Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
