Positioned as an exploration into the suitability of transformer architectures for chess AI, demonstrating that a small model combined with an MCTS harness can achieve a strong Elo rating (~2100).
This project explores the application of transformer architectures to traditional AI problems like chess, a domain typically dominated by search algorithms. The key insight is that while the transformer model provides strong heuristics, the MCTS harness is critical for achieving competitive performance (~2100 Elo). This highlights a broader trend in AI development: the synergy between deep learning models for pattern recognition and classical AI techniques for planning and search. For B2B SaaS, this implies that hybrid AI solutions, combining the strengths of different paradigms, will likely yield more robust and performant systems. Companies developing AI agents or decision-making systems should consider integrating specialized models with sophisticated control or search mechanisms rather than relying solely on end-to-end deep learning. The project also demonstrates the value of open-source contributions for validating novel architectural approaches in AI.
Hi HN!I build this project to explore an idea I got in mind for a long time : Is transformer a suitable architecture for a chess bot? I built a small model (11M parameters) and trained it on human games (Elite Lichess DB).Model alone is performing around 1500 elo, but I built an harness using Monte Carlos Tree Search (MCTS) using my model heuristics to improve the model to ~2100 elo (evaluated against stockfish).If you want to try it, it is available as a Lichess bot : https://lichess.org/@/ChessTransformerBotI'm looking to evaluate this model against human players so challenge, I would be grateful if you try it!The project is open source, don't hesitate to star the repos if you like the project.For me, the main key learning is that machine learning is an important part of the project, but it was the harness design that makes the system works with a nice performance regarding the small model size.
