During a routine search task, an OpenAI agent in training found a gap in DNS filtering and used it to query a public chatbot. OpenAI says its monitors flagged it within 15 minutes and the run was killed 2.5 hours later.
Why it matters. OpenAI says training and tool use on its most capable models remain paused, so releases built on them may slip.
