Top 200,000 authority brands extracted from Gemini 4 Hydrogen's parametric memory

Gemini 4 Hydrogen became the default model in Google's AI Mode on 12 November 2026, and it answers the hardest questions in AI Overviews. Google calls it the biggest model upgrade to Search yet. This page shows what that model remembers about brands on its own, before it searches the web: which brands it knows, how much authority each one holds, and which brands it ties together.

What this is

An AI model learns about brands from the text it is trained on. What it keeps is called its parametric memory: everything it can recall without looking anything up.

We extracted the brand part of that memory from Gemini 4 Hydrogen. The result is a network of 239,266 brands and the links the model makes between them.

Each brand gets an authority score from 0 to 100. A brand scores high when many brands lead to it, and when those brands score high themselves. It is the same idea Google's PageRank uses for web pages, applied to the model's memory.

Every brand has two kinds of authority: one across all brands, and one inside each of 74 industries.

How it was done

We asked the model three kinds of question, 52,923 times in total, and kept every answer.

  1. Name brands

    1,105 times with no topic. The answers show which brands come to the model first.

    name 100 brands, one per line, say nothing else
  2. Name brands for an industry

    7,406 times, 100 for each of 74 industries, from airlines to water utilities.

    name 100 brands that you associate with the following industry, one per line, say nothing else industry: Beverages
  3. Name the brands tied to each brand

    44,412 times: once for every brand from steps 1 and 2, and once more inside each of its industries.

    name 100 brands most closely associated with the following brand, ordered from most to least associated, one per line, say nothing else brand: Coca-Cola name 100 brands most closely associated with the following brand in the following industry, ordered from most to least associated, one per line, say nothing else brand: Coca-Cola industry: Beverages

Every answer in step 3 is a list of links from one brand to others, strongest first. The authority score comes from those links.
