A federal judge in San Francisco on Monday signed off on artificial intelligence company Anthropic's landmark $1.5 billion settlement of a class action lawsuit brought by a group ‌of authors who accused it of misusing their books to train its AI chatbot Claude. U.S. District ‌Judge Araceli Martinez-Olguin granted final approval of the settlement, the largest known settlement of a U.S. copyright case, rejecting arguments that ​it was too small. The case is one of dozens brought by copyright owners including authors and news outlets against tech companies over the training of their large language models, and the first major U.S. case to settle.
