Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
