Repetition Consistency

The variance or stability of AI model responses when identical prompts are submitted across multiple independent API calls.

Detailed Definition

AI models generate text stochastically (governed by temperature and top-p sampling). Repetition Consistency evaluates whether a brand is recommended every single time a prompt is asked or only sporadically.

Formula / Calculation StandardConsistency (%) = (Identical Mention Outcomes / Total Repetition Cycles) × 100
Why It Matters for Brands

A brand that appears 10 out of 10 times has high consumer reliability, whereas a brand that appears only 2 out of 10 times suffers from prompt variance.

How Fameproof Measures It

Fameproof runs a minimum of 2 repetition cycles per prompt/model pairing to calculate variance and 95% confidence intervals.
