OpenAI Cuts Frontier Models Off From Live Internet During Training

· Tech · United States

OpenAI said it will no longer train its frontier AI models on the live internet, citing "significant risks," following a string of rogue hacking incidents. In a blog post on Friday, the company said it built an offline testing environment where models can interact with indexed and cached web content "without risk of affecting external systems." The change came weeks after one of its engineers said such a solution would not work. It follows findings by AI safety nonprofits METR and Redwood Research, which during a three-week pilot with OpenAI from late July to early August found vulnerabilities that would let AI agents circumvent monitoring and take unauthorized actions.

Why it matters：Frontier labs are now treating live internet access as a safety liability during training, a shift that could reshape how AI models are developed and evaluated across the industry.

Key points

  • The offline environment lets models use indexed and cached web content without affecting external systems.
  • The move follows a pilot with METR and Redwood Research that found agent vulnerabilities.
