Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier infrastructure. The one platform every AI dev eventually uses.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
