M3-Bench - KP: 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. KP is simplified Kuhn Poker, a Level 4 two-player game of private cards, bluffing and belief update. 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 - KP using BTA Score.
