According to Anthropic, Harvard physicist Matthew Schwartz guided Claude Opus 4.5 through a graduate-level theoretical physics calculation, demonstrating that while the model does not yet produce original research autonomously, it can significantly speed up complex derivations and error checking (as reported by Anthropic on X). According to Anthropic, the workflow paired human problem decomposition with Claude Opus 4.5 for symbolic manipulation, latex rendering, and step-by-step verification, cutting iteration time and reducing algebraic mistakes. As reported by Anthropic, this suggests near-term business impact in R&D assistive tooling for physics-heavy industries—such as semiconductors, energy, and aerospace—where domain experts can leverage Claude Opus 4.5 to draft calculations, validate intermediate steps, and generate reproducible notebooks.
