Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for designers. The only one that takes vectors seriously.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier in the agent category. The first one I'd give to a non-technical friend.
