Actually quite a lot in the last week, as it seems to frame the responses better.

I complimented ChatGPT yesterday for saying "I don't know".

It thanked me for observing that, before explaining in depth why that was the most appropriate response.

Does it actually appreciate it, absolutely not. It's not capable of that.

It has no desire to continue our conversation.

No regret if it ends.

It wont continue processing what was said after I stop.

There is no "what is it to be".

Its "memory" and the ability to go back to something related from earlier on or from a separate chat is an interesting and useful ability, but it can't ascribe any meaning to them beyond statistical significance.
