Artificial intelligence firm Anthropic has reached a settlement in a class action lawsuit filed by a group of United States authors who claimed the company’s AI training infringed their copyrights, according to a court filing on Tuesday.

The settlement marks the first resolution in a wave of high-profile AI copyright cases in the U.S.

In June, a California judge ruled that Anthropic may have downloaded up to 7 million books from pirate websites, potentially exposing the company to billions of dollars in damages if the authors’ claims had succeeded.

Anthropic did not provide details on the settlement terms, and a company spokesperson declined to comment on the filing.

“This historic settlement will benefit all class members,” the authors’ attorney Justin Nelson said in a statement. “We look forward to announcing details of the settlement in the coming weeks.”

U.S. District Judge, William Alsup, has set a September 5 deadline for the parties to seek preliminary approval of the settlement.

The case is among multiple lawsuits filed by authors, news organizations, and other copyright holders against AI companies such as OpenAI, Microsoft, and Meta Platforms over their training practices.
