  • You build the UI
  • Cold starts on less-popular models
  • Pricing gets real at scale
Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.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.S-tier for open-source model APIs. The default in this space.
