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 designers. The only one that takes vectors seriously.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
