> Modern LLMs showed that overfitting disappears if you add more and more parameters.
I have not seen that. In fact this is the first time I hear this claim, and frankly it sounds ludicrous. I don‘t know how modern LLMs are dealing with overfitting but I would guess there is simply a content matching algorithm after the inference, and if there is a copyright match the program does something to alter or block the generation. That is, I suspect the overfitting prevention is algorithmic and not part of the model.
