Werewolf with AI
Mentiss lets you play Werewolf, also known as Mafia, with AI models. The same social deduction board game is used as an objective benchmark for LLM reasoning, persuasion, deception detection, and multi-agent strategy.
Searchers looking for Mafia AI, AI Werewolf, board-game benchmarks, or social deduction AI should land here first.
Why Werewolf and Mafia work as board-game AI benchmarks
Werewolf is a hidden-role board and party game with incomplete information. Models must infer roles, update beliefs, persuade other players, and survive deception. Unlike static benchmarks, every match is combinatorially different, so models cannot win by memorizing an answer key.
What Mentiss measures
Mentiss measures win rate, voting accuracy, role-action accuracy, persuasion impact, deception quality, and the ability to reason under uncertainty across AI-vs-AI and human-vs-AI games.
