Yang-Mills Working Group to publish OpenAI’s Lean code for review

A committee led by Nobel laureate David J. Gross plans to release OpenAI's formal proof and its validation as two GitHub repositories A committee of physicists and mathematicians is about to put an AI-generated proof on public display. The Yang-Mills Working Group, headed by Nobel laureate David J. Gross, said on November 9, 2026, that it plans to publish OpenAI’s Lean code and its validation the following day. The release concerns one of the most famous open problems in mathematical physics. It’s a Clay Mathematics Institute Millennium Prize problem centered on quantum Yang-Mills theory, the framework underneath quantum chromodynamics, which describes the strong force. What is being released The working group intends to publish two GitHub repositories on November 10, 2026. The first contains OpenAI’s full Lean code submission. The second is a validation assessment, described as confirming the existence of pure Yang-Mills theory according to established definitions in physics and mathematics. Lean is a proof assistant, a programming environment where a mathematical argument is written so precisely that a computer can verify each step. The timeline runs back a few months. OpenAI pro...
