Kai's verdictA-tier for creators training custom looks. B-tier for general use.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.
