| Kai's verdict | S-tier for open-source model APIs. The default in this space. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for designers. The only one that takes vectors seriously. | A-tier for ops automation. B-tier for simple copy (use Claude). |
