I am replying to the parent comment, but I too get that this petition is being signed onto by people at openAI specifically because they already made it with GPT-4. They definitely would not sign on to it if their (arbitrary) threshold for what to stop doing AI research with was a tool at a GPT-3 or GPT-3.5 level or higher or it included GPT-4 in their threshold, and not merely beyond it.
