Make AI run onevery machine.
Text, voice, vision, images, video, 3D and agents, from one open runtime. It works on the laptop you already own, and scales to a room full of GPUs when you have one. When the engine we need is too heavy, too closed, or does not exist, we write it.
Engines we build
Eighteen engines, written from scratch.
Most backends wrap somebody else's engine. These do not. They exist because the thing we needed was a 9 GB Python install, or closed, or nobody had built it yet. Each one is a binary and a GGUF file, checked against the reference implementation in CI.
parakeet.cpp
Twenty-seven times faster than whisper.cpp, on a CPU.
NVIDIA NeMo Parakeet, ported to C++ and ggml. Ten checkpoints, all of them verified at WER 0 against NeMo, which means the transcript comes out byte for byte identical while finishing first. Cache-aware streaming with end-of-utterance detection handles live audio, and the multilingual streaming model covers 40 or more locales.
depth-anything.cpp
Beats PyTorch on CPU, in half the memory.
Depth Anything 3 as a 99 MB file. It gives you metric depth, per-pixel confidence, camera intrinsics and extrinsics, and a back-projected point cloud you can export to glb or COLMAP. Output correlates 1.0 with the reference implementation, component by component, and there is no Python or CUDA toolkit anywhere at inference.
And the rest of them, running.
Every clip comes out of the benchmark suite that runs in CI on that engine. Where you see two panes, ours is racing the reference implementation on the same machine, on the same input.
In development, not announced yet
vllm.cpp
vLLM ported to C++20, with paged attention, continuous batching and prefix caching, on CPU, CUDA, Metal and Vulkan. It installs as 66 MB instead of a 9.1 GB virtualenv, and it stays ahead of vLLM at every concurrency level we have measured so far. Still being finished, so treat the numbers as provisional.
APEX quantization
The model you could not fit, on the card you already own.
A 35B mixture-of-experts model is 64.6 GB at full precision, which puts it out of reach of every consumer GPU. APEX gets it to 12.2 GB, and it runs at 74 tokens a second, more than twice the speed of the original. Quality barely moves. The file is an ordinary GGUF, so stock llama.cpp opens it with no patches, and 201 of them are already sitting in the LocalAI gallery.

nib
An agent you can drop on any box you SSH into.
One Go binary, about 20 MB, no runtime and no daemon. Press Ctrl+Space anywhere and it opens. Point it at any OpenAI-compatible endpoint, including a model running on your own laptop, and it works. Tool calls go through an approval gate you control, and Claude Code plugins load as they are.
Since March 2023
Forty-eight thousand stars, and still shipping every week.
LocalAI has been trending on GitHub repeatedly since it launched, and it is one of the most starred self-hosted AI projects there is. 224 people have contributed code, 3,187 are in the Discord, and the README is kept translated into eight languages because the users are everywhere.
MAR 2023
First commit
An OpenAI-compatible API in front of llama.cpp, so a laptop could answer the same calls as the cloud.
JUL 2025
The core gets small
Every backend moves out of the binary. You install only the engines your models need.
MAR 2026
Agents and a new interface
Native agentic orchestration, a full React rewrite with canvas mode, WebRTC realtime audio.
APR 2026
It becomes a cluster
Distributed mode with VRAM-aware routing, autoscaling, multi-user auth and per-user quotas.
MAY 2026
It sees and hears
Voice recognition, face recognition with liveness, diarization, video generation, drop-in Ollama API.
JUL 2026
Nineteen engines of our own
The native C and C++ ports take over the heavy Python backends, one modality at a time.

LocalAI is becoming stronger and better release, after release! Keep pushing @mudler_it and @LocalAI_API
On X, 2026 ↗@alepiad early days
I'm really excited about the prospect of open-source LLMs. In that respect, take a look at @LocalAI_API, a drop-in replacement for OpenAI's API but serving GGML models right on your own infrastructure.

Oh, high there @LocalAI_API, nice to see a terminal based UI for ya! (it's a WIP, but just wanted something cleaner then CURL calls)
On X, 2023 ↗From the team
We publish the numbers, including the ones that cost us.
APEX takes a 35B model from 64.6 GB to 12.2 GB, and from 30.4 to 74.4 tokens a second. Perplexity goes from 6.537 to 7.088. That trade is in the post too, with the command that produced it.
