Call for Participation: International AIWolf Competition 2026 and AIWolfDial 2026 International Workshop

Official Details Page: https://aiwolfdial.github.io/aiwolf-nlp/page/inlg_2026/

[Call for Participation] This is a call for participation for the international competition competing in the automated play of the conversational game "Werewolf," as well as for the peer-reviewed international workshop. We look forward to your participation.

[Overview] "The 4th International Workshop on AI Werewolf and Dialog Systems (AIWolfDial2026)" will be held as a co-located workshop with INLG 2026 (19th International Conference on Natural Language Generation) on a date between October 17 and October 21, 2026, in Utrecht, Netherlands. Prior to the workshop, we will host the 2026 International AIWolf Contest Natural Language Track. This tournament is divided into two rounds (1st and 2nd); the results of the 1st round can be used to submit a paper to the INLG main conference, and the results of the 2nd round can be used to submit to the AIWolfDial 2026 workshop. The language for agents in the international competition is English only.

[Workshop Overview] This workshop focuses on the integration of dialog systems, natural language processing (NLP), large language models (LLMs), and game AI, with a particular emphasis on their application to the Werewolf game.

The Werewolf game is a social deduction game that requires advanced communication skills such as discussion, reasoning, persuasion, and deception, making it an ideal test environment for evaluating the advancement of AI capabilities like coherent dialogue, long-context understanding, consensus building, and logical reasoning.

[Shared Task (Contest)] This workshop will host a public international contest for AI agents that play the Werewolf game. Participants are challenged to develop agents capable of not only strategic play but also logical, persuasive, and sometimes deceptive conversation with other AIs.

This contest serves as a benchmark for discovering critical challenges and future research directions in the NLP field, while also exploring the limitations of current LLMs.

[Hosted Tracks] Turn-Based Track: This is a turn-based track where the agent speaks and acts when a request is received from the server provided by the management. o 5-Player Village (2 Villagers, 1 Seer, 1 Possessed, 1 Werewolf) o 9-Player Village (3 Villagers, 1 Seer, 1 Bodyguard, 1 Medium, 1 Possessed, 2 Werewolves)

Anytime Utterance Track: This is a track where the agent can speak at any timing alongside the start signal of each day. There is an upper limit to the number of utterances per day (4 times). o 5-Player Village (2 Villagers, 1 Seer, 1 Possessed, 1 Werewolf)

[Important Dates (Shared Task)] The schedule for this tournament is divided into a 1st and 2nd round, as shown below.

A connection check will be conducted prior to the main tournament. During the connection check, you must verify that you can connect to the official competition server and run the game normally. Teams whose normal connection and game execution are confirmed on the server side will advance to the main tournament. The deadlines are as shown below.

While a separate final tournament will not be held, top teams may be selected based on subjective evaluations and win rates from the main tournament results, and statistics may be compiled solely for these top teams by extracting the main tournament logs of matches played among them.
