GPI™ (Generative Presence Index)
One headline index for how strongly your brand shows up across generative surfaces.
Use it alongside LLM-Score and Share of Voice for a full picture.
Definition
GPI™ (Generative Presence Index) is Getllmspy’s umbrella index that compresses mention rate, factual correctness, sentiment, and breadth of model coverage into a single comparable figure. It is designed for leadership dashboards where you need one trend line, not a wall of charts. GPI rewards consistent presence across models, not a single viral answer in one chat UI.
How it's computed
Inputs mirror the report pipeline: answers from your prompt pack, scored for presence, accuracy, and tone, then weighted across models using traffic and freshness assumptions. Coverage matters: missing YandexGPT or GigaChat when you sell in CIS would lower GPI even if ChatGPT looks perfect. The exact weighting may evolve as models shift; snapshots stay comparable week to week within the same product version.
How to read it
Treat GPI like a credit score for LLM visibility: direction matters more than debating ten points with your agency. Rising GPI after a schema or content push validates the work. A flat GPI with rising Share of Voice but falling LLM-Score means you are loud but wrong—fix facts before you scale mentions.
GPI™ (Generative Presence Index) vs LLM-Score
LLM-Score is the core 0–100 quality/presence blend for scripted checks. GPI is the higher-level index meant for portfolio views across models and markets.
When to use
