Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.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.
