Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for designers. The only one that takes vectors seriously.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
