- OpenAI’s o3 defeated Elon Musk’s Grok 4 at chess
- Magnus Carlsen delivered biting commentary on the standard of Grok’s logic
- Grok 4 made repeated blunders, whereas o3 performed regular
The AI chess match between OpenAI’s o3 mannequin and xAI’s Grok 4 invited loads of hypothesis as a sort of proxy battle between the 2 firms and their respective CEOs. Any comparability to the times of Deep Blue and Bobby Fischer quickly pale, although, as OpenAI o3 repeatedly worn out Grok 4, successful 4 video games in a row, accompanied by the derisive commentary of former world chess champion Magnus Carlsen and grandmaster David Howell.
The showdown occurred on Kaggle’s Sport Enviornment, a digital coliseum the place AI fashions battle in chess and different video games. The match featured eight of essentially the most outstanding LLMs within the enterprise: OpenAI’s o3 and o4-mini, Google’s Gemini 2.5 Professional and Flash, Anthropic’s Claude Opus, Moonshot’s DeepSeek and Kimi, and xAI’s Grok 4. The ultimate got here right down to Grok and o3, however Grok’s efficiency within the closing spherical did not look like a battle of champions.
Carlsen and Howell veered between severe commentary and a roast as Grok’s efficiency got here off as considerably erratic. Within the first sport, it shortly sacrificed its bishop, then started buying and selling items prefer it was in a rush to go dwelling. Issues did not enhance within the subsequent sport for Grok.

“[Grok] is like that one man in a membership match who has learnt idea and actually is aware of nothing else,” Carlsen mentioned in the course of the second sport. “Makes the worst blunders after that.”
Grok’s efficiency was so off-the-rails that Carlsen rated it round 800 ELO, or barely above a newbie. He gave o3 a modest however respectable 1200, in the course of most pastime gamers. Although o3 didn’t play brilliantly, it didn’t need to. It performed stable chess. It didn’t blunder items. It transformed its benefits and carried out the traditional chess strikes.
“o3 is pretty ruthless in conversions; it seems like a chess participant. Grok seems prefer it learnt a number of opening strikes and is aware of the foundations, however not far more.,” Carlsen mentioned. “Grok’s strikes are chess-related strikes. They simply got here on the fallacious time and in bizarre sequences.”
Chess AI
The chess wasn’t the principle level of the match, regardless of its prominence. It was about how general-purpose AI fashions deal with occasions with strict guidelines like chess video games. Seems, they are not nice, however o3 is the very best of the restricted pattern. As AI turns into embedded in the whole lot, the flexibility to comply with guidelines and spot patterns turns into important. Chess is a uniquely clear approach to observe that. You both made the proper transfer otherwise you didn’t. When a mannequin performs effectively, you’ll be able to see the logic; in any other case, queens fall like dominoes, and the sport turns into as confused as that metaphor.
Chess is a window into how effectively an AI can plan, consider choices, keep away from catastrophic errors, and keep logically constant. If Grok throws away a queen as a result of it doesn’t grasp long-term penalties, what would possibly it do in a authorized doc, or when reserving journey?
That the ultimate was between OpenAI and xAI did add some drama with Sam Altman and Elon Musk at loggerheads in public. The chess closing didn’t resolve the battle between them, but it surely did give OpenAI a PR win within the realm of public notion, and a restricted however very actual praise from Magnus Carlsen.
