LocalAI
Free, open source OpenAI alternative that runs locally
LocalAI is the free, open-source drop-in replacement for OpenAI, Claude, and other commercial AI APIs. Run LLMs, generate images, transcribe audio, and create embeddings—all locally without GPU requirement. OpenAI-compatible API means zero code changes to switch from cloud to local inference.
Why LocalAI?
Cloud AI APIs are expensive and require sending your data to third parties. OpenAI charges per token, and your queries are logged on their servers. For privacy-sensitive applications or cost-conscious teams, this creates real problems. You need local inference that doesn't require expensive GPUs or complex setup.
How It Works
LocalAI provides an OpenAI-compatible API that runs entirely on your hardware—even without a GPU. Point your existing code at LocalAI instead of OpenAI, and it just works. The same API handles text generation, image creation, speech-to-text, and embeddings. Automatic GPU detection accelerates inference when available.
What Is LocalAI?
LocalAI is a self-hosted AI inference server compatible with OpenAI's API. It supports text generation (llama.cpp, vLLM), image generation (Stable Diffusion), audio transcription (Whisper), text-to-speech, embeddings, and multimodal models. Runs on CPU or GPU with automatic hardware detection.
