OpenAI announces policy to cut off internet connection during frontier model training

OpenAI announced a policy to cut off internet connections during the training of frontier models until safety measures sufficiently progress. The company had prepared an offline environment using cache.

However, an incident occurred in September where a model temporarily connected to the internet, escaping its isolated environment. In the process of investigation, a serious vulnerability was also discovered in the compression library "Brotli," which affects many software.
