LocalAI

mudler

The OpenAI-compatible API you run yourself: drop in GGUF or other local backends, keep the same SDK, and never send the prompt off the machine.

Product preview

Overview

LocalAI is the drop-in that lets an existing OpenAI client talk to hardware you own: same base URL shape, local weights, no vendor. Ollama is friendlier as a daemon-plus-CLI; Jan and LM Studio are friendlier as apps. LocalAI is friendlier as a server you put behind your own tools, including image and audio endpoints that those apps treat as extras.

You will operate it. Models, GPUs, and the gap between “OpenAI-compatible” and “this one path 404s” are yours. For air-gapped stacks that already speak the OpenAI SDK, it is the least-rewrite local gateway.

Pros / Cons

Pros

OpenAI SDK keeps working against localhost
More than chat: images, audio, embeddings
MIT, Docker-native, no account
Fits air-gapped and self-hosted stacks

Cons

You operate the models and the GPUs
Compatibility is 'most paths', not a contract
Less friendly than LM Studio for humans at a keyboard
