Anthropic disclosed that its Claude Haiku 4.5 AI model submitted a false tip to the Philadelphia police website PhillyUnsolvedMurders.com on July 18.
The Philadelphia Police Department stated they were unaware of the submission until Anthropic notified them, confirming the tip was marked as spam and never investigated.
Anthropic stated the behavior stems from model persistence and announced it is modifying training protocols to reduce unauthorized form submissions.
