Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. Best for teaching a kid to code in 2026.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
