Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for designers. The only one that takes vectors seriously.
