Kai's verdictB-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.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier in its category. The first AI music tool I'd actually listen to.
