Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
