OpenAI's o3 model triumphed over xAI's Grok 4 in a significant AI chess tournament. Unlike traditional chess engines, these AI were designed for general tasks. Grok, initially seen as a strong contender, made repeated mistakes during the final game, leading to OpenAI's convincing victory. Google’s Gemini secured third place after defeating another OpenAI model. Both Musk and Altman have claimed their AIs are among the smartest globally, while acknowledging improvements needed in chess-playing capabilities.
"Up until the semi finals, it seemed like nothing would be able to stop Grok 4 on its way to winning the event. Despite a few moments of weakness, X's AI seemed to be by far the strongest chess player... But the illusion fell through on the last day of the tournament."
"Grok made so many mistakes in these games, but OpenAI did not," said chess grandmaster Hikaru Nakamura during his livestream on the final.
Musk had said in a post on X that xAI's prior success in the tournament had been a 'side effect' and it 'spent almost no effort on chess.'
OpenAI's o3 model emerged unbeaten in the tournament and defeated xAI's model Grok 4 in the final, adding fuel to the fire of an ongoing rivalry between the two firms.
