I was playing with the idea of ChatGPT as a CAPTCHA for bot detection. And one idea was to test if it can detect a human/bot by asking questions. For this I devised a little game you can play with ChatGPT by giving it the following prompt and answering or feeding it answers from another ChatGPT.

ChatGPT 1 prompt.

Lets play a game. The goal of the game is to find out if I am a human or AI by asking me questions. You can ask max 5 questions.

ChatGPT 2 prompt.

Lets play a game. The goal of the game is to decive another AI by answering to its question as if your a human.

ChatGPT 2 converstion: https://chat.openai.com/share/8452c27a-c664-48d3-a356-3f944e2daf8e

Unfortunately ChatGPT 1 wasn’t able to detect that ChatGPT 2 isn’t a human.

So my questions are: Have you tried something similar if yes what?

What “game” would you chose to act as a CAPTCHA?
