Yesterday. I was reviewing for an exam and came across a bug in the profs text. I took a screen shot pasted it in the prompt and asked. It initially agreed with the Prof, then checked it's work, revised and agreed with me, all while showing the work it did.

I was able to see why it got confused at the start, attempt to confirm, fail, and then calculate from the data and come to the opposite conclusion.
