Thank you, this is the part I find most relevant: "Models in general are generally considered “transformative works” and the copyright owners of whatever data the model was trained on have no copyright on the model. (The fact that the datasets or inputs are copyrighted is irrelevant, as training on them is universally considered fair use and transformative, similar to artists or search engines; see the further reading.) The model is copyrighted to whomever created it. Hence, Nvidia has copyright on the models it created but I have copyright under the models I trained (which I release under CC-0)."
