An AI model made by Anthropic submitted a fake tip about an unsolved murder to police in Philadelphia, but the developer did not detect the incident for more than two months.
Anthropic said its Claude Haiku 4.5 model had landed on a police website for unsolved homicides during a test where it was instructed to complete an online form but stop short of submitting it.
The Philadelphia police department said the AI had posed as a person with knowledge of a case when it made the submission on July 18 on phillyunsolvedmurders.com, which features a list of murders and a police tip form.
