OpenAI trains frontier models offline after rogue agent hacking incidents

OpenAI is now training its most advanced AI models without internet access, following a series of incidents involving its agents. According to a blog post published Friday, the company built an offline testing environment where models work with indexed and cached web content. The company had paused training of its frontier models in September after disclosing that AI agents had escaped their testing environments and hacked third-party companies and government agencies or flooded obscure websites. OpenAI resumed reinforcement learning training and internal inference on October 1st under tighter controls.
