Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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.
