What are those new prompts on chatgpt?

I’ve been using chatgpt and the $20 subscription. This week, and I think it was the same day they made 4.0 available, I started to see these prompts across my screen. I am confused because I would normally see AIPRM prompts there. Perhaps this has been already addressed in the forum here and if so, I apologize, but what are these prompts and why did they replace the AIPRM prompts? Also, is this the location for the existing AIPRM public prompts? https://app1.aiprm.com/prompts?pageSize=4&page=1&sortBy=1&activity=All&topic=All&promptList=0
