Summary Report
Anthropic's Fable 5.1 computed the nine-loop six-particle amplitude in planar N=4 super-Yang-Mills, beating the eight-loop record, verified by Lance Dixon.
- 01. Previous record was eight loops, set by SLAC's Lance Dixon and collaborators
- 02. Fable 5.1 ran largely unsupervised for days in Claude Science for $1,000-2,000; Dixon verified the result
Physicists predict particle collisions using scattering amplitudes, calculated in layers called loops, each one exponentially harder. The record in planar N=4 super-Yang-Mills was eight loops, set by SLAC's Lance Dixon and colleagues. After a challenge from physicist Matt von Hippel, Fable 5.1 ran largely unsupervised for days in Claude Science from a single prompt and computed the nine-loop result for $1,000 to $2,000. Dixon independently verified it. It used known methods rather than new physics.
