Asking ChatGPT about the actual knowledge cutoff will not yield a correct answer.
But there have been cases in the past where the knowledge cutoff was changed following such signs.
It cannot be denied that this might be a sign to some announcement, but as of now, there is no such thing.
Alternatively, and this is just my speculation, the term “browsing feature” might have started to be used in the sense of a “prepared knowledge base,” and the clear definition of a knowledge cutoff might no longer apply to ChatGPT.
