Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier in its category. The first AI music tool I'd actually listen to.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
