Key points

  • GPT-6 Astra scored +80% on a Physics benchmark and insisted the expert results were wrong and its calculations were right.
  • A team checked and found GPT-6 Astra was correct; the new score is 98%.
  • @Kaju_Nut said the initial evaluation put GPT-6-Astra in the late eighties, followed closely by Opus 5.5, and that experts later found subtle errors in their own calculations.
  • @kimmonismus said TheoPhysEval's authors found errors in the reference solutions and confirmed Astra was correct, and that using Codex with tools and web access it scored 49/50 (98%).

Reaction on X: Replies largely welcome the result, one framing it as a shift from "shut up and calculate" to "slow down and think," and another joking that Astra graded the graders. One reply questions how models this good still fail to follow instructions in coding harnesses. The original poster did not respond.
