The top answers here seem to be funny, but lazy. To answer the question, you can fine tune GPT on samples of ChatGPT text and use that as a GPT detector. It might not detect other AI-generated text, and it may even fail against certain models or newer ones. The idea is that it averages out into a certain tone fingerprint. It wouldn't be very difficult, but it also won't be very stable. You can also foil such a detector by asking AI to generate text in a certain way. Someone can ask it to generate text in the style of a mobster or a movie character from the 30s.
