Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier for social/casual. B-tier for serious work. Good entry point.
