Claude reportedly solves a nine-loop calculation in a simplified physics model
Anthropic says Claude worked largely unsupervised for days at a cost of a few thousand dollars. The company says SLAC physicist Lance Dixon independently verified the result.
TLDR
Anthropic says Claude solved a nine-loop problem in planar N=4 super-Yang-Mills, a simplified model physicists use as a testing ground. The calculation concerns scattering amplitudes, formulas used to predict particle behavior. Each “loop” adds a finer correction but requires exponentially more computation; Anthropic says the previous record in this model was eight loops. Given a single prompt, Claude ran largely unsupervised for days in Claude Science, using methods developed by SLAC physicist Lance Dixon and colleagues. The company puts the cost at a few thousand dollars and says Dixon independently verified the result.
