Claude AI sets physics record by computing nine-loop scattering amplitude autonomously
Anthropic's AI model Claude successfully computed a nine-loop scattering amplitude in planar N=4 super-Yang-Mills theory, surpassing the previous eight-loop record set by SLAC physicist Lance Dixon and collaborators. The calculation ran largely unsupervised for days on Claude Science after a single prompt, costing a few thousand dollars. Dixon independently verified the result. The achievement demonstrates AI's potential to advance complex theoretical physics computations.

Claude AI Breaks Physics World Record by Solving Nine-Loop Problem Based on Yang Theory
Anthropic has announced that its AI model, Claude, has set a new record in theoretical physics by solving a notoriously difficult calculation in high-energy physics: the nine-loop scattering amplitude. The calculation, based on Chen Ning Yang's theory, was completed with almost no human intervention over several days of continuous operation. This achievement marks a significant milestone in AI's ability to tackle complex scientific problems that have long challenged human researchers. The news was reported by Chinese tech media outlet 新智元 (Xin Zhi Yuan) on September 27, 2026, highlighting Claude's breakthrough in advancing computational physics and demonstrating AI's growing role in fundamental scientific research.
Claude AI model advances particle-physics calculation from 8 loops to 9 loops
A post on X reports that Anthropic's Claude AI model has pushed a frontier particle-physics calculation from 8 loops to 9 loops. The post quotes an unnamed source stating that 'Claude Science accomplished this in one shot, without any scientific oversight more sophisticated than keep going.' It also quotes Lance Dixon, Professor of Particle Physics and Astrophysics at SLAC and Stanford, who independently checked Claude's new 9-loop result. Dixon is further quoted as saying, 'while I'm validating Claude's result, Claude is validating all of our previous work. In fact, I would assert that Claude understands our 2019 and 2023 papers better than any human, aside from my co-authors.' The post attributes the achievement to Claude and highlights the model's autonomous capability in advanced physics research.
Read sourceAnthropic Reports Claude AI Achieves Nine-Loop Calculation in Theoretical Physics, Breaking Previous Record
Anthropic published a blog post stating that its AI model, Claude, successfully completed a nine-loop calculation in a simplified theoretical physics model (planar N=4 super-Yang-Mills theory). This surpasses the previous record of eight loops set by SLAC physicist Lance Dixon and collaborators. The challenge was issued last month by physicist and science writer @4gravitons, asking if an AI could exceed eight loops using an academic-level compute budget. Claude was given a single prompt describing the nine-loop problem and ran largely unsupervised for days in Claude Science, using methods developed by Dixon and his colleagues, at a total cost of a few thousand dollars. Dixon independently verified the result, and von Hippel wrote about the experience for Anthropic's blog. The achievement demonstrates AI's potential to advance complex scientific computations.

Anthropic announced on its scientific blog that its AI model Claude, running largely unsupervised on the Claude Science platform for several days based on a single prompt, successfully completed a nine-loop scattering amplitude calculation in the plane N=4 super Yang-Mills model. The calculation was performed after a challenge from physicist @4gravitons. The total cost of the computation was approximately several thousand dollars. The original blog post provides details on the calculation process, costs, and independent verification, allowing readers to assess Claude's usability for long-duration theoretical physics tasks.
