Comparison prompts are the most stable query class
Comparison prompts average 50.4% agreement, representing the highest stability among tracked query classes.
The study 'Same Question, Different AI, Different Answers' evaluated response stability across multiple AI models and identified comparison prompts as the most consistent query class.
The numbers behind it.
- Comparison-query agreement
- Comparison prompts produce the highest average agreement.
- 50.4%
The evidence.
| Measure | Result |
|---|---|
| Comparison-query agreement Comparison prompts produce the highest average agreement. | 50.4% |
Population and method
Built from 797,644 valid comparisons across 44,088 reports and 8 models, covering 6,439,133 model responses in the observed window.
Where the evidence stops
Agreement is measured across recommendation outputs, not across hidden reasoning or retrieval context.
Average agreement can hide large differences between query classes and model pairs.
The study measures overlap, not which answer was objectively “right”.
What to do with this
Strategists and operators should prioritize comparison pages to anchor more portable visibility across AI platforms, as these formats offer greater consistency than broader recommendation content.
