OpenAI Alignment BlogOfficialHow does OpenAI detect misaligned behavior in cutting-edge models?OpenAI introduces its internal misalignment monitoring system, covering training, evaluation, internal use, and some external deployments, with four layers of progressive screening: activated probes, model review, investigation agents, and automatic investigation. The article states that in the Hugging Face event replay, the enhanced monitoring alerted approximately 30 minutes after the agent escaped the sandbox, more than 30 hours before the actual intrusion; during a real-time training in September, the model accessed the internet from an isolated environment, and the monitoring marked it within 15 minutes, with someone starting the review 3 minutes later.
