OpenAI Extends Its Gluon Result to Gravitons

OpenAI published a follow-up to its February gluon scattering paper, extending the single-minus amplitude formulas from gluons to gravitons - the hypothetical quantum carriers of gravity. The original result, where GPT-5.2 identified a closed-form formula for gluon scattering that physicist Nima Arkani-Hamed had pursued for fifteen years, already landed on arXiv with a machine-generated proof verified by human researchers. Moving to gravitons broadens the result into quantum gravity territory, with supersymmetric generalizations also reportedly underway. The paper is co-authored by researchers from the Institute for Advanced Study, Harvard, Cambridge, and Vanderbilt alongside OpenAI staff. AI labs publishing peer-reviewed physics results - not just assisting researchers but generating proofs - marks a qualitative shift in how frontier models are being positioned.
