What the data says

Benchmarked on 5 of 27 tracked axes. Every figure below is the model's own published result on that board.

Weakest axes

  • 4.1 pct — Factuality Arena (1,343)

Uneven: 38.9 percentile points between its best and worst axis — 43 pct on Coding versus 4.1 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.
