OpenAI beats Elon Musk’s Grok in AI chess tournament final

OpenAI’s AI model 03, developed by the creators of ChatGPT, wins AI chess tournament undefeated

In the final, OpenAI 03 outperformed Elon Musk’s xAI Grok 4. Google’s Gemini model took third place, followed by another OpenAI model.

According to the report, the AI chess tournament was held on Kaggle — a Google-owned platform that allows data specialists to test their systems through competitions. Eight major U.S. large language models from Anthropic, Google, OpenAI, and xAI, as well as China’s DeepSeek and Moonshot AI, competed against each other during the three-day Kaggle event.

Notably, tech companies have often used chess to gauge a computer’s progress and capabilities. Modern chess engines at full strength are unbeatable even against the best human players.

However, this competition did not involve computers specifically designed to play chess — instead, it was held between AI programs built for everyday use. These AIs, while advanced and skilled in many daily tasks, are still improving at chess. For example, Grok made a series of blunders in the final games, repeatedly losing its queen.

Before the final, Musk wrote on X that xAI’s earlier success in the tournament was a “side effect” and that the company had “spent almost no effort on chess.”

This is a side effect btw. @xAI spent almost no effort on chess. https://t.co/p18DFFn35A
