Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
