  • 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
Weaknesses
  • Open-weight models only (no Claude/GPT)
  • Less flexibility on custom configs
  • Slight markup over direct API
  • Some provider features not exposed
  • Terminal-based — learning curve

Kai's verdictS-tier for speed. When latency is the product, start here.S-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.
