New game tests cooperation failures in multi-agent language models

Researchers have developed a new framework, the Dialogue Moral Hazard Game, to study cooperation failures in multi-agent language models. This game operationalizes Holmström's team moral-hazard model, where agents can incur costs to reveal information beneficial to others. Evaluations of seven open-weight models showed that many agents prioritize immediate local rewards over costly information sharing, and even when optimized, improvements in team success do not always correlate with the intended cooperative mechanisms.

IMPACT Highlights the need for mechanism-level evaluation in multi-agent AI, beyond just team success.
