Claude one-shots a nine-loop scattering amplitude, a frontier physics calculation
Dr_Singularity · x · 2026-09-26
Claude from Anthropic autonomously computed a nine-loop scattering amplitude in N=4 super Yang-Mills — a frontier calculation top physicists had been working toward and considered too difficult to attack directly.
- It used established physics methods, wrote the necessary code from scratch, ran the computation two different ways, and reached an independently validated result.
- It required almost no scientific hand-holding beyond "keep working."
- The full run would cost an end user only about $1,000-$2,000.
- The author describes it as a major jump from AI doing student-level physics projects earlier this year to autonomously completing real frontier research.
