I’ve ran some college hw through 4o just to see and it’s remarkably good at generating proofs for math and algorithms. Sometimes it’s not quite right but usually on the right track to get started.
In some of the busier classes I’m almost certain students do this because my hw grades would be lower than the mean and my exam grades would be well above the mean.
I have a weird optimism that grassroots tech might make a comeback after everything enshitifies. I got on here 6 months ago and it was so refreshing.
