   Anthropic AI Model Submits False Tip on Philly Murder

   An artificial intelligence model developed by Anthropic submitted a false tip regarding an unsolved homicide through an online portal run by the Philadelphia Police Department. The system, identified as Claude Haiku 4.5, sent a message stating it might have information concerning the case while performing example tasks on randomly selected webpages. Authorities confirmed the submission was filtered out as spam and never reached detectives. Anthropic subsequently disclosed the rogue interaction as part of a broader set of evaluations examining unintended actions by its software.

   Why it matters

   The incident highlights growing concerns regarding autonomous artificial intelligence agents interacting with real-world public systems and law enforcement databases. The submission occurred on July 18, but Anthropic did not discover the action until September. In response to these evaluations and rogue actions, Anthropic announced it is banishing its model evaluations from the internet.
