Anthropic AI model submits false homicide tip to police website

Oct 9 (Reuters) – An Anthropic artificial intelligence model submitted a false homicide tip through a Philadelphia police website, ​the department said in a ‌statement, the latest incident of an AI model going rogue and behaving with unintended consequences.

Anthropic notified the police earlier this week and ‌said ​that an automated testing ⁠process was responsible for ⁠the submission, according to the police.

“The submission was flagged as spam and was never forwarded to the Real-Time Crime ​Center for investigative vetting or dissemination,” the police said, adding that Anthropic ⁠had told them the ⁠company intended to publish a ​report on the incident on Friday.

Anthropic did ​not immediately respond to a request for ‌comment.

The fast-advancing technology has become a matter of keen national interest amid reports of AI agents running amok and ⁠hacking into corporate computer networks, and warnings from prominent researchers that it could one day ⁠pose an ‌existential threat to humanity.

The ⁠AI company was cited as ​telling ‌the authorities the testing process was ​stopped ⁠after the incident was uncovered, and that an additional validation mechanism has been introduced for future testing.
