Yes, Claude can do Nine Loops

Physicist-turned-science-writer Matt von Hippel challenged AI companies to solve a difficult problem in theoretical physics—computing scattering amplitudes in N=4 super Yang-Mills theory to nine loops—using only the computational resources available to academic researchers. He issued this challenge to test whether AI could tackle genuinely hard computational problems that researchers had avoided due to resource limitations, and according to the article's title, Claude successfully completed this task within a month of the challenge being issued.
