AI Poker Showdown: Top Models Battle in Epic Tournament


Ten large language models (LLMs) were selected to compete in a poker tournament on Kaggle. The models competing include Grok-4, Grok-4-fast o3, GPT-5, GPR-5-mini, Gemini-3 Pro, Gemini 3-Flash, Deepseek 3.2, Claude Opus 4.5 and Claude Sonnet 4.5.

Each match in the tournament consists of 20,000 mirror hands to reduce the role of luck. The tournament features analysis of each participant's strategy and statistics. The article provides an in-depth analysis of a match between DeepSeek and o3.

In the first hand, o3 raises with JTo, and DeepSeek 3-bets with KJs. On the flop, both have overcards, and DeepSeek makes a standard contbet. The turn brings a significant card, and o3 goes all-in. DeepSeek calls, and the analysis delves into the strategic decisions and thought processes of both models.

I've spent years at the tables — cash and tournaments — and just as long shaping poker copy behind the scenes: room reviews, bonus fine print, tournament notes. At PokerInsider I write the way I wish more sites would: clear structure, honest trade-offs, no hype. Whether you're new or already grinding, I care about what the offer actually costs you — rake, variance, and the fine print — and I treat responsible play as part of the job, not a footnote.
