| Kai's verdict | A-tier for real-time. B-tier for everything else. Worth checking when news breaks. | B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for open-source model APIs. The default in this space. |
