Claude reportedly solves a nine-loop physics calculation in a simplified model
Anthropic says Claude worked largely unsupervised for days from a single prompt, at a cost of a few thousand dollars. The company says physicist Lance Dixon independently verified the result.
TLDR
Anthropic reports that Claude solved a nine-loop scattering-amplitude problem in planar N=4 super-Yang-Mills, a simplified physics model where the previous record was eight loops. Scattering amplitudes help physicists predict particle behavior; “loops” add increasingly precise corrections at exponentially greater computational cost. The company says Claude ran largely unsupervised for days in Claude Science after a single prompt, using methods developed by SLAC physicist Lance Dixon and collaborators. Anthropic puts the cost at a few thousand dollars and says Dixon independently verified the result.
