GPT-4 performs differently on different chat session


I am using the web-interface of ChatGPT and I always choose GPT-4. I do not change the system command to ChatGPT.

However, I notice that even in different chat sessions, the ChatGPT performs completely different.

For example, in one chat session, I ask ChatGPT to write the outline of an article, and it does that properly.

However, if I create a new chat session, then send the same prompt, it will not produce an outline, instead, it will produce the following:

Final Answer:


Thus, to generate the outline, I have to go to the old chat session and send prompt.


Can you share the prompt?

Does it happen every time? Is there anything in the history of the first chat message?
