Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for open-source model APIs. The default in this space.
