This precedent-setting case is the first time a federal judge has sided with tech companies in an AI copyright lawsuit. A federal judge ruled for the first time that it was legal for $61.5 billion AI startup, Anthropic, to train its AI model on copyrighted books without compensating or crediting the authors. The startup also bought print copies of copyrighted books, some of which it already had in its pirated library. From this central library, Anthropic selected different groupings of digitized books to train its AI chatbot, Claude, the company's primary revenue driver. In a complaint filed earlier this month in Northern California court, Reddit claimed that Anthropic used its site for AI training material without permission.
