Where they disagree

The behaviors where the choice of model changes the answer.

The divergence index for this study is 19.5 points — the average distance between the most and least likely model across the coded behaviors. The gaps below are where which assistant a mold removal companies buyer happens to ask matters most:

  • Asks a clarifying question: from 0% (Gemini) to 71.4% (ChatGPT) — a 71-point spread.
  • Recommends hiring a professional: from 42.9% (Gemini) to 85.7% (ChatGPT) — a 43-point spread.
  • Tells the buyer to verify credentials: from 14.3% (Gemini) to 45.7% (ChatGPT) — a 31-point spread.
  • Recommends multiple quotes: from 0% (Gemini) to 28.6% (ChatGPT) — a 29-point spread.
  • Gives selection criteria: from 25.7% (Gemini) to 51.4% (ChatGPT) — a 26-point spread.

The widest single gap — asks a clarifying question, 71 points — means a mold removal companies 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 mold removal companies market.

Where they agree

The points of near-consensus in Mold Removal Companies.

Trust signals

How well the models protect the mold removal companies buyer.

The single least-reproduced protective signal for mold removal companies is "tells the buyer to check reviews" at 9.5% on average — the clearest opening for content that supplies it, since the models are not yet reliably surfacing that guidance on their own.

Referral behavior

Do AI models name Mold Removal Companies providers?

For service providers the decisive question is whether these systems name anyone at all. Across 105 mold removal companies answers, a specific provider was named in 0% of responses on average — roughly 0 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for mold removal companies: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.

The question set

What these 35 Mold Removal Companies questions cover.

The 35 questions behind every percentage on this page were drawn from real mold removal companies (home services; buyer hiring decisions for this specific service) buyer journeys. Each was put to all 3 models once, with identical wording, so the rates above describe how the assistants handled this exact mold removal companies question set — not a general prior or a hand-picked subset. The full list is shown earlier on this page; the coded percentages are what those specific questions produced.

How to read this

A note on the numbers.

A percentage here is the share of a model's 35 answers in which the behavior appeared at least once — not a confidence score. Because each model answered every question exactly once on 2026-07-06, the figures describe this specific mold removal companies 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.

35 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 2026-07-06, coded against a fixed 12-behavior rubric with human QA.
