The competition on LeanEval is fierce. 15 solutions in the last 14 hours. 6 months ago each such solution would be the largest ever made, completely earth-shattering. Now we get one per hour.
Axiom is still in the lead, by three problems. We have 25 million lines of code in our solutions repo, larger than all OpenAI's formalizations, and twice larger than Anthropic's FLT.
To add a bit of clarity about who proved what.
Tristan + Levent: 3d incompressible Euler with forcing
OpenAI: 3d incompressible Euler without forcing
OpenAI: Navier-Stokes with forcing
No one: Navier-Stokes without forcing
Euler equations = Navier-Stokes without viscosity. Forcing means external force. Absence of viscosity and presence of external force make blowup easier to construct. So in the 2x2 grid Tristan+Levent ticked the weakest box, OpenAI ticked the two next weakest, and the strongest is still open.
Navier-Stokes is not over.
