Astra in Codex solves 50 unpublished physics problems at 98% accuracy
Citing a paper, the post says GPT-6 Astra harnessed in Codex solves 50 unpublished research-level theoretical physics problems with near-perfect 98% accuracy at an average cost under $3 per problem.
Physics is also cooked: “GPT-6-Astra harnessed in Codex, obtains the final answers with a near-perfect accuracy of 98% at an average cost under 3$ per problem.” These are: “suite of 50 unpublished research-level theoretical physics problems with verifiable answers. Without AI assistance, a typical problem in our collection could be solved by a world expert in about a day or less but would take considerably longer for experts in adjacent specialties.”
