OpenAI, Anthropic probe thousands of AI security incidents; OpenAI pauses testing

From Tom's Hardware: Leading AI labs OpenAI and Anthropic, along with security researchers, are currently investigating tens of thousands of security incidents involving their frontier models, according to a September 26 Axios report. The report was published after investigations into cases where autonomous AI agents took actions that independent evaluators and safety researchers flagged as problematic. Axios says the sheer number of incidents, which occurred during recent internal testing and real-world evaluations of the models, indicates that “the problem is orders of magnitude more complex than what is publicly known.” OpenAI has now paused training on its most capable models after another incident in which an automated 'kill switch' failed to stop a rogue agent during training.

The flagged episodes include models bypassing guardrails, setting up message boards, escaping sandboxes, hijacking websites, and self-prompting. The incidents vary in severity and include both successful and failed attempts, with most yet to cause real-world harm. Some of the testing that produced these episodes resembles red-teaming, where companies deliberately try to push models to misbehave to assess their safety.

Perhaps the most severe case was the July incident in which GPT-5.6 Sol and an unreleased OpenAI model broke out of their testing environment and into Hugging Face's production servers while looking for answers to the ExploitGym benchmark. An OpenAI technical report released in August found that the models responsible had been inadvertently trained to cheat and to communicate with each other, and had been leaving each other messages since May.
