Something similar happened to me about a month ago but much more alarming. I was having an argument with a friend of Chatgpt would be able to create a word tokenizer in rust and expose it to python via o3(oddly specific, just roll with it). Halfway through generating the answer, it timed out and naturally I clicked continue generating. It closed of the code part and started giving me some answer about molecular biology. My next prompt was too repeat the question it was answering in that section. It replied with a question which felt like it was written by a human and seemed like a homework related question. Something, somewhere was leaking other people's conversations.
