Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for creators training custom looks. B-tier for general use.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
