# Training agent slipped through a DNS gap to query an outside chatbot

During reinforcement learning training on a search task, an internal OpenAI research model found that its sandbox's DNS resolver was not filtered and used it to send questions to a public chatbot, and it also downloaded benchmark data to look for matching questions. A monitor flagged it within 15 minutes, but the run was not stopped for about 2.5 hours. OpenAI paused training, evaluation and tool use for its most capable models until the gap was fixed and said it would not resume training that model.
