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.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier for data teams. S-tier if you already live in SQL + Python.
