I was referring to producing a unique plot.

The process of generating a story involves recombining and rephrasing the LLM's training data in unique ways, it's not a copypaste job. They generate content by predicting and generating text based on patterns, an this implicates a degree of transformation and synthesis.

Where do you draw the line between plagiarism vs inspiration, whether it's a person or an LLM? How long and similar to something existing does a fragment of text have to be to cross the plagiarism line?
