Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for sales teams. B-tier for solo users.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
