Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
