How are these rankings measured?
We ask each model the same buying questions every week (1,520 queries this period), record the full answers, and score each named brand 0-100 by how early and how consistently it appears. Every question runs through the official model APIs, with web search on, not through the consumer chat apps, so nothing is personalized to a user. Each model is scored independently; the consensus blends all 4.
Do the AI models agree with each other?
At the top, yes. Every model crowns the same #1 this week. Further down the board they diverge, which is why each brand carries a spread figure: the gap between its best and worst model rank.
