BlockBeats reported that on August 14, last week, OpenAI's o3 model defeated xAI's Grok 4 in the AI chess competition, winning the championship. The competition, called 'AI Chess Showcase', was held on Google's Kaggle platform, where eight AI models competed in a three-day knockout tournament to determine the top three.
The competition required the AI model to play chess without any specialized training, only able to gather some chess knowledge from the internet before the competition. In the finals, OpenAI's o3 defeated Grok 4 with a score of 4-0, winning the championship. It is worth mentioning that o3 had a score of 4-0 in all three matches and also swept its fellow o4 mini in the semifinals.
Earlier this year, in another tournament hosted by chess master Levy Rozman, both Grok and ChatGPT lost to the AI system Stockfish, which was specifically designed for chess.
