Best forDevelopers experimenting across models. Apps that want fallback logic.Developers who want an agent, not autocomplete. Large refactors, tests, docs.Designers brainstorming first drafts.Developers using open-source models (Flux, SDXL, Whisper, etc).
Strengths
  • 300+ models from one endpoint
  • Automatic fallbacks between providers
  • No subscription — just pay what you use
  • Runs locally, edits your actual files
  • Strong on large codebases with 1M context
  • Great at multi-step tasks
  • Prompt-to-UI with real layouts
  • Exports to Figma
  • Faster than hand-designing from scratch
  • Tens of thousands of models (image, video, audio, LLMs)
  • One-line API for any model
  • Cog framework for custom model deploy
Weaknesses
  • Slight markup over direct API
  • Some provider features not exposed
  • Terminal-based — learning curve
  • Can't be used without Claude subscription
  • Output needs designer polish
  • Pricing unclear / changes often
  • Cold starts on less-popular models
  • Pricing gets real at scale
Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier for open-source model APIs. The default in this space.
