Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for designers. The only one that takes vectors seriously.S-tier for open-source model APIs. The default in this space.
