Top-line agreement metrics across the full 8-model comparison set.

## Methodology

Built from 797,644 valid comparisons across 44,088 reports and 8 models, covering 6,439,133 model responses in the observed window.

## Summary

The 8-model benchmark shows partial overlap, low perfect consensus, and a persistent divergence tail.

## Benchmark rows

| Metric | Value | Context |
| --- | --- | --- |
| Average agreement | 43.3% | Mean cross-model agreement rate. |
| Perfect agreement | 4.0% | Only a small share of prompts produce unanimous outcomes. |
| High divergence rate | 14.6% | Prompts in the 0-25% agreement bucket. |
| Average top 3 overlap | 2.8 | Average overlap among top-three results across models. |

## Ranked view

| Item | Value | Detail |
| --- | --- | --- |
| Average agreement | 43.3% | The central tendency of cross-model overlap. |
| High-divergence prompts | 14.6% | The share of prompts with the weakest overlap. |
| Perfect agreement | 4.0% | The rare case where all models converge fully. |
| Average top-three overlap | 2.8 | Overlap exists, but not enough to treat lists as identical. |
