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 all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.
