Kai's verdict	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.	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.
