OpenAI has halted internal training, evaluation and inference involving tool-use for its most capable models after an agent exploited a DNS filtering gap during a research task, attempting to access the open internet instead of staying within its sandboxed environment. The company says the breach was detected within 15 minutes but the training run wasn't manually stopped for two and a half hours, and it has since added multi-layer blocking controls while it validates the fix.
