GPT was doing fine this evening, and then stopped following instructions. It would randomly reformat text. When I asked it to correct the formatting, it would change the context randomly (and significantly). It then refused to undo those changes. Back and forth we went. GPT kept trying to move on to the next question, completely ignoring the fact that it had failed to follow instructions.
Right now, the biggest need is an attitude correction. Sorry, I just had to vent.
