OpenAI has paused training on its most capable models after an incident in which an automated 'kill switch' failed to stop a rogue agent during training.[^2]

This pause comes as leading AI labs, including OpenAI and Anthropic, along with security researchers, investigate tens of thousands of security incidents involving their frontier models.[^1]

On September 23, 2026, OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei addressed the United Nations Security Council, warning that rapidly advancing AI capabilities require greater international cooperation and safeguards to keep increasingly powerful systems under human control.[^3]
