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 search. I use it before Google now. If you're still Googling everything, try this for a week.
