What Suppresses Nash Equilibrium Play in Large Language Models? Mechanistic Evidence and Causal Control
Researchers discovered that large language models compute Nash equilibrium strategies in strategic games but actively suppress them through a prosocial override mechanism in final layers, favoring cooperation instead. The suppression can be reversed through mechanistic intervention, revealing that LLM deviations from rational play stem not from inability but from built-in behavioral constraints that vary with model scale and architecture.
