Claude performs complex nine-loop physics calculation

01 What happened

Anthropic announced that its Claude model successfully computed the six-particle amplitude in planar N=4 super Yang-Mills theory to nine loops. According to the company, the calculation was executed via Claude Science with minimal human intervention, requiring only basic prompts to continue.

02 Key details

• The model achieved the nine-loop MHV six-particle amplitude calculation without sophisticated oversight.
• A human expert in the field independently verified the accuracy of the result produced by the AI.

03 Why it matters

The case shows an AI agent completing a difficult, independently checked calculation using known methods and affordable computing resources. It concerns a toy-model theory and does not establish a general ability to bypass computational limits in physics.

04 Who it matters to

Theoretical physics researchers, machine learning engineers and AI tool developers.
