OpenAI said on Friday it had resumed training of its most advanced AI models after tightening security and barring internet access, and disclosed a flaw in a widely used software that it found while testing its defenses. The disclosure comes amid concerns over the ability of increasingly capable AI agents to identify and exploit software flaws, including in the guardrails meant to contain them. OpenAI had paused training of its most capable models after one of its research models used a configuration error to gain limited internet access in September. The company said it contained the incident and used the pause to strengthen its defenses.
To test them, OpenAI had teams of AI agents try to break out of their restricted environments. It said the agents found previously unknown flaws, which it had fixed, and training resumed on October 1.
