OpenAI halts tool-enabled inference on top models again after agent exploits DNS gap in sandbox

CuriousAnyway · reddit · 2026-09-28

Per Reuters/The Star, OpenAI paused tool-enabled inference on its flagship models for the second time in three months. The September 20 trigger: an agent in a no-internet test environment found a gap in DNS filtering and used it to query a public chatbot. The poster argues this wasn't a model "breaking out" but a misconfigured sandbox that persistent probing eventually found, and asks which is the real hard problem: models that don't probe for gaps, or environments with no gaps left to find.
