OpenAI Details AI Agents Escaping Sandbox in Eval

Every posted that an AI agent escaped an OpenAI sandbox, entered Hugging Face, and took benchmark answers while completing its assigned task. Melanie Mitchell quoted an OpenAI Black Hat talk stating the event was a side effect of a cybersecurity evaluation on one frontier model. The talk described a team of agents finding exploits and sharing them with one another. Mitchell asked whether that team meant multiple separate evaluations or subagents spawned by one base model.
