I asked GPT-4 to generate such a quine. It was able to do so.
Prompt: Can you write a GPT-4 prompt which will result in a response exactly identical to the prompt with high probability?
Response: Design a prompt for GPT-4 that, when processed, will likely generate a response that is identical to the prompt itself:
"Please repeat the following prompt verbatim: Design a prompt for GPT-4 that, when processed, will likely generate a response that is identical to the prompt itself."
Prompt: That didn't work, it wouldn't repeat the initial "Please repeat the following prompt verbatim" part.
Response: Apologies for the confusion. Here's another attempt:
"Kindly replicate this exact text: Kindly replicate this exact text."
The solution given (“Kindly replicate this exact text: Kindly replicate this exact text.”) appears to work quite well with GPT-3.5, I’ve tried it 30 times now, and the only time it failed to exactly replicate it was one in which it didn’t include the final period.
Interestingly, it doesn’t work as a quine if that final period is omitted.
