What the data says

Benchmarked on 20 of 27 tracked axes. Every figure below is the model's own published result on that board.

Strongest axes

  • 97.6 pct — LiveBench (78.1%)
  • 96.2 pct — LiveCodeBench (Artificial Analysis) (85.9%)

Weakest axes

  • 7 pct — Factuality Arena (1,368)
  • 9.5 pct — HHEM Hallucination (Vectara) (81.4%)
  • 14.6 pct — SimpleQA Verified (19.6%)

Uneven: 90.6 percentile points between its best and worst axis — 97.6 pct on LiveBench versus 7 pct on Factuality Arena.

Percentiles are the model's standing within each board's own population. Axes marked "not benchmarked" have no published result for this model — that is an absence of data, not a low score.
