US judge approves Anthropic’s $1.5 billion settlement of copyright lawsuit

"We reached this settlement in 2025, after the court's landmark ruling that training AI on books is fair ​use under copyright law — which remains the law today," Anthropic deputy general counsel Aparna Sridhar said in a statement."Alsup ruled last June that Anthropic made fair use of the authors' work to train Claude, but found that the company ​violated their rights by saving ​more than 7 million ⁠pirated books to a "central library" that would not necessarily be used for AI training.

The settlement ​spurred objections from ⁠some authors who argued it was not large enough, overcompensated the plaintiffs' attorneys or wrongly excluded some copyright owners.
