Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for open-source model APIs. The default in this space.
