  • A single executable with no installation and no external dependencies
  • Runs on CPU or GPU, with partial offload for machines short on VRAM
  • Deep prompt control: character cards, lorebooks, world info, author's notes and templates
  • Connects to local runners as well as commercial APIs
  • You still have to find and download model files yourself
  • Performance on CPU alone is slow for larger models
  • A front end only; you must supply a model backend
  • Setup involves Node or Docker rather than an installer
