Kai's verdictA-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. Bet on this one — the Sparkpage format is genuinely new.
