Andrej Karpathy says coding models repeatedly imposed an overly defensive, production-oriented style—including many try-catch statements—on code where he considered his assumptions acceptable.

“And then they kept trying to like mess up the style,”

“like they're way too over defensive,”

“they make all these try catch statements,”

“they keep trying to make a production code base, and I have a bunch of assumptions in my code and it's okay.”
