Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier in its category. The first AI music tool I'd actually listen to.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for open-source model APIs. The default in this space.
