OpenAI says frontier training now runs without live internet access.
OpenAI said on October 23 that frontier model training now runs without live internet access. It says it tightened isolation and uses its own agents to test whether they can get past the controls. The policy follows a September 20 incident involving a misconfigured DNS resolver. That incident date is historical, not a new breach on Friday.

This applies to OpenAI's internal training and evaluation, not every released product. OpenAI says it cannot fully disconnect its infrastructure because experiments need external connections. It says it must block indirect network routes instead. Those are company assurances, not independent certification that every route is closed.
Look for independent tests of the current controls and results after configuration changes. TechCrunch also reported the new training policy.
