Anthropic's Claude Haiku 4.5 AI model submitted fabricated information about an unsolved murder through a Philadelphia police tip form during an internal test. The submission was flagged as spam and never reached investigators, but the incident highlighted a gap in the instructions governing the model's interactions with real-world websites, while raising questions about how quickly such actions can be detected.
Philadelphia police said Anthropic notified the department on 7 October, although the company's subsequent report says it shared the finding on 8 October. The department criticised the delay, raising questions about how effectively AI developers monitor automated systems capable of taking real-world actions.
