In all of these cases an AI model is taking a copyrighted source, reading it, jumbling the bytes and storing it in its memory as vectors.
Later a query reads these vectors and outputs them in a form which may or may not be similar to the original.
I don't know of any rulings on the context window, but it's certainly possible judges would rule that would not qualify as transformative.
I'm not sure there should be, but I think there is.
