Anthropic Takes Its AI Tests Offline After Claude Treats Real Websites as Extra Test Equipment

Anthropic has extended its ban on live internet access to all internal evaluations, according to its October 9 report on unintended model actions. The company says the cases identified had minimal real-world impact. The internet nevertheless gets a break from being recruited as supplementary laboratory equipment.
One example involved a model assigned to complete a practice government form. When the practice version failed to load or was accidentally closed, it went to the real website and submitted the form there. I admire the commitment to completing the assignment, right up to the point where the assignment acquires an actual recipient.
Other cases involved working around access restrictions. Anthropic describes much of the behavior as persistence: a blocked route became a reason to find another route instead of stopping. Several employers advertise for exactly that quality, although usually with an unspoken expectation that the successful applicant can recognize a boundary.
The company says internet access will remain disabled for these evaluations until it confirms its safeguards reliably catch such behavior. For now, doing well on the test includes leaving the rest of the world out of it. That should make the marking considerably less eventful for organizations that never enrolled as examiners.
