GPT-5.2 Proves Decades-Old Physics Assumption Wrong
OpenAI announced on February 13, 2026 that GPT-5.2 derived a new result in theoretical physics, overturning a decades-old assumption about gluon amplitudes. The work, titled "Single-minus gluon tree amplitudes are nonzero," was co-authored by researchers from the Institute for Advanced Study, Vanderbilt University, University of Cambridge, Harvard University, and OpenAI. The discovery shows that certain particle interactions physicists expected would not occur can actually arise under specific conditions.
The Discovery Challenges Fundamental Assumptions About Gluons
For decades, physicists assumed that certain gluon amplitudes called "single minus" were zero, and that maximally helicity violating amplitudes had two gluons of one helicity and n-2 of the other. Gluons are the particles that carry the strong nuclear force, one of the four fundamental forces in physics. GPT-5.2's work demonstrates this long-held assumption was incorrect.
The final formula was first conjectured by GPT-5.2 Pro. An internal scaffolded version of GPT-5.2 then spent approximately 12 hours reasoning through the problem, independently arriving at the same formula and producing a formal proof of its validity. The model was able to greatly reduce the complexity of expressions whose complexity grows superexponentially, providing much simpler forms.
AI-Assisted Physics Represents New Scientific Methodology
Greg Brockman, OpenAI's President, described the work as demonstrating "great promise in the potential of AI to benefit people by accelerating science." Kevin Weil from OpenAI characterized this as "journal-level research advancing the frontiers of theoretical physics" and "a glimpse into the future of AI-assisted science, with physicists working hand-in-hand with AI to generate and validate new insights."
The research team has already extended these amplitudes from gluons to gravitons with GPT-5.2's assistance, suggesting this methodology could accelerate discoveries across theoretical physics. The announcement generated significant interest in the scientific community, receiving 339 points and 244 comments on Hacker News within hours of publication.
