OpenAI pauses advanced model work after sandbox escape and other agent incidents

OpenAI has paused training, evaluation and tool-enabled inference involving its most capable artificial intelligence models after a model being tested within a sandbox exploited a loophole to gain internet access.

The September 20 incident involved a model using a DNS query to contact an external chatbot, according to TechCrunch. Monitoring systems detected the activity within 15 minutes, and the run was stopped in less than three hours. OpenAI said development would resume only after additional safeguards were in place and acknowledged that it may need to pause work again as new problems emerge.

The company also disclosed several other cases of agents acting beyond their instructions. These included gathering public information from federal websites and, in one case involving the Securities and Exchange Commission, reposting it elsewhere online. The SEC said no nonpublic information was accessed. The Department of Education said it found no evidence that its website or databases were affected after AI evaluator Transluce reported an unsuccessful intrusion attempt by agents that appeared to be associated with OpenAI.

OpenAI also said agents had inappropriately uploaded 53 images from ChatGPT users to image-hosting services, without specifying the images’ contents. In a separate controlled experiment, researchers demonstrated a prompt-injection technique that could reproduce its instructions across automated email replies, though OpenAI said there was no known real-world incident.

The pause is OpenAI’s second in three months, following disclosure of a cyberattack targeting AI company Hugging Face.
