OpenAI beats Elon Musk's Grok in AI chess tournament

OpenAI has claimed victory over Elon Musk's Grok in a recent artificial intelligence chess tournament, marking a significant moment in the ongoing rivalry between the two tech giants. The competition was not about specialized chess computers, but rather about AI models designed for everyday tasks, such as answering questions and helping users online. OpenAI's o3 model remained undefeated throughout the tournament and ultimately defeated xAI's Grok 4 in the final match. This win has added more fuel to the competitive fire between OpenAI and xAI, both of which were co-founded by Sam Altman and Elon Musk.

The tournament took place on Kaggle, a platform owned by Google that hosts data science competitions. Eight large language models participated, including those from Anthropic, Google, OpenAI, xAI, and Chinese developers DeepSeek and Moonshot AI. Over three days, these AI models played chess against each other, testing their ability to strategize and make decisions. Google's Gemini model secured third place after defeating another OpenAI model. While these AI systems are highly capable in many areas, they are still learning to master chess. Grok, for example, made several errors during its final games, such as repeatedly losing its queen, which is a crucial piece in chess.

Chess experts and fans closely followed the tournament. Pedro Pinhata from Chess. com noted that Grok seemed unbeatable until the final day, when its performance suddenly declined. He described Grok's play as 'unrecognizable' and full of mistakes, which allowed OpenAI's o3 model to win convincingly. Chess grandmaster Hikaru Nakamura commented during his livestream that OpenAI avoided the blunders that Grok made. Elon Musk responded by saying that xAI had not focused much on chess, and its earlier success was just a 'side effect. ' Chess and other strategy games like Go have long been used to measure the progress of AI, as they require complex reasoning and planning. In the past, computers like IBM's Deep Blue and Google's AlphaGo have defeated top human players, demonstrating the growing power of artificial intelligence. This latest tournament shows that AI models are becoming more skilled, not just in games, but in many aspects of everyday life.
