Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
