Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for open-source model APIs.
