Kai's verdictA-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.B-tier. Still early. Manus is more flexible for less money.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
