What the data says

Benchmarked on 14 of 27 tracked axes. Every figure below is the model's own published result on that board.

Strongest axes

  • 100 pct — AIME (math) (100.0%)
  • 98.9 pct — ARC-AGI-2 (94.2%)
  • 98.6 pct — GPQA Diamond (95.4%)

Uneven: 19.2 percentile points between its best and worst axis — 100 pct on AIME (math) versus 80.8 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.
