What the data says

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

Weakest axes

  • 6.3 pct — SWE-bench Verified (48.5%)
  • 13.5 pct — ARC-AGI-2 (0.4%)

Uneven: 74.7 percentile points between its best and worst axis — 81 pct on HHEM Hallucination (Vectara) versus 6.3 pct on SWE-bench Verified.

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.
