What is GPQA Diamond?
GPQA Diamond measures model accuracy on the 198 hardest graduate-level, Google-proof multiple-choice questions in physics, biology, and chemistry.

Tier S
The standard: frontier labs report it, or a trusted evaluator scores hundreds of models on it.
How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.
- 501 models scored
- in curated RL directories (2 pts)
On X · well regarded, moderate buzz, from 11 posts about GPQA Diamond in the last month
GPQA Diamond remains a standard reported metric in model and quant releases, though scores near 90%+ and a flawed question hint at saturation.
How we got to tier S
- Adoption: 501 models scored. Tier S.
- On X: well regarded, moderate buzz. “GPQA Diamond remains a standard reported metric in model and quant releases, though scores near 90%+ and a flawed question hint at saturation.” No move.
- In curated RL directories: 2 points, a floor of C.
- Confirmed: a line from its own site or paper places it.
A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
