- OpenAI’s o3 mannequin gained a five-day poker match of 9 AI chatbots
- The o3 mannequin gained by taking part in probably the most constant recreation
- Most prime language fashions dealt with poker properly, however struggled with bluffing, place, and fundamental math
In a digital showdown not like something ever dealt on the felt, 9 of the world’s strongest massive language fashions spent 5 days locked in a high-stakes poker match.
OpenAI’s o3, Anthropic’s Claude Sonnet 4.5, X.ai’s Grok, Google’s Gemini 2.5 Professional, Meta’s Llama 4, DeepSeek R1, Kimi K2 from Moonshot AI, Magistral from Mistral AI, and Z.AI’s GLM 4.6 performed 1000’s of palms of no-limit Texas maintain ’em at $10 and $20 tables with $100,000 bankrolls apiece.
When OpenAI’s o3 mannequin walked away from a weeklong poker recreation $36,691 richer, there was no trophy, simply bragging rights.
The experimental PokerBattle.ai was solely AI-run with the identical preliminary immediate issued to every participant. It was pure technique, if technique is what you name 1000’s of micro-decisions made by machines that don’t actually perceive profitable, dropping, or how humiliating it’s to bust with seven-deuce.
For a tech stunt, it was unusually telling.

Whereas they didn’t play flawless poker, they got here impressively near mimicking seasoned gamers’ judgment calls.
OpenAI’s o3 rapidly confirmed it had the steadiest hand, taking down three of the 5 largest pots and sticking near textbook pre-flop principle. Anthropic’s Claude and X.com’s Grok rounded out the highest three with substantial earnings of $33,641 and $28,796, respectively.

It’s a mirror of real-world decision-making in the whole lot from enterprise negotiations to navy technique, and now, apparently, chatbot growth.
One constant takeaway from the match was that the bots had been usually too aggressive. Most favored action-heavy methods, even in conditions the place folding would have been wiser. They tried to win huge pots greater than they tried to keep away from dropping them. They usually had been terrible at bluffing, not as a result of they didn’t attempt, however as a result of their bluffs usually stemmed from misinterpret palms, not intelligent deception.
Nonetheless, AI instruments are getting smarter in ways in which go far past surface-level smarts. They’re not simply repeating what they’ve learn; they’re making probabilistic judgments below strain and studying to learn the room. It’s additionally a reminder that even highly effective fashions nonetheless have flaws. Misreading conditions, drawing shaky conclusions, and forgetting their very own “place” isn’t only a poker drawback.
You would possibly by no means sit throughout from a language mannequin in an actual poker site, however odds are you’ll work together with one making an attempt to make choices that matter. This recreation was only a glimpse of what that might seem like.
