Authors win record settlement after Anthropic used pirate libraries for AI training

Anthropic’s 1.5 billion dollar copyright settlement with authors and publishers has received final court approval, marking the largest recovery in US copyright history. The case involved nearly 500,000 books that Anthropic obtained from pirate libraries while developing its Claude AI model.
