Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for designers. The only one that takes vectors seriously.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
