Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.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.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
