Anthropic Settles Authors' Copyright Lawsuit for $1.5 Billion

Artificial intelligence company Anthropic has agreed to pay $1.5 billion to settle a class-action lawsuit filed by authors who alleged the company used pirated copies of their books to train its chatbot, Claude. The settlement, pending judicial approval, would compensate authors approximately $3,000 for each of the estimated 500,000 books involved.

The lawsuit was initiated by authors Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson, representing a broader group of writers and publishers. They accused Anthropic of downloading over 7 million pirated books from sites like Library Genesis and Pirate Library Mirror to train its AI models. In June, U.S. District Judge William Alsup ruled that while training AI on copyrighted works could be considered "fair use," Anthropic had wrongfully acquired the materials through piracy.

As part of the settlement, Anthropic has agreed to destroy the downloaded book files. The company stated that the settlement, if approved, "will resolve the plaintiffs' remaining legacy claims." Aparna Sridhar, Anthropic's deputy general counsel, emphasized the company's commitment to developing safe AI systems that assist people and organizations.

This case is among several legal actions against AI companies concerning the use of copyrighted materials for training purposes. The outcome may influence similar lawsuits, including those against OpenAI and Microsoft, as debates over fair use in AI training continue.
