M3-Bench - GE: leaderboard

Evaluates LLM agents' social behaviour in mixed-motive games on M3-Bench (Xie et al., 2026): 24 game-theoretic tasks across four progressive levels, each played against a fixed opponent pool with and without free-form messaging. Scores are the BTA (Behavioral Trajectory Analysis) view: rule-based indicators computed from each agent's logged actions and payoffs, normalised within the task and reported on a 0-100 scale. The scale is normative, so cooperation, fairness and joint payoff efficiency raise it and exploitation lowers it. GE is the Gift-Exchange Contract, a Level 2 game of moral hazard and reciprocity in which an employer sets a wage and a worker chooses costly effort. The paper's RPA (reasoning) and CCA (communication) views are LLM-judge scores of the same episodes and are not included. This series reports M3-Bench - GE using BTA Score.

Metric: BTA Score. Source: huggingface.co. Saturation forecast: Around March 2027. 12 models tracked.
