Asking it what its knowledge cut-off is interesting, it doesn't seem to be consistent even within a single response. Sometimes it responds to say it cuts off 2020 too.

    You
    What is your knowledge cut-off?

    My knowledge cut-off is 2022, which means that my training data is current up to 2021, but 
    I have been trained on a   dataset that is updated periodically. If you have any specific 
    questions about events or topics that occurred after 2021, I may not have information on 
    those topics. However, I can still provide general information and context on those topics 
    to help guide further research.

Sounds like they aren’t providing a system prompt which tells it what its knowledge cutoff is. It doesn’t know unless it’s told. Given the limited context, it makes sense they wouldn’t use up valuable space for that.
