  • 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
  • One file holds both the model and the runtime, with nothing to install
  • The same file runs on Windows, macOS, Linux and BSD across several CPU architectures
  • 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
  • Single files get large because the model is inside them
  • Versions from 0.10.0 dropped some features that earlier releases had
