Claude runs unsupervised for days, breaks a physics record
Anthropic researchers gave Claude a one-line prompt: extend a known calculation in particle physics, the six-particle scattering amplitude in a theory called planar N=4 super Yang-Mills. Then they mostly let it run. Over several days of largely unsupervised work, Claude computed a nine-loop result, beating the eight-loop record a SLAC physicist had held since 2023 — who then independently verified the new result himself. Total compute cost: $1,000 to $2,000. It used two established techniques rather than inventing something new.
On your desk: it's the clearest number yet for what a long, loosely supervised Claude Code run can do for a few thousand dollars — the same shape of task as pointing it at a multi-day ghostwriting pass on the dance memoir or a big Skool content migration, then checking back in a few days instead of a few hours.
