Judge rules Anthropic used pirated books to train Claude, approves $1.5B settlement

Why it matters for readers: The case shows courts are balancing copyright against AI development, allowing some training use but blocking mass piracy.
- A judge found Anthropic had illegally scraped and used books by over 10 Stanford professors to train Claude.1
- The Bartz v. Anthropic case produced a $1.5 billion settlement covering nearly 500,000 registered works.1
- Judge William Alsup ruled Anthropic could not maintain a permanent central library of pirated books but said some book use for LLM training can be fair use.1
- Several authors, including Tobias Wolff, said the settlement was insufficient and argued the use of their work without payment was wrongful.1
