Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for creators training custom looks. B-tier for general use.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.
