Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for model-shopping. I use this for every prototype before committing.S-tier for open-source model APIs. The default in this space.
