Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. The Deep Research feature is genuinely useful.
