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 for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
