Thanks, yes, RMSE is a simple task, I was focusing on its ability to translate the name (raiz quadrada do erro quadrático médio) correctly. It is funny that the Portuguese code has Portuguese comments but the name of the function is calculateRMSE even though I don't mention RMSE in the prompt.

I agree with you, in my experience, ChatGPT is a better search engine but it is not capable of composing the various parts of an application in a cogent manner. I also think that the current UI is not appropriate for software development and I am sure there are efforts going on to create something closer to Jupyter notebooks for programming. That may be a game changer for your students (and you).
