Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.A-tier for data teams. S-tier if you already live in SQL + Python.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
