GPT-6-Astra solves 49 of 50 physics research problems at $2.40 apiece
On the TheoPhysEval benchmark, GPT-6-Astra matched leading specialists on 49 of 50 unpublished theoretical physics calculations, and some apparent failures exposed errors in the experts' own answers. The researchers say physics has not yet seen a breakthrough like mathematics because the agents lack taste, but they think autonomous top-level AI research could come soon.
