Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. S-tier if you self-host. The reason open-source image gen matters.
