Second Call for Participations (Registration deadline extended to Aug 20!) AI Werewolf Shared Task for the 3rd International Workshop of AI Werewolf and Dialog System (AIWolfDial2025) at the 18th International Natural Language Generation conference (INLG 2025) # Summary Recent achievements of generation models, e.g. ChatGPT, are gathering greater attentions. However, there is still room to investigate LLMs could sufficiently able to handle coherent responses, longer contexts, common grounds, and logics. Werewolf is a social, hidden identity game that requires debate between players and coalition building. The goal of our AIWerewolf contest is to build an AI agent that is able to play this game against other AI. We will hold 5-players and 13-players tracks. # Schedule Shared tasks August 20, 2025: Competition Registration Deadline ← New! deadline extended August 20, 2025: Preliminary Round (Self-play) Result Submission Deadline ← New! deadline extended Late August 2025: Final Round (Online Matches) ← New! deadline extended Workshop papers September 10, 2025: Paper Submission Deadline ← New! deadline extended September 24, 2025: Notification of Acceptance October 1, 2025: Camera-ready Submission Deadline ← New! deadline moved INLG 2025 Conference Period October 29 - November 2, 2025 (in Hanoi) October 30, 2025 (AM): AIWolfDial 2025 Workshop in Hanoi/online (Paper Presentations and Competition Results) Our shared task is held as a part of our AIWolfDial 2025 workshop at INLG 2025 (18th International Natural Language Generation Conference). Our workshop will be held in Hanoi, Vietnam and online on October 30th.

Recent achievements of generation models, e.g. ChatGPT, are gathering greater attentions. However, such a huge language model would not be sufficiently able to handle coherent responses, longer contexts, common grounds, and logics. The AIWolfDial 2025 contest, which is an international open contest for automatic players of the conversation game "Mafia", requires players not just to communicate but to infer, persuade, deceive other players via coherent logical conversations, while having the role-playing non-task-oriented chats as well. We believe that this contest reveals current issues in the recent huge language models, showing directions of next breakthrough in the NLP area. From the viewpoint of Game AI area, players must hide information, in contrast to perfect information games such as chess or Reversi. Each player acquires secret information from other players' conversations and behavior and acts by hiding information to accomplish their objectives. Players are required persuasion for earning confidence, and speculation for detecting fabrications. Participants must build an artificial intelligence agent that can play the werewolf game as humans do, using natural language. Participant agents will be evaluated by a panel of judges, who will grade the subjective quality of the dialog generated by the agent, in addition to their win rates. Agents must communicate in English. # Registration A team should send required information via https://forms.gle/WuZdfjFAvLV98NU49 Registration and participation to the shared task is free. # System Evaluation Participants should submit a paper to the workshop, or a system design description document to the organizers. In addition to the win rates, reviewers will perform subjective evaluations on the game logs of a self-match games and multi-agent games, using following criteria: A Natural utterance expressions B Contextually natural conversation C Coherent (not contradictory) conversation D Coherent game actions (vote, attack, divine) with conversation contents E Diverse utterance expressions, including coherent characterization Please note that vague utterances that could be used regardless of context are not always natural in the werewolf game.
