Seedance 2.0 Fast: Blind output test, row by row

How this is scored

The same prompts for every model, scored by judges from different model makers who don’t see the model name.

68.6/ 1000.2941 × 71.4 + 0.2941 × 71 + 0.2353 × 62.8 + 0.1765 × 67.6 = 68.6 / 100

3 judges from different model makers · run Sep 28, 2026

Agreement with public human-vote leaderboards is low for video models (Spearman rank correlation 0.23 across 21 models, below 0.60), so the blind test counts at a reduced weight in the Index.

How this is scored

The family score is the average of its task scores, so a single cautious task pulls the whole family down. Here is where every point came from.

Each level is worth 20 points: 20 × pass rate × confidence. One run gives 60% confidence, two give 80%, three or more give 100%. Untested levels score zero. Each task is tested on its own, and the family score is their average.
