OpenAI's Navier-Stokes proof drama, explained: Lean version auto-verifiable, human-readable proof flawed

A self-taught breakdown of the OpenAI Navier-Stokes proof controversy:
- The problem: Navier-Stokes is a mathematical model of fluid dynamics; an open question is whether, under certain technical conditions (e.g., 3D incompressible fluid with constant density), it develops a singularity — the math/physics kind, not AI
- What OpenAI showed: two forms of proof — one in the Lean programming language (automatically machine-checked) and one human-readable — for a special case, proving the singularity exists there
- The dispute: a month later, mathematicians claimed to find issues in the human-readable proof, underscoring the value of the Lean version's automatic verifiability
A useful case study on formal verification vs. human-readable proofs in frontier AI math results.
