OpenAI's GPT-5.2 has made a breakthrough in theoretical physics by deriving a new formula for a gluon amplitude. A preprint was published showing the result, which was later formally proven and verified by both OpenAI and academic collaborators. The achievement demonstrates the potential of large language models to contribute to scientific research. --- Why it matters: This matters because it shows that AI can be used as a tool in theoretical physics, potentially accelerating discovery and advancing our understanding of fundamental forces.
