Thin coverage — read with caution
This model appears on only 2 of 27 benchmark axes considered. The overall standing has been shrunk toward the neutral 50 to reflect the small sample, and no weaknesses have been claimed — a low percentile on 2 axes is a coverage artifact, not a measured weakness.
What the data says
Benchmarked on 2 of 27 tracked axes. Every figure below is the model's own published result on that board.
On only 2 board(s), a ranked list of strengths would be false authority — the per-axis figures are shown below instead, without a verdict.
Uneven: 16.5 percentile points between its best and worst axis — 94.7 pct on WebDev Arena versus 78.2 pct on Agent 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.
