The Best LLMs on GPQA Diamond
Which model answers the most graduate-level science questions?
86 of the 152 buyable models publish a GPQA Diamond score. It measures graduate-level reasoning, not coding, so it is reported here on its own and nowhere folded into a composite.
Method: Published GPQA Diamond score, descending, exactly as reported. GPQA Diamond is a graduate-level science question set, so it measures reasoning rather than software work, and it is never mixed into the coding quality score. Pricing as of October 2026. 22 rows below carry a score measured at a non-default reasoning tier and are marked as such; every affected model is named on the hub. Read the full method.
