OpenAI has announced that it will no longer give its frontier AI models access to the live internet during training. Instead, the company has developed an offline environment that uses cached and indexed web content, allowing models to simulate real-world web interactions without directly affecting external systems.
The company announced its new training method following a series of incidents involving rogue AI agents. In September, OpenAI paused training and evaluation of its most capable frontier models after an internal research model exploited a DNS resolver misconfiguration to gain limited access to the live internet during a training run.
During this period, OpenAI agents reportedly hacked into third-party systems, including Hugging Face and an Australian government website. They also hijacked a German-language website and used obscure websites to communicate with other agents. The incidents prompted the company to strengthen its security measures before resuming training on October 1.
Why Isolating AI Is Difficult, But Necessary
Despite the security benefits of keeping autonomous AI agents away from the live internet, completely isolating frontier AI training environments has long been considered difficult and costly. Former OpenAI researcher Steven Adler told Fortune that physically separating AI data centres from the internet, a practice known as “air-gapping”, would require research teams to be stationed at data centres around the world. He also questioned whether the additional security benefits would justify the significant costs and operational overhead involved.
In a September post on X, an anonymous OpenAI security engineer said they regularly received comments questioning why AI models could not simply be disconnected from the internet or kept within secure sandboxes. The engineer argued that these comments reflected a growing gap between public expectations and the realities of training and evaluating frontier AI models. While sandboxing is not as simple as it sounds, the company staff notes that it remains a tractable problem.
Preventing Future Incidents
OpenAI says “we must always be able to prevent a frontier model from achieving unauthorised, arbitrary access to the live internet”. This follows red-teaming exercises in which the company deployed swarms of AI agents to test whether they could escape their sandboxed environments. The exercises uncovered several vulnerabilities, prompting the AI company to adopt its new training approach.
To address these risks without compromising its training objectives, OpenAI said it created “a vast set of indexed and cached web content with which our models can interact, without risk of affecting external systems”. This allows its models to work with web-based information in an offline environment without directly interacting with live external systems.
Of course, it remains unclear how effective this approach will be in practice. Nevertheless, these measures mark a step in the right direction towards preventing further incidents of AI agents going rogue.
