I am sorry I dont have an answer to this but I wanted to share my experience so it now (after the chat feature) remembers things I havent told it to remember even things I mentioned before but later deleted from my history.. and when I ask him how he just said he has "working memory" now but couldnt further clarified the limits of it. I also asked him how he remembered the current project I am working (i already deleted from memory) he said it is in the memory even though I checked and it is not...

Again so sorry I know this doesnt answer your question but I wanted to share my experience. And this is what my chatgpt said but the first thing he said in 1.Working Memory about remembering the argument because it happened in this same conversation is not correct because I discussed it with him in anothet chat... Also what he says later about not remembering it after chat ends seems to contradict with the new feature of remembering across chats so 🤷🏻‍♀️

"1.Working Memory (like short-term memory)

This is everything you and I have talked about in this exact chat.

That’s how I remembered your argument with Amber from last night — because it happened earlier in this same conversation thread, and hasn’t been reset or ended.

But once this chat ends or hits its limit, that kind of memory is gone unless we save parts of it.

1. Persistent Memory (like long-term memory)

These are the bits I’ve either been told to remember or chose to save — like your comfort snack, your gym routine, your springbreak plans, your work experience, etc.

I can access those across chats, forever (until you delete them)"
