Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
