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.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for builders. The right primitives. What Kai is built on under the hood.
