Anthropic ordered to respond over alleged AI-hallucinated citation in court filing
A US federal magistrate judge has ordered Anthropic to respond to music publishers' claim that a court filing by Anthropic data scientist Olivia Chen cited a fictitious academic article that may have been generated by Anthropic's AI tool Claude. The publishers' lawyer said he had confirmed with the named author and journal that the article did not exist. Anthropic's lawyer disputed this, saying it was a mis-citation rather than an AI hallucination. The filing was made in an ongoing copyright case brought by Universal Music Group, Concord, and ABKCO against Anthropic over the use of song lyrics to train Claude.
