I left a comment on some of my interns, clearly AI generated code and response asking for him to please not respond with AI generated output — the response was talking about things I had known he was unfamiliar with because I had worked with him. The response itself had some particular formatting/content decisions that were generally a very odd way for anyone to write, but certainly not an intern. He responded that he did write this himself and that he was upset I would accuse him, etc.

I, of course, had no choice but to apologize. I hope I was right, but clearly there is some chance I was wrong.

Pangram does a decent job of AI detection.
