Big win for verifiable AI.

Formal Math proof is starting to scale like software.

@axiommathai rewrote the longest proof in mathematics, all 15,000 pages, about 40 million lines of Lean.
Swarms of AI agents wrote it in 24 days while mathematicians steered them.

Axiom says that at the start of this year, getting AxiomProver to write a correct 10,000-line Lean proof took weeks of coaxing. And now this swarm of agents formalized a problem roughly 4,000 times that size in 24 days.

The target was the Classification of Finite Simple Groups: about 15,000 pages, 500+ papers, around 100 authors, and no single reader who has gone through all of it.

Axiom credits the jump to rebuilding three layers at once: the models, the harness and the infrastructure.
