Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for text-in-image. Use this for posters, Midjourney for art.
