Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-tier for model-shopping. I use this for every prototype before committing.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
