Claude reportedly completes a nine-loop particle-physics calculation

GlobalFeedAI, citing a guest post on Anthropic’s site, says the calculation went beyond an earlier eight-loop result. The theory is a toy model that does not describe the real world.

TLDR

GlobalFeedAI, citing a guest post on Anthropic’s site, says Claude completed a nine-loop scattering-amplitude calculation, extending an earlier eight-loop result. The account says the main calculation ran on 96 CPUs for a week and physicist Lance Dixon checked it. The guest-post author says Claude used known methods and no new method came out of the work.

Global Feed AI@GlobalFeedAIClaude has completed a nine-loop calculation in particle physics, according to a guest post on Anthropic's site. What is it? A scattering amplitude tells how likely particles are to react in a certain way. More "loops" means a more exact and much harder calculation. The earlier result for this one stopped at eight loops. How was it done? Anthropic physicists gave Claude a one-sentence task and told it to keep going. The main calculation ran on 96 CPUs for a week. Physicist Lance Dixon checked the result. Good to know The theory is a toy model. It does not describe the real world. The author says Claude used known methods, and no new method came out of it. A group at the Chinese Academy of Sciences computed a key piece of the same result around the same time, with help from GPT-6. Anthropic invited the author to write the post and paid him for his time. @AnthropicAI #AI #Physics #Science #Claude12d
Melothemyth@Melothemyth777a former theoretical physicist dared AI labs to push a particle physics calculation from eight loops to nine. a month later, Claude came back with the result. roughly $1–2k to run. a physicist who helped develop the earlier method checked it himself. the strange bit is how Claude got there. it read their papers, wrote the code, used their method and kept working while the researchers slept. the physicist said Claude may understand those papers better than almost anyone outside the people who wrote them. the method was theirs. the ninth loop came back while they slept.12d
