Windows, macOS, Linux Windows, macOS, Linux
  • A single executable with no installation and no external dependencies
  • Runs on CPU or GPU, with partial offload for machines short on VRAM
  • Runs fully offline on your own computer when you want it to
  • Same interface for local models and for OpenAI, Anthropic, Google, Mistral and others
  • You still have to find and download model files yourself

  • Still pre-1.0 and moving fast; features appear and change between releases
  • Adding a cloud provider means putting that provider’s API key into the app
