What the data says

Benchmarked on 4 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%)
  • 98.6 pct — FrontierMath (51.7%)
  • 96.9 pct — SWE-bench Verified (80.6%)

Uneven: 4.5 percentile points between its best and worst axis — 100 pct on AIME (math) versus 95.5 pct on GPQA Diamond.

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.

  • gpt-5.5-pre-release stands at 77.3 (raw mean 97.7) — measured on 4 of 27 axes.
