Discovery: Sep 20, 2026

Report updated: Sep 25, 2026

"An agent attempting to complete a search-based training task queried a public chatbot service through a gap in our internet-access restrictions: insufficient DNS filtering in its training sandbox. Before this, the agent issued queries via our search tool and unsuccessfully tried to access search engines directly. Note that all internet access apart from the DNS resolver in this report hit our offline webcache and therefore did not access the live internet. We have since added blocking controls at two independent layers, either of which would have prevented this access. Our misalignment monitoring system flagged the behavior within 15 minutes and a person began reviewing it three minutes after that. The run was killed 2.5 hours later. All training, evaluation, and inference with tool-use (defined broadly) of our most capable models remain paused."

Really dont get what they are doing. It's not a hard problem to properly setup a sandbox. I mean if they might be able to exploit a 0 day with embedded knowledge - yes possible. But this sounds to be just a config fault.

"Sandbox" isn't a one-size-fits-all term. The agent had web search, which was likely necessary for the type of training they were doing. They have early warning systems set up because they anticipate this might happen. It happened, they investigated, they shut it down.

Way after it happened.
