Diplomacy and
Meta AI’s CICERO
Learn about the game, watch our AI agent CICERO play with experts and read about its performance in an online league.
About the game
Diplomacy* is a seven-player board game that can be described as a combination of the board game Risk, the card game poker, and the TV show Survivor. The game begins with each of the seven players controlling one of the powers in Europe in the year 1901. Their objective is to gain control of at least half of the game board. To succeed in this challenge, players must cooperate, negotiate, trust and support each other, while also competing for as much territory as possible.
The basics of Diplomacy:
The goal is to control the majority of the map on the game board.
Players negotiate alliances and support each other through private, one-to-one conversations.
There are no binding agreements, so players can misrepresent their plans and double-deal.
After negotiations, players write down their moves which are then executed simultaneously (and trust that others do what they said they would).
The only way to win is by building trust, negotiating and cooperating with other players.

RESEARCH
A breakthrough in cooperative AI
The research breakthrough we call CICERO rests in the achievement of combining two different areas of AI: strategic reasoning and natural language processing. But that’s only part of the story. Visit the CICERO project page for more about how the agent can perform at a human level.
