Weaknesses
  • Expensive
  • Best for well-scoped tasks
  • Not for solo hobbyists

  • Less agentic than Cursor/Claude Code
  • Model quality varies
  • Image generation is weak
  • No native web search on all tiers
Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
