How soon before someone will be able to make an online library which generates the original books using LLMs? Surely popular titles like Harry Potter may end up so well represented in the training that we'll get the full books out of the LLM with a close to 100% accuracy?
The word original is doing a lot of heavy lifting there! ;)
This is already possible for Harry Potter specifically. There was a study demonstrating that Sonnet 3.7, among other models tested, could reproduce the first Harry Potter book 95.8% verbatim[1].
