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.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
