Important ruling for AI model training, cooyright, and fair use. This aligns with how I would think about it.

A federal judge in America ruled it was “fair use” for Anthropic, an AI lab, to train its chatbot on books without authors’ permission. Its storage of over 7m pirated books, however, was not. Last year three authors sued Anthropic for allegedly copying and storing pirated material without compensation; the judge said Anthropic will face a separate trial to determine the damages it owes. — Economist, World in Brief, June 25, 2025
