This doesn’t mean it can’t remember. A lot of times it outputs this for stuff that it actually can do if you prompt it correctly, which can take some experimenting to figure out.

From my experience it remembers previous responses and Can talk about them. One time I asked it about a particular fact, it gave a slightly wrong answer, I said this was wrong and provided the correct answer, and it said my response was correct. I asked it if it was incorrect initially and it said that it was, and provided more context for the answer as well.
