ChessGPT

This project is an interactive chess game where players compete against generative AI chatbots that, due to the nature of large language models, gradually hallucinate the board state as the game progresses.

Developed independently using React and Vite, with chess.js handling move validation under the hood.

Inspired by GothamChess, the game embraces the AI's tendency to hallucinate by allowing illegal moves to take effect — pieces teleport to impossible squares, or materializes out of nowhere when the model confidently references pieces that no longer exist.

currently it only has Gemini 3.1 Flash Lite and Gemini 3.5 Flash.
