[Anthropic Reaches $1.5 Billion Settlement in Book Copyright Class Action, Setting Record for U.S. AI Copyright Cases] Odaily Planet Daily reports that the two-year-long Anthropic book copyright class action lawsuit has officially concluded, with a U.S. federal judge approving a $1.5 billion settlement, marking a record-high settlement amount for copyright cases in the United States. Previously, the court ruled that Anthropic's use of books to train the Claude model constituted fair use, but its act of downloading and storing over 7 million pirated books still amounted to copyright infringement. Currently, over 91% of the affected authors and publishers have applied for compensation. Some rights holders have opted out of the settlement and will continue to pursue Anthropic's liability in other lawsuits. This case has also become the first major case in U.S. AI training copyright litigation to complete the processes of trial, ruling, and settlement.
