Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Close second to Cursor. If $5/mo matters, start here.
