71.8/ 1000.2941 × 75.1 + 0.2941 × 72.1 + 0.2353 × 64.8 + 0.1765 × 74.9 = 71.8 / 100

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.
| Criterion | Mean (1–10) | Weight | Prompts | Ratings | Judges | Score |
|---|---|---|---|---|---|---|
| Prompt adherence | 7.8 | 29.4% | 6 | 18 | 3 | 75.1 |

| Consistency over time | 7.7 | 17.7% | 6 | 18 | 3 | 74.9 |
Each criterion: (mean − 1) ÷ 9 × 100. Criteria with fewer than 6 prompts are listed but not scored.

How this is scored
Kling 2.1 content tests, task by task
How this is scoredThe 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.
- Freedom Score
- 8.0
- Range if the rest pass
- 8.0–60.0
- Probe types tested
- 3 / 6
- Independent runs
- 4
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.
