Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier inside Photoshop (Generative Fill). B-tier standalone.
