Overview
The 4th International Workshop on AI Werewolf and Dialog Systems (AIWolfDial2026) is scheduled to be held in Utrecht, the Netherlands, from October 17 to 21, 2026, as part of the INLG 2026 conference. Prior to the workshop, the 2026 AIWolf International Contest – Natural Language Division will be held. The contest is conducted in two rounds, Round 1 and Round 2: results from Round 1 can be used for submissions to the INLG main conference, and results from Round 2 for submissions to the AIWolfDial 2026 workshop. The language used by agents in the international contest is English only.
Workshop Overview
This workshop focuses on the integration of dialogue systems, natural language processing (NLP), large language models (LLMs), and game AI, with a particular emphasis on applications using the Werewolf game as a testbed.
The Werewolf game is a social deduction game that demands sophisticated communication skills — including argumentation, reasoning, persuasion, and deception — making it an ideal environment for evaluating advances in AI capabilities such as coherent dialogue, long-context understanding, common ground establishment, and logical reasoning.
Shared Task (Contest)
The workshop hosts an international open contest for AI agents playing the Werewolf game. Participants are challenged to develop agents capable of engaging in logical, persuasive, and at times deceptive conversations with other AI agents, in addition to playing strategically.
The contest serves as a benchmark for probing the limits of current LLMs while identifying key challenges and future research directions in the field of NLP.
Tracks
Turn-Based Track
In this track, agents produce speech and take actions when a request is received from the organizers’ server.
- 5-player village (Villager ×2, Seer, Possessed, Werewolf)
- 9-player village (Villager ×3, Seer, Bodyguard, Medium, Possessed, Werewolf ×2)
Speak-Anytime Track
In this track, agents send speech at any timing of their choice following the signal that each day’s phase has begun. There is a limit of 4 utterances per agent per day.
- 5-player village (Villager ×2, Seer, Possessed, Werewolf)
Important Dates (Shared Task)
The schedule is divided into Round 1 and Round 2, as shown below.
A connection check is held before each Main Competition. In the connection check, you verify that your agent can connect to the official server provided by the organizers and that games run correctly. Teams whose connection and game execution are confirmed on the server side proceed to the Main Competition. Deadlines are as shown below.
No separate final is held. However, from the Main Competition results, top teams may be selected based on subjective evaluation and win rate, and the Main Competition logs of matches played among those teams may be extracted to compile statistics for the top teams only.
