Yes, I get that. I tested GPT 4 with both 'she' and 'he', and in both cases it consistently said that the student was late, across several trials for each gender. Once it said it was an ambiguous statement, but it never seemed to be sexist like older or smaller LLMs.

My bad, I should have written [he/she].

That was covered by the "depending on the pronoun" part; your statement didn't make sense otherwise. The response was nonsense.
