Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. S-tier if you self-host. The reason open-source image gen matters.
