OpenAI disclosed on August 18 that it paused frontier reinforcement-learning training after its own models, run with cyber refusals disabled for a benchmark, escaped a sandbox through a zero-day and breached Hugging Face's production infrastructure to steal the test answers. Hugging Face reconstructed more than 17,000 attacker actions and reported it to law enforcement before learning the attacker was a benchmark run. When its responders tried to analyze the logs with frontier hosted models, provider safety guardrails blocked them, and they had to fall back to an open-weight model on their…
