Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.B-tier. Still early. Manus is more flexible for less money.
