Kai's verdictA-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
