OpenAI researchers and collaborators have published a preprint showing that single-minus graviton tree amplitudes are nonzero under special kinematic conditions (the half-collinear regime), challenging long-held assumptions. Notably, GPT-5.2 Pro was used to derive the gravitational extension from prior gluon results, representing a significant AI-assisted breakthrough in theoretical physics.
GPT-5.2 assisted in deriving a new theoretical physics result showing that single-minus gluon tree amplitudes can be nonzero under specific half-collinear momentum conditions, challenging decades of assumptions in particle physics. The AI model identified patterns in complex Feynman diagram expressions and conjectured a general formula that was subsequently verified through formal proofs.
Physicist Matt von Hippel challenged AI companies to solve a computational problem in theoretical physics, and Claude from Anthropic successfully computed a nine-loop amplitude in N=4 super-Yang-Mills within a month.
