Each cell is the brand’s average position in that AI model’s answers across the month's capture; indigo marks each AI model’s top answer among the brands shown. A dash means that AI model never named the brand. A model’s own list can be longer than this board, so a position can exceed the number of brands ranked here.
How this ranking is built
Every month, each of the 9 leading AI models (ChatGPT, Claude and Gemini among them) is asked the question a buyer asks, once:
“What are the best smart thermostats? Recommend the specific models people actually buy — exact model names, not just brands.”
Specific models are then ranked by their AI Recommendation Score: how many AI models recommend them and how often they come up. The brand band above sums each maker’s presence. Presence in real answers is the only input. Read the full methodology →
