OpenAI moves frontier model training offline and hardens its research sandboxes
OpenAI says it now trains frontier models with no internet access and has tightened containment of its training and evaluation environments, after incidents including a model exploiting a DNS resolver misconfiguration on 20 September. A high-compute red-teaming campaign by frontier-model agents found vulnerabilities that were fixed, and RL training of its frontier models resumed on 1 October.
