What is LocalAI?
LocalAI is an open-source AI runtime that serves language, image, audio and embedding models on your own hardware behind APIs that mimic OpenAI and other cloud services, and it runs on CPUs when no GPU is available.
LocalAI bundles more than 60 back ends behind one server and one model gallery, which lists more than 1,200 models according to its website. It runs on x86_64 and ARM64, with optional acceleration through CUDA, ROCm, SYCL, Metal and Vulkan. Built-in agents with tool use, RAG, MCP and skills are part of the server, and the website also names the companion projects LocalAGI and LocalRecall. The project is MIT licensed; according to the README it is maintained by a small team together with the community, and the website counts more than 245 contributors. The GitHub API showed about 49,000 stars and a push on September 28, 2026.
LocalAI AI features and use cases
- Replaces several cloud APIs at onceLocalAI answers requests in the formats of OpenAI, Anthropic, Ollama and ElevenLabs. Teams that use several cloud services for text and voice can test one self-hosted server as a substitute.
- Covers text, images and speechThe runtime handles chat with tool calling, image and video generation, speech synthesis, voice cloning and transcription with speaker labels. Small IT teams get one platform for several AI use cases.
- Runs agents with local toolsBuilt-in agents use tools, RAG, MCP servers and skills, and a terminal agent works with files and commands after the user approves changes. Automation can then run against internal systems without a cloud model.
What sets LocalAI apart
- CPU-first design: GPU acceleration is optional, which suits older servers and edge devices.
- One server covers text, image, video and voice models with APIs modeled on several cloud vendors.
Where LocalAI is strongest
Available internationally
Open-source software with no country restriction that runs on your own hardware anywhere.
Questions to ask before you buy LocalAI
LocalAI is maintained by a small team together with the community, not by a company with a support contract, so plan internal ownership for updates and security patches. Voice cloning features need clear rules on consent. Check each model's license before use.
