Open-source desktop AI that runs models locally on your own machine
Download and run open models such as Llama, Mistral, Qwen, Gemma, and DeepSeek directly on your own machine, with chat data kept on device.
Optionally connect API keys for OpenAI, Anthropic, Gemini, Mistral, and other providers to route requests to frontier models from the same interface.
Jan exposes a local server endpoint that follows the OpenAI API shape, so existing SDKs and tools can talk to your local models without code changes.
Create assistants with their own system instructions, model selection, and parameters, then reuse them across conversations.
Run and build with open AI models locally or in the cloud
Install once and pull open-weight models by name; Ollama handles weights, quantization and versioning for you.
A built-in server exposes a straightforward REST API, so scripts, editors and agents can talk to local models with minimal setup.
Route requests to hosted open models when your laptop cannot hold the checkpoint you need, with per-token pricing and concurrency tiers.
Access families such as Llama, Qwen, DeepSeek, Gemma, Mistral and gpt-oss from a single interface.
