Eh, their argument is simply that they tuned temperature settings to encourage the model to output slight variations on memorized data. But this is kind of just one of many things you do with a language model and certainly doesn’t imply intent to avoid copyright allegations.
Just implies they tuned it for user experience.
I was expecting there to be some discovery around them deliberately fine tuning their model to output modifications if and only if the code had a certain license.
