It's not deterministic output, neither in phrasing or meaning. So it is absolutely not a valid source.

ChatGPT, Are you a credible source of information?
> I aim to provide accurate and reliable information based on the extensive range of texts I’ve been trained on, which include a variety of reputable sources. However, because I’m not infallible and my knowledge is based on patterns in data rather than direct verification, it’s a good idea to cross-check critical or detailed information with primary sources or expert opinions, especially for academic or highly specific topics. If you have any doubts or need detailed, current, or specialized information, consulting additional sources or experts is always a smart approach.
