Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier inside Photoshop (Generative Fill). B-tier standalone.
