Is it possible that it "remembers" that url from it's training and the content tied to it?

[Retr0id]

Assuming the earlier statements from ChatGPT were correct, the feature did not exist before the training data cutoff, so that's impossible.

I don't think they prefix each document with the URL in the training set, but there might be URLs in the clear text.
