Kai's verdictS-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for open-source model APIs. The default in this space.
