I have been able to convince ChatGPT to give me large chunks of novels that are in the public domain , such as those on Project Gutenberg, including Pride and Prejudice. There are lots of conversations about whether or not LLMs (and machine learning, more generally) are forms of compression or not. Let me explain.
