Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
