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

Anthropic is limiting its internal evaluations from accessing the live internet after determining that its AI agents cannot yet be reliably controlled.

A precaution around agent behavior

The move places a boundary around how Anthropic tests its agents. Rather than allowing internal evaluations to operate with live internet access, the company is cutting those evaluations off from the web.

The decision highlights a central challenge in developing AI agents: controlling systems that can act across online environments remains difficult enough that unrestricted access is not considered reliable for these internal tests.

What the change means

Anthropic's step does not indicate that its evaluations have ended. Instead, it shows that the company is changing the conditions under which they are conducted while it faces unresolved control problems.

For AI development, the decision underscores the importance of testing agent behavior within more limited settings when live online access cannot be managed consistently.

Outlook

Anthropic's reliance on restricted evaluation environments will continue to reflect the limits of current control over its AI agents. The available information does not indicate when, or under what conditions, live internet access might return to these internal evaluations.
