Introduction

In a recent publication, meta AI introduced Cicero, a new AI agent specifically developed to play the game of diplomacy. This game requires complex discourse, alliances, and negotiation, making it an ideal benchmark for testing AI systems. Cicero has impressed experts with its ability to outperform human players, achieving double the average score and ranking in the top 10 percent of participants. The agent integrates language modeling, planning, and reinforcement learning algorithms to infer players' beliefs and intentions from conversations and generate dialogue to pursue its plans. This article delves into the details of Cicero and explores its capabilities in the realm of diplomacy.

The Game of Diplomacy

Before diving into Cicero's intricacies, it is essential to understand the game it was designed to play—diplomacy. Diplomacy is a game that simulates the geopolitical landscape of Europe leading up to World War I. Each player takes control of a country and aims to conquer most of Europe by capturing supply centers. Diplomacy involves strategic moves, negotiations, and alliances between players. The game's complexity arises from the need for players to discuss and coordinate their actions in secret, making effective communication a crucial aspect of the game.

Challenges in Multi-Agent Learning

While most AI successes have been in purely adversarial environments like chess and go, diplomacy poses a unique set of challenges for multi-agent learning. Previous approaches to multi-agent learning mainly relied on Supervised learning with labeled data. However, diplomacy requires agents to engage in complex negotiations and maintain human-compatible language and behavior, which cannot be achieved through supervised learning alone. Thus, developing an AI agent capable of playing diplomacy effectively is a significant challenge.

Cicero: An AI Agent for Diplomacy

Cicero was designed to address the challenges of multi-agent learning in the Context of diplomacy. The AI agent combines a dialogue module with a strategic reasoning module and employs a filtering process to reject low-quality messages. Cicero leverages a planning algorithm, reinforcement learning, and self-play to predict other players' policies, select optimal actions, and generate human-interpretable dialogue. The language model used by Cicero was trained on a vast dataset comprising millions of messages exchanged between human players during diplomacy games.

The Design and Architecture of Cicero

To understand Cicero's inner workings, it is crucial to explore its design and architecture. The agent utilizes a 2.7 million parameter language model initially pre-trained on internet text data. This model is then fine-tuned using a dataset of 925,000 diplomacy games from webdiplomacy.net. Cicero combines its dialogue and strategic reasoning modules to generate high-quality, controlled dialogue. The use of intents allows the AI agent to portray its plans, coordinate with allies, and understand the intentions of other players.

Strategies and Techniques Used by Cicero

Cicero employs several strategies and techniques to excel at diplomacy. The agent's planning module uses self-play reinforcement learning to predict the policies of other players Based on the game state and dialogue history. It then selects optimal actions based on these predictions. Cicero's message generator includes filters to ensure the generated messages are sensible, consistent with intents, and strategically sound. The agent's ability to control its dialogue and plan its actions is pivotal in its success during diplomacy games.

Evaluation of Cicero's Performance

The performance of Cicero was evaluated through a series of games in an anonymous online diplomacy league. The AI agent consistently outperformed human players, achieving a score double the average and ranking among the top 10 percent of participants. While Cicero participated in blitz league matches with short negotiation periods, the results indicate its potential for success even in longer and more complex negotiation formats. The team behind Cicero acknowledges the need for further challenges and evaluations to push its capabilities to the limit.

Comparison with Other AI Agents

Cicero's success in playing diplomacy presents a significant advancement in multi-agent learning. While previous AI agents have excelled in purely adversarial games, diplomacy's emphasis on negotiation and communication adds a layer of complexity. Cicero's performance outshines other AI agents in the context of diplomacy, highlighting the potential of incorporating multi-agent learning in more intricate domains.

Future Implications and Considerations

The development of Cicero and its success in diplomacy raises several intriguing possibilities for the field of AI. The agent's ability to understand complex dialogue and plan actions based on other players' intents opens avenues for practical applications beyond the realm of games. Moreover, Cicero's performance showcases the importance of balancing self-play algorithms with human-compatible language and behavior. Future research can explore ways to enhance the agent's negotiation skills and adapt it to more intricate real-world scenarios.

Conclusion

Cicero, the AI agent developed by meta AI, demonstrates remarkable capabilities in playing the game of diplomacy. By combining language modeling, strategic reasoning, and reinforcement learning, Cicero outperforms human players and achieves high scores in anonymous online diplomacy leagues. The agent's ability to generate human-interpretable dialogue, plan actions effectively, and understand the intentions of other players propels it to the top ranks in the domain of multi-agent learning. Cicero's success in diplomacy opens doors for further advancements in AI and paves the way for applications in complex, real-world scenarios.
