Epoch AI / Knowledge · Graduate-level physics, chemistry and biology knowledge
What it measures, and how
Only Epoch's own re-run mean_score is used, retaining the reasoning tier and standard error. The 198 science knowledge questions require reasoning but do not represent all world knowledge.
How this evidence is used
Officially scored; the same question family shares a fixed budget.
