Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
