Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.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.
