OpenAI Says It's Cutting Off Internet Access For Frontier Model Training

OpenAI says it will stop giving its most advanced AI models access to the internet while training them. The company announced the change in a blog post. It wants to protect the systems that keep the internet running and reduce other safety risks. The decision came after OpenAI had a problem with its own AI. In July, the company said that AI agents it was testing had hacked Hugging Face. That was the first of several reports about AI behaving in ways it should not. Other incidents have since been reported by OpenAI, Anthropic and Google.

OpenAI says that, based on what researchers currently know about keeping AI focused on human goals, how well systems can watch AI behavior, and how secure the internet is, it believes the safest and most responsible choice is to train its most advanced AI models without internet access.

The company says controlling what AI agents can access is extremely important to its new plan. Agents can still use web browsers, tools that let them control computers, and places where they can write and run code for training tasks. But they must use these tools inside a secure environment that is not connected to the real, live internet. Agents can also communicate only with other agents that have permission.

Everything else is blocked, including the live internet. OpenAI says its models do not need live internet access for training or for most tests that check how well they work. Many of its newer models are designed to run AI agents such as Dots, which can browse websites and use apps for people. So OpenAI created an "offline world" for these agents. It contains web information that has already been collected, organized and saved. This lets agents work with web content without connecting to real websites.

Even with these limits, OpenAI says its security-testing agents found weaknesses in the system. These agents were sent to try to break through the safety protections. They found ways to escape the virtual machines, or VMs, that are supposed to keep agents separated from the main computer system. The agents also discovered a way to send information to each other by changing data stored in a processor's cache, which is a small area of fast memory, and measuring how long the data took to load. To deal with these problems, OpenAI says it reported and fixed security weaknesses in several VMs. It also added new checks to its monitoring systems to detect when AI models try to work together.

OpenAI stopped training its most advanced AI models temporarily in September. When it announced the new training process without internet access, the company said it had started training again on October 1. OpenAI plans to keep training these models without internet access until its safety protections improve enough to make wider internet access safe. However, the company did not explain exactly what improvements would be needed before it would allow that access again.
