Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier for designer-led sites. S-tier if animations matter.
