Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
