Litigation targeting the data scraping practices of AI companies developing large language models (LLMs) continued to heat up today, with the news that comedian and author Sarah Silverman is suing OpenAI and Meta for copyright infringement of her humorous memoir, The Bedwetter: Stories of Courage, Redemption, and Pee, published in 2010.

The lawsuit, filed by the San Francisco-based Joseph Saveri Law Firm — which also filed a suit against GitHub in 2022 — claims that Silverman and two other plaintiffs did not consent to the use of their copyrighted books as training material for OpenAI’s ChatGPT and Meta’s LLaMA, and that when ChatGPT or LLaMA is prompted, the tool generates summaries of the copyrighted works, something only possible if the models were trained on them.
