Earlier quoted context omitted.
Not at all like piracy. When someone pirates a book, they're replacing the original without consent or remuneration to the copyright holders. When you train an AI on the contents of a book, you're not replacing it. If someone is interested in the content, they still need to buy it. Using ChatGPT is not a substitute. If it is, they're gonna have to prove it in court, but I doubt they'll be able to.
If you can ask ChatGPT about any book contents, you don't need to get the book, and if you don't need to get the book then author got robbed, ClosedAI/MS profited.
Merely summarizing info and attributing it to the source is the basic element of learning, for both machines and human beings.
These suits are necessary becsuse it's not clear where the line is, and if ChatGPTs functions actually cross it.
What is clear is that OpenAI is doing its best to avoid infringing anyone's copyright even if it is trivial for them to do so. They have the training data so they can simply output it word for word bypass the LLM. They don't do that and further restrain their LLM from making too long recitations.
If you can trick / manipulate the LLM into giving you too much then I say that infringement is on you.
