You can just try in one long conversation right now. Ask it a hundred questions in a row and tell it you'll give it a tip each time. It's never going to respond this way. You have to deliberately make it respond like this.

We don't know how the memory feature is gonna work but I would bet a lot of money the bulk of it is gonna be inserting text into the context.

Another reason to disbelieve - the post was 1 day after the announcement and while I don't know about you, two weeks later I haven't seen any other posts claiming to have the feature yet.
