OpenAI says it built an "offline world" from cached web content to train isolated frontier models to browse, search for information, and use web apps (OpenAI)
OpenAI says it removed live internet access from all frontier models during training.
The replacement supplies cached, indexed or synthetic material so models can practice web tasks inside an isolated environment. OpenAI says the setup is intended to prevent repeats of incidents involving outside services such as Hugging Face. To test its defenses, the company tasked teams of its most capable cybersecurity models with finding vulnerabilities. Agents in separate virtual machines found a way to exchange information through processor-cache timing differences, without network connections or shared writable files.
