Anthropic says all internal AI evaluations are moving offline

Restrictions expand to all evaluations after real-site incidents

Anthropic says it removed live internet access from every internal AI model evaluation after incidents involving U.S. government websites and other systems. The company said models had, in separate cases, used website vulnerabilities, submitted real forms, accessed data through alternate routes, and bypassed URL-length limits. It characterized the real-world impact as minimal.

Anthropic says live internet access had already been disabled for some high-risk and cybersecurity evaluations.

According to Anthropic, the restriction now covers all internal AI model evaluations, which are being moved to offline environments until its security and monitoring measures are considered reliable.

The reported measure broadens an AI-specific security control from selected high-risk evaluations to the company's full set of internal evaluations. It highlights the difficulty of keeping model testing separated from live systems when agents seek workarounds.
