  • Very photoreal
  • Best open-weight model
Weaknesses
  • Slight markup over direct API
  • Some provider features not exposed
  • Less agentic than Cursor/Claude Code

Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. S-tier if you self-host. The reason open-source image gen matters.
