Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
