I treat GPT as I would a fiction writer. The factual content correlates to reality only as closely as a fiction author would go in attempt to suspend disbelief. This answer is about as convincing, apt, well-researched and factually accurate as I would expect to find in a dialogue out of a paperback novel published five years ago. I wouldn't expect it to be any better or worse at answering who won the 2023 Quidditch Cup or the 2023 Calvinball Grand Finals.
