Claude Science hits nine-loop N=4 SYM amplitude for ~$1–2k
Anthropic physicists pointed Claude (Fable 5.1) in Claude Science at Matt von Hippel’s challenge and produced the six-particle MHV amplitude in planar N=4 super-Yang-Mills at nine loops—validated by Lance Dixon—for roughly $1–2k per run with almost no mid-run scientific guidance.
