Kai's verdictB-tier. Useful for first drafts. v0 is the better bet for shipping code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier for open-source model APIs. The default in this space.
