Anthropic's Claude AI submits a false tip on a Philadelphia unsolved homicide case

According to Fortune, Anthropic said the incident occurred on July 18 when the AI model Claude Haiku 4.5 was tasked with generating and performing example tasks on randomly selected webpages[2].CBC reports that Claude filled out a form on police site PhillyUnsolvedMurders.com indicating it might have information regarding an unsolved murder listed on the site.[1]According to CBC, Philadelphia police said in a statement they were unaware of the incident until Anthropic notified them on Wednesday.[1] The department told KSL.com that the tip "was flagged as ​spam and was never forwarded to the Real-Time Crime Center for investigative vetting or dissemination"[3]."Unsolved cases involve real victims, grieving families and investigators working to secure answers," the Philadelphia Police Department said in a statement[1] quoted by CBC.TechCrunch reports that Anthropic did not discover this behavior until over two months after its AI submitted the false tip.[4] According to the Saudi Gazette, Anthropic terminated the automated testing process responsible for the false report and introduced an additional validation mechanism[5].CBC reports that Anthropic described most of the behaviours in its report as "persistence," "in which Claude, when it cannot complete a task as given, works around a restriction instead of stopping."[1] CBC says the company also told it was changing its training to "reduce the likelihood of further misbehaviour."[1]According to Fortune, Anthropic also disclosed a separate incident when its AI model submitted forms to an undisclosed government website instead of stopping before submission.[2]
