Kai's verdict	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	A-tier in its niche. The only one that actually gets emotion right.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for builders. The right primitives. What Kai is built on under the hood.
