A model × benchmark leaderboard: every column normalised in its own direction, cells shaded with the raw score printed, per-column bests marked, rank with movement arrows against the previous snapshot, and a weighted index whose whole-percent weights always total 100.

Index weights
Frontier eval board: 8 models scored on 6 benchmarks, one column per benchmark, shaded by each column's normalised score with the raw number printed. Kestrel 3 Large leads the index at 76.5, 0.5 ahead of Meridian 2.5 Pro. 3 of 8 models hold the 6 column bests. Index = the weighted mean of each included benchmark's normalised score, printed 0–100. The whole-percent weights above are apportioned by largest remainder and total 100% across the 6 benchmarks in it. TTFT and Price ship no declared range, so 2 of 6 columns are normalised against this board's own spread — the best model there normalises to 100 by construction, however close the field is. Rank is by index, not by the sort — reorder the board by any column and the ranking stays put. The arrow is the move against the 2026-08-10 board: 2 up, 3 down, 3 held. † Nimbus Air 3 (5 of 6) is scored over the benchmarks it reports, with those weights rescaled to total 100 among them.
