# Share of Model

Canonical: https://seangarschi.com/glossary/share-of-model

**How often an AI names you versus your competitors.**

Share of model is the percentage of relevant AI-generated answers in which a brand is mentioned, measured across a fixed prompt set. It is the generative-search analogue of share of voice, and the closest thing GEO has to a headline metric.

It is measured, not reported by any platform. You run the prompts, count the mentions, and divide. The number is noisy in absolute terms and useful in trend.
