-transcribe.cpp C++/GGML port of OpenMOSS MOSS-Transcribe-Diarize: joint long-form transcription, speaker diarization and timestamping in a single pass
moss-tts.cpp C++/GGML port of the OpenMOSS MOSS-TTS family: text-to-speech (MOSS-TTS-Local v1.5, 48 kHz stereo) with reference-audio voice cloning, through the MOSS-Audio-Tokenizer neural codec
magpie-tts.cpp C++/GGML port of NVIDIA's Magpie TTS Multilingual 357M: 22.05 kHz mono text-to-speech in 5 voices and 9+ languages, with the NanoCodec neural codec and tokenizer/G2P embedded in a single GGUF
ced.cpp C++/GGML port of the CED audio-tagging models: sound-event classification (527-class AudioSet) over REST and the realtime API for live recognition
voice-detect.cpp Speaker recognition and voice analysis (ECAPA-TDNN, WeSpeaker, ERes2Net, CAM++, wav2vec2 age/gender/emotion), replacing the Python speaker-recognition backend
voxtral-tts.c Mistral Voxtral-4B-TTS text-to-speech in pure C: 20 preset voices across 9 languages, 24 kHz WAV output, no dependencies beyond libc
vibevoice.cpp Native port of Microsoft VibeVoice for TTS (voice cloning) and long-form ASR with speaker diarization
rf-detr.cpp Native RF-DETR object detection and instance segmentation
locate-anything.cpp Open-vocabulary object detection and visual grounding (LocateAnything-3B)
depth-anything.cpp Depth Anything 3 monocular metric depth + camera pose estimation
face-detect.cpp Face detection, recognition, demographics and anti-spoofing (SCRFD/ArcFace, YuNet/SFace), replacing the Python insightface backend
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)
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.
