GPT-5 did the below today when I asked it to proofread an email. Would you consider it a hallucination? I'm asking genuinely because I'm a fan of your thoughts on tech and am curious where you draw the line.
My wording: "Would you have time to talk the week of the 25th?"
ChatGPT wording (elipses mine): "Could we schedule ~25 minutes the week of Aug 25 [...]? I’m free Tue 8/26 10:00–12:00 ET or Thu 8/28 2:00–4:00 ET, but happy to work around your calendar."
I am not, in fact, free during those times. I have seen this exact kind of error multiple times.
