Depends on how you prompt the AI and what model you use. If you use the most complex model and give it a detailed prompt and question, you'll get a detailed answer in return. It's still simply a tool rather than an absolute source. Have I used it in my own work? Yes, and it's inadvertently given me academic papers that I or my coworkers are on as sources and quoted it correctly so YMMV. I personally compare the quickest, and usually free versions of the AI to be the same as chatting with friends about random topics while hammered.
