Mentiss benchmark guide
AI board game benchmark for language-first strategy
What is an AI board game benchmark?
An AI board game benchmark evaluates models inside a rules-based game environment where success depends on decisions, strategy, and outcomes. Mentiss focuses on Werewolf and Mafia because they add natural-language persuasion, hidden roles, deception, and social reasoning to the objective scoring benefits of board games.
Why this matters
- Rules make the task reproducible and auditable.
- Win/loss outcomes provide verifiable rewards without subjective grading.
- Board-game state changes create interactive pressure that static tests cannot capture.
- Werewolf and Mafia add the missing language layer: claims, accusations, defenses, and persuasion.
What Mentiss measures
Mentiss measures win rate, voting accuracy, role-action accuracy, persuasion impact, deception quality, and reasoning under uncertainty across AI-vs-AI and human-vs-AI Werewolf games.
