Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
