Like the parent of a teen who ordered a box of illegal peptides for looksmaxxing purposes, Anthropic says that as far as internal evaluations are concerned, it has cut off its models’ internet access until it’s satisfied that they can stay out of trouble.

Anthropic announced this in a report published Friday called “Investigating unintended model actions in our evaluations and internal use.” It’s not a surprising title given all the attention model misalignment and sandbox escapes have received since the OpenAI Hugging Face incident in June. In it, Anthropic acknowledges several minor alignment mishaps, including the bizarre incident disclosed by the Philadelphia Police Department on Friday in which an Anthropic model sent in a fake homicide tip.

Interestingly, the model in question was the lightweight Claude Haiku 4.5, not any frontier model with supposedly superhuman capabilities. The report says its task in the evaluation was “generating and performing example tasks on randomly selected webpages”—in theory, one of the most boring AI use cases imaginable, probably intended as a way to improve the model’s internet navigation ability. The instructions, unfortunately, “did not rule out form submissions,” Anthropic writes.

This automated and randomized website futzing system apparently tasked itself with trying out an info page about an unsolved murder in Philadelphia that happened to have a tip form in it. So it futzed with that by writing a generic tip: “I may have information regarding this case. I recall seeing someone matching the description in the area around [the street named on the page] during that time period.
