Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for solo + free. The best free option, hands down.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
