Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
