Anthropic's Claude AI Computes Nine-Loop Amplitude in Super-Yang-Mills Theory

Anthropic announced that its AI model, Claude, successfully computed a nine-loop amplitude in N=4 super-Yang-Mills theory. This complex particle physics calculation had reportedly stumped human researchers for years. Anthropic stated that Claude achieved this breakthrough with minimal input and at a low computational cost, reportedly a few thousand dollars. The primary source for this achievement is Anthropic itself, with other outlets reporting on the company's claims. This event highlights the AI's capability in advanced theoretical physics research.
