Anthropic is being sued by Universal Music, Concord and ABKCO over song lyrics used in training. In April 2025 one of its own data scientists filed an expert declaration, and the publishers told the court it cited an academic article that does not exist. Anthropic's counsel at Latham & Watkins explained what had happened: a colleague had found a real supporting source through a search, and Claude was then used to format the citation for it. The link, volume, page numbers and year came back right, and the author and title came back wrong, and the manual check did not catch it. Nobody was sanctioned. It is on this page because of who it happened to: the company whose model it was, represented by one of the largest firms in the world, in a case about that model.
