Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for designers. The only one that takes vectors seriously.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.
