One Prompt, Days of Autonomous Running: Claude Solves Nine-Loop Amplitude for ~$100 of Compute
AI寒武纪 · wechat · 2026-09-26
Anthropic's ClaudeScience platform, powered by Fable 5.1, computed the nine-loop six-particle amplitude in planar N=4 super-Yang-Mills with almost no human intervention, surpassing the eight-loop record set by Lance Dixon's team in 2023. Researchers gave one initial prompt plus "keep going" instructions; Claude wrote all Python/SymPy code from scratch, solved it via two independent mathematical routes, spent $100 on symbolic compute ($1-2K total), and Dixon spent two weeks verifying the result—concluding Claude understands his team's papers better than any human reader. A CAS team led by Song He independently obtained most of the nine-loop symbol data days later, using GPT-6 only for auxiliary constraints. von Hippel's reflection: the bottleneck was never raw compute but humans' efficiency at coding and orchestration.
