The 2025 Chatbot Chess Championship featured generative AI chatbots, including ChatGPT, competing against the professional chess engine Stockfish. The tournament highlighted the differences between pure AI, designed for specific tasks, and generative models, which create new content based on prior data. In the initial matches, Snapchat AI showcased erratic behavior, making illegal moves such as capturing its own pieces and moving pawns sideways. Meanwhile, in a showdown between Gemini and Grok, Grok blundered its pieces but ended up accidentally winning by delivering checkmate. A notable match between Meta AI and ChatGPT witnessed mind-bending moves, including Meta controlling ChatGPT's pieces before ChatGPT finally secured victory. The finals pitted Stockfish against ChatGPT, where the contrast was clear: Stockfish played methodically while ChatGPT opted for nonsensical moves resulting in self-destruction. Ultimately, Stockfish was crowned champion, illustrating the effectiveness of structured AI over generative randomness in chess.
