Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for ops automation. B-tier for simple copy (use Claude).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.
