Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
