GPT-6 Astra reportedly scored 98% after disputing expert results on a physics benchmark

A user says GPT-6 Astra initially scored 80-plus percent on a physics benchmark, then insisted its calculations were right and the expert results were wrong. According to the post, a team checked and agreed with the model, bringing its score to 98%. The TheoPhysEval paper describes 50 unpublished research-level theoretical physics problems and says GPT-6-Astra in Codex averaged under $3 per problem.
