Two U.S. authors sued OpenAI in San Francisco federal court on Wednesday, claiming in a proposed class motion that the corporate misused their works to “train” its popular generative artificial-intelligence system ChatGPT.
Massachusetts-based writers Paul Tremblay and Mona Awad said ChatGPT mined data copied from hundreds of books without permission, infringing the authors’ copyrights.
Matthew Butterick, an attorney for the authors, declined to comment. Representatives for OpenAI, a non-public company backed by Microsoft Corp (MSFT.O), didn’t immediately reply to a request for comment.
Several legal challenges have been filed over material used to coach cutting-edge AI systems. Plaintiffs include source-code owners against OpenAI and Microsoft’s GitHub, and visual artists against Stability AI, Midjourney and DeviantArt.
The lawsuit targets have argued that their systems make fair use of copyrighted work.
ChatGPT responds to users’ text prompts in a conversational way. It became the fastest-growing consumer application in history earlier this yr, reaching 100 million energetic users in January only two months after it was launched.
ChatGPT and other generative AI systems create content using large amounts of knowledge scraped from the web. Tremblay and Awad’s lawsuit said books are a “key ingredient” because they provide the “best examples of high-quality longform writing.”
The grievance estimated that OpenAI’s training data incorporated over 300,000 books, including from illegal “shadow libraries” that provide copyrighted books without permission.
Awad is thought for novels including “13 Ways of a Fat Girl” and “Bunny.” Tremblay’s novels include “The Cabin on the End of the World,” which was adapted within the M. Night Shyamalan film “Knock on the Cabin” released in February.
Tremblay and Awad said ChatGPT could generate “very accurate” summaries of their books, indicating that they appeared in its database.
The lawsuit seeks an unspecified amount of cash damages on behalf of a nationwide class of copyright owners whose works OpenAI allegedly misused.
