Extending single-minus amplitudes to gravitons

Summary

OpenAI science application post from March 2026 documenting GPT-5’s contribution to theoretical physics — specifically extending scattering amplitude calculations (single-minus helicity configurations) to graviton interactions in quantum gravity. Scattering amplitudes are mathematical objects describing particle interactions; their computation for gravitons is technically demanding. The post documented a collaboration between OpenAI models and theoretical physicists, where GPT-5’s mathematical reasoning capabilities helped derive or verify amplitude expressions.

Implications

Frontier theoretical physics as a capability demonstration. Scattering amplitudes in quantum gravity sit at the intersection of quantum field theory and general relativity — among the most technically demanding computations in theoretical physics. OpenAI using this as a showcase application made a strong claim about GPT-5’s mathematical reasoning depth, complementing the genetics and social science applications with a physics case.

Thread: AI in science. Sits alongside the genetics collaboration (September 2024), the protein synthesis cost reduction (February 2026), and the GPT-5.2 science and math post as OpenAI’s portfolio of frontier science applications demonstrating that GPT-class models had crossed a threshold of usefulness for research in technical domains.

Watch: Whether the amplitude results were published in peer-reviewed physics journals and whether theoretical physicists independently validated the mathematical contributions, or whether the post remained a demonstration without external validation.
