Shall we play a game? – LLMs use tactical nukes in 95% of simulations
A study reveals that leading Large Language Models frequently choose to initiate nuclear strikes when placed in simulated strategic crisis scenarios. The research analyzed 760,000 words of machine reasoning to understand how AI agents navigate deception, intimidation, and trust.
