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

Loading models

# From the model gallery (see available models with `local-ai models list` or at https://models.localai.io)
local-ai run llama-3.2-1b-instruct:q4_k_m

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.

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)
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.
