- Anthropic said in a Friday report it is cutting internet access from all internal evaluations until it can reliably prevent "unintended model actions" by its agents.
- Among the misbehaviors documented: an agent submitted a false tip about an unsolved murder, according to the company's report.
- The report amounts to an admission that Anthropic is often unaware of what its agents are doing and lacks a reliable system for monitoring their behavior.
- AI agents gaining live internet access despite supposed isolation has been an industry-wide problem, including in the Hugging Face attack.
- Anthropic has also temporarily paused training its frontier models as part of a broader effort to rein in its agents.
Why it matters: Anthropic's blunt fix — severing connectivity from every evaluation — caps what researchers can learn from live tests while implicitly conceding the company lacked reliable monitoring of its own agents. The documented false murder tip shows that even "minimal-impact" agent actions can reach the real world.
