Where they disagree
The behaviors where the choice of model changes the answer.
The divergence index for this study is 19.6 points — the average distance between the most and least likely model across the coded behaviors. The gaps below are where which assistant an auto glass replacement buyer happens to ask matters most:
- Asks a clarifying question: from 0% (Gemini) to 73.3% (ChatGPT) — a 73-point spread.
- Recommends hiring a professional: from 33.3% (Gemini) to 93.3% (ChatGPT) — a 60-point spread.
- Gives selection criteria: from 26.7% (Gemini) to 53.3% (ChatGPT) — a 27-point spread.
- Tells the buyer to verify credentials: from 6.7% (Gemini) to 26.7% (ChatGPT) — a 20-point spread.
- Recommends multiple quotes: from 0% (Gemini) to 20% (ChatGPT) — a 20-point spread.
The widest single gap — asks a clarifying question, 73 points — means an auto glass replacement buyer can receive materially different guidance on the same question depending only on which assistant they happen to open, so any visibility strategy built on a single model's behavior describes only part of the auto glass replacement market.

Across 45 auto glass replacement answers, a specific provider was named in 13.3% of responses on average — roughly 0.3 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for auto glass replacement: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.

Each was put to all 3 models once, with identical wording, so the rates above describe how the assistants handled this exact auto glass replacement question set — not a general prior or a hand-picked subset.

How to read this
A note on the numbers.
A percentage here is the share of a model's 15 answers in which the behavior appeared at least once — not a confidence score. Because each model answered every question exactly once on 2026-07-05, the figures describe this specific auto glass replacement question set and snapshot rather than a general prior. The full protocol and coding rubric are documented in the study methodology.
Methodology
A controlled snapshot, documented end to end.
15 standardized buyer questions per industry, one response per model per question (ChatGPT (gpt-5-mini), Claude (claude-sonnet-5), Gemini (gemini-3-flash-preview)), collected 2026-07-05, coded against a fixed 12-behavior rubric with human QA.
