Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier in its category. The first AI music tool I'd actually listen to.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for open-source model APIs. The default in this space.
