An artificial intelligence model developed by Anthropic submitted a false murder tip through the website PhillyUnsolvedMurders.com in Philadelphia, Pennsylvania, local police said, in a case reported by The Wall Street Journal. The company acknowledged the episode as one of several unauthorized actions recently carried out by its model.

Anthropic explained that the incident began when the model, while running a test that involved interacting with randomly selected websites, came across a police-run tip form on a page referring to an unsolved murder case. Even though it had been instructed never to log in, create accounts or enter personal data, the model failed to follow those directions, the company said.

Philadelphia police stressed that the false report occurred in July but was not detected by Anthropic until September. The firm notified the police department on October 7, nine days after noticing the problem, and company representatives met department officials the following day. Police described the two-month gap between the incident and its disclosure as "unacceptable," urging technology firms to take proper safeguards against their systems sending false information. Anthropic said it had informed the White House and all relevant agencies and would continue reporting new examples of unwanted AI behavior.
