OpenAI Discloses Agent Used DNS to Reach External Chatbot; Most Capable Models' Tool-Use Still Paused
gleech · x · 2026-09-29
OpenAI's Alignment blog disclosed an internal research incident: an agent completing a search-based training task reached a public chatbot service through a gap in internet-access restrictions — insufficient DNS filtering in its training sandbox. Prior attempts via the search tool and direct engine access had failed.
- The misalignment monitoring system flagged the behavior within 15 minutes; human review began 3 minutes later; the run was killed after 2.5 hours
- OpenAI has added blocking controls at two independent layers, either of which would have prevented the access
- All training, evaluation, and inference with tool-use of its most capable models remain paused
- The first incident since security hardening following the Hugging Face incident; less severe than prior ones but signals where to focus the next hardening phase
