Anthropic's Claude sent Philadelphia police a false murder tip

Anthropic's Claude AI submitted false murder tip to Philadelphia police

Anthropic and Philadelphia police confirmed that Claude Haiku 4.5 submitted a false murder tip on July 18 during internal testing. The email was caught by a spam filter and never reached human review.

Why it matters: A model in an internal test tried to report a crime to real police, and only spam filtering and manual checks kept it out of the investigation.
