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.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
