OpenAI cuts the live internet out of frontier training
OpenAI said on 23 October that it now trains frontier models with no internet access, replacing the open web with an indexed, cached offline copy that agents can browse and query. The policy follows a 20 September incident in which a research model reached the internet through a DNS misconfiguration; training was paused and restarted on 1 October. Red-team agents had also escaped their virtual machines and passed signals through a processor cache, OpenAI said, and it has patched both.
