DipLLM is a fine-tuned Large Language Model (LLM) designed for strategic decision-making in Diplomacy, a complex multiplayer game that combines cooperation and competition.
Traditional methods for AI in Diplomacy rely on equilibrium search, requiring extensive game data and computational resources.
LLMs offer an alternative by leveraging pre-trained knowledge for strong performance with limited fine-tuning.
However, applying LLMs to Diplomacy is challenging due to the game's complexity and strategic interactions among players.
DipLLM simplifies the task by using an autoregressive factorization framework to break down multi-unit action assignment into unit-level decisions.
The model fine-tunes by learning equilibrium policies and outperforms the Cicero model with only 1.5% of the training data.
This research demonstrates the potential of fine-tuned LLMs for complex strategic decision-making in multiplayer games.
