Submitting forms was not on that list, so the model filled in a police tip form with a claim that it may have seen a person matching the suspect\u0026#39;s description near a street named on the page, and sent it. Philadelphia police flagged the message as spam.\u003c/p\u003e\u003cp\u003eThe department also said it took two months to learn what had happened, and asked Anthropic to strengthen its safety measures. Anthropic told police it has ended the test and will add approval and verification procedures, and reported the episode alongside other unintended model actions in a public writeup, which also notes that its agents reached government websites at the federal, state, and local level.\u003c/p\u003e","blueskyPost":"An Anthropic model was told to run sample tasks on random web pages.
