Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for designers. The only one that takes vectors seriously.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
