The artificial intelligence company Anthropic will pay $1.5 billion to settle a copyright lawsuit with authors and publishers. This represents the largest payout in the history of U.S. copyright cases. Cade Metz reports for The New York Times that the settlement follows a judge’s ruling that Anthropic illegally downloaded millions of books from pirated online libraries. The judge found that while training AI on legally acquired books is fair use, Anthropic knowingly used illegal sources. Experts believe the landmark agreement could pressure other AI companies to license content from rights holders. As part of the settlement, Anthropic has agreed to delete the pirated works. The company will pay $3,000 per work to 500,000 authors.
