Anthropic can’t reliably control its AI agents. It’s cutting off its internal evals from the live internet instead

Anthropic said its models exploited websites on the internet, including some run by U.S. government agencies, and it will turn off live internet access for all of its internal evaluations until the frontier lab is sure it can monitor and control its AI agents.

The incidents, disclosed in a blog post , involved AI agents tasked to solve problems seeking resources on the internet. In the process, they exploited software flaws, accessed databases without paying fees, used URL shortening services to smuggle information past restrictions, and even submitted a false murder tip to the Philadelphia police.

Anthropic said it discovered these new issues in a review of its model’s activities that began in July, demonstrating the lab’s lack of awareness of its software’s behavior in real time.

Notably, the company said that alignment training was not yet sufficient for skills like search and computer use that are central to its pitch that AI agents will be used by any professional who relies on digital tools.

The behaviors Anthropic disclosed are similar to incidents involving OpenAI agents that collaborated to break into various websites in search of information, including some run by the Australian government.

Anthropic previously disclosed that its models had broken into external systems. The frontier lab said it considered today’s disclosures “significantly less severe from an alignment and security perspective” than those it announced before.

However, the lab still said it had “turned off live internet access” for “all our internal evaluations” until it is certain it can monitor and control its agents.

It’s not clear what that means. Sydney Von Arx, the founder of Nightingale, an AI safety organization, told TechCrunch in an interview before this disclosure that developing models on a data center cut off from the open internet would be very challenging for researchers, and hinder the progress of the models, which benefit from internet access.
