A federal judge has approved Anthropic's $1.5 billion copyright settlement over pirated books used to train its Claude chatbot, with authors and publishers set to receive about $3,000 per book. The case produced a mixed ruling for the AI industry: training on copyrighted books was found not to be illegal, but Anthropic's use of pirated copies from shadow libraries was. The Associated Press reports: District Judge Araceli Martinez-Olguin said in a Monday ruling that the class-action settlement provides "meaningful relief" to affected authors and publishers. About 91% of the more than 482,000 books covered by the ruling have been claimed by authors or publishers who are now due payment. Plaintiff attorney Justin Nelson said in a statement that the settlement was "the largest known copyright recovery in history. We look forward to making distributions to the Class as promptly as possible."Read more of this story at Slashdot.
