Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. Best for teaching a kid to code in 2026.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
