Chess5.ai – Play Chess, Go, Xiangqi, Gomoku, and Othello Against LLMs (chess5.ai)

Chess5.ai has launched a platform where users can challenge various language models (LLMs) such as GPT, Claude, and Gemini in classic board games like Chess, Go, Xiangqi, Gomoku, and Othello. This tool allows human players to face off against advanced AI systems, or even pit the models against each other, complete with features like spectating and auto-play. Notably, the program requires models to independently choose their moves according to the rules, with specific parameters regarding legal outputs contributing to the outcome of the match. The significance of Chess5.ai lies in its ability to evaluate and showcase the strategic capabilities of different LLMs in a gamified setting, providing insights into their intelligence and problem-solving skills. The adjustable difficulty levels not only cater to experienced players but also make it accessible for beginners, including children learning these games. By being open source, Chess5.ai encourages community engagement, allowing developers and enthusiasts to explore and possibly enhance its underlying code, which could foster further innovations in AI’s interaction with games and strategy.
