Chess Meets AI: How Language Models Play the Game

Chess Meets AI: How Language Models Play the Game
Over the past year, there has been a fascinating development in the interaction between large language models (LLMs) and chess, a domain traditionally dominated by specialized algorithms. Originally not designed for gameplay, LLMs have shown surprising capabilities in understanding and playing chess through natural language processing alone. This ability suggests that these models might be building internal representations of the game far beyond their primary training objectives.

In recent experiments, various models, including those from OpenAI’s lineup and others like Llama and Qwen, have been tested against chess engines like Stockfish. The results were overwhelmingly skewed towards poor performance, with nearly all models except gpt-3.5-turbo-instruct showing an inability to compete effectively, even on lower settings. This particular model, gpt-3.5-turbo-instruct, displayed a striking exception by not only understanding standard chess openings but also securing wins against advanced settings of Stockfish.

The approach used to test these models involved prompting the LLMs to suggest moves in standard algebraic chess notation without turn numbers or explanations, simulating the input one might expect in a casual game of chess. This methodology is rooted in the way humans often engage with text-based chess problems, suggesting that LLMs might use contextual understanding derived from vast datasets that include recorded chess games.

Interestingly, the quality of chess play by LLMs appears to degrade with instruction tuning, which typically enhances a model’s conversational abilities. This could imply a trade-off where models optimized for human-like interaction lose their edge in structured tasks like chess.

Theories about why only one model excelled range from the possibility of its training on a disproportionately high number of chess texts to differences in model architecture or the potential for interference from other data types during training. This raises intriguing questions about the adaptability of LLMs and their potential to develop specialized skills “accidentally.”

Further investigation into how LLMs process and generate responses based on chess notation might offer insights into broader applications of AI in other fields where pattern recognition and strategic planning are crucial.

This exploration into LLMs and chess not only broadens our understanding of the capabilities of these models but also highlights the unforeseen ways in which AI can intersect with human activities, even those as structured and rule-bound as chess.
