Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
