“An agent that can play at the level of humans in a game as strategically complex as Diplomacy is a true breakthrough for cooperative AI.”

Yann LeCun

VP & Chief AI Scientist, AI at Meta

By building CICERO, AI at Meta has created the first AI agent to achieve human-level performance in the complex natural language strategy game Diplomacy*. CICERO demonstrated this by playing with humans on webDiplomacy.net, an online version of the game, where CICERO achieved more than double the average score of the human players and ranked in the top 10% of participants who played more than one game.

This breakthrough rests in the achievement of combining two different areas of AI: strategic reasoning and natural language processing. The integration of these techniques gives CICERO the ability to reason and strategize with regard to players’ motivations, then use natural language to communicate, reach agreements to achieve shared objectives, form alliances and coordinate plans.
