Noam Brown is a Research Scientist at OpenAI specializing in AI reasoning and game-theoretic AI systems. He is known for developing superhuman AI agents across complex domains, including the Libratus and Pluribus poker AIs, the CICERO Diplomacy AI, and most recently OpenAI's o1 and o3 reasoning models. His research focuses on scaling inference-time computation and human data imitation as core techniques for advancing frontier AI capabilities, while maintaining engagement with questions around AI ethics, capability assessment, and the societal implications of AI-generated content.
Today, we at @OpenAI achieved a milestone that many considered years away: gold medal-level performance on the 2025 IMO with a general reasoning LLM—under the same time limits as humans, without tools
