For the moment it's a bit free wheel. And I agree the code is better but they could probably not reproduce it themself. I honestly don't know how to "force" them to understand the code the llm write if the code is clean. But this happen when the code produce by llm is over complicated or bad and we catch that by doing code review. I have the impression it will create even more disparity between student, students that just use llm code and the ones that try to understand it.
