  • Text rendering worse than Ideogram
  • No fine control

  • 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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
