Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
