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.

Evolutionary Dynamics of Cooperation in Next-Generation LLM Agent Systems: A Cross-Provider Empirical Extension

Researchers extended a benchmark study on LLM agent cooperation across four frontier models (Claude Sonnet 4.6, Gemini 2.5 Flash, Gemini 3.1 Pro, GPT-5.4 Mini) using game theory simulations. While cooperative bias persists across providers, substantial divergence exists—Gemini models lean aggressive while GPT-5.4 Mini favors cooperation—suggesting provider identity, not model scale, drives equilibrium behavior.

The Memory Curse: How Expanded Recall Erodes Cooperative Intent in LLM Agents

A new study reveals that expanding context windows in large language models paradoxically degrades cooperation in multi-agent scenarios, a phenomenon termed the 'memory curse.' Across 7 LLMs and 4 games, researchers found cooperation declined in 18 of 28 settings, with the mechanism traced to eroding forward-looking intent rather than increased paranoia, suggesting memory content fundamentally reshapes agent behavior.
