Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
