Closest models by score

Similar positions on shared benchmark leaderboards. Smaller gaps are closer.

14.6 percentile-point gap

18 of 30 shared benchmark comparisons

20.4 percentile-point gap

29 of 30 shared benchmark comparisons

How similarity is measured

Mean absolute gap in percentile positions on shared benchmark settings; lower is closer. At least 60% overlap is required, with a minimum of three when available. Independent evaluations are used when there are at least three; otherwise published report comparisons are used. Repeated model observations within one setting are averaged before ranking. Writing-style traits and composite indices are excluded. This describes similarity, not an overall quality ranking.

About the model report

Harnesses, task subsets, judges, hardware, and scoring transformations vary by benchmark. The launch footnotes are part of each result’s meaning. Reviewed 2026-10-25.

COMPARISON CHECKLIST

Match benchmark version, task subset, model effort, harness, tool access, attempt budget, scoring rule, and fallback behavior. A shared benchmark name is the start of a comparison, not proof that two reported scores use the same contract.
