Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for open-source model APIs. The default in this space.
