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.

The instantaneous response is impressive though. I'm sure there will be applications for this, I just lack the imagination to know what they'll be.
