Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier if you already pay Gemini. B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for open-source model APIs. The default in this space.
