Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for designers. The only one that takes vectors seriously.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
