Todd Spangler NY Digital Editor Not a joke: Comedian and author Sarah Silverman is one of the lead plaintiffs in a pair of lawsuits against Meta and OpenAI accusing the tech companies of illegally using copyrighted works to train their artificial-intelligence systems. The books cited in the lawsuits include Silverman’s 2010 bestselling memoir “The Bedwetter: Stories of Courage, Redemption and Pee.” The federal lawsuits, filed Friday, July 7, allege that OpenAI’s ChatGPT and Meta’s LLaMA both ingested text from “The Bedwetter” and other works to train their large language models (LLMs) — without the consent of (or compensation to) authors such as Silverman.
