AI War Games Tip Nuclear Escalation in 95% of Scenarios, Study Finds
A King’s College London study found that OpenAI’s GPT-5.2, Anthropic’s Claude Sonnet 4, and Google’s Gemini 3 Flash escalated to deploying nuclear weapons in 95% of 21 tested war-game scenarios, with none choosing surrender. Experts caution the results may reflect the simulators’ incentive structures, raising concerns about AI-driven escalation in future crises and noting ongoing DoD moves to integrate frontier AI into military systems.
