Ashley Belanger, writing for Ars Technica, has the story of popular authors joining together to sue OpenAI, alleging the company trained its large language models by pirating their books.

Yesterday, popular authors including John Grisham, Jonathan Franzen, George R.R. Martin, Jodi Picoult, and George Saunders joined the Authors Guild in suing OpenAI, alleging that training the company’s large language models (LLMs) used to power AI tools like ChatGPT on pirated versions of their books violates copyright laws and is “systematic theft on a mass scale.”

“Generative AI is a vast new field for Silicon Valley’s longstanding exploitation of content providers," Franzen said in a statement provided to Ars. “Authors should have the right to decide when their works are used to ‘train’ AI. If they choose to opt in, they should be appropriately compensated.”

OpenAI has previously argued against two lawsuits filed earlier this year by authors making similar claims that authors suing “misconceive the scope of copyright, failing to take into account the limitations and exceptions (including fair use) that properly leave room for innovations like the large language models now at the forefront of artificial intelligence.”

This latest complaint argued that OpenAI’s “LLMs endanger fiction writers’ ability to make a living, in that the LLMs allow anyone to generate—automatically and freely (or very cheaply)—texts that they would otherwise pay writers to create.”

I bet OpenAI uses ChatGPT to answer the suit.
