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

  • Can't be used without Claude subscription
  • Not for full songs with vocals
  • Shorter generation limits
  • Less agentic than Cursor/Claude Code
  • Model quality varies
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.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
