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
- 94.3 pct — LiveCodeBench (Artificial Analysis) (83.8%)
- 91.4 pct — IFBench (Artificial Analysis) (75.4%)
- 86.1 pct — MMLU-Pro (Artificial Analysis) (83.7%)
Uneven: 79.2 percentile points between its best and worst axis — 94.3 pct on LiveCodeBench (Artificial Analysis) versus 15.1 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.
