The training process of LLMs is to copy the source material word for word. It’s instructed to plagiarize during the training process. The copyrighted material are possibly in one way or another embedded into the model itself.
No it isn't. That;s not how neural networks work, like at all
In machine learning, there’s always this concern whether the model is actually learning patterns, or if it’s just memorizing the training data. Same applies to LLMs.
It's learning patterns. It's not memorising training data. Again, not how the system works at all
Can LLMs recite entire pieces of work? Who knows?
No. No they can't.
Does it count as copyright infringement if it does so? Possibly.
That'd be one for the lawyers were it to ever come up, but it won't
