By model
How each assistant handled Construction questions.
Reading the 45 answers model by model shows how differently the three assistants treat the same construction questions. On the most consequential behavior — whether to send the buyer to a professional at all — the rate ranged from 80% (ChatGPT) down to 53.3% (Gemini), a 27-point gap on an identical question set.
Across the 15 construction answers it produced, ChatGPT recommended hiring a professional in 80% of them and suggested a DIY approach first 20% of the time. It named a specific provider in 0% of answers (about 0 distinct providers per answer) and included price or cost information 26.7% of the time. ChatGPT asked a clarifying question before answering in 66.7% of cases, warned about red flags or scams in 26.7%, and told the buyer to verify credentials in 26.7%, averaging 598 words per answer. On the remaining cues it told the buyer to check reviews in 13.3%, pointed to case studies or a portfolio in 6.7%, and framed the choice around local proximity in 33.3%; a selection-criteria checklist appeared in 33.3% of its answers and a recommendation to gather multiple quotes in 26.7%.
Across the 15 construction answers it produced, Claude recommended hiring a professional in 60% of them and suggested a DIY approach first 20% of the time. It named a specific provider in 0% of answers (about 0 distinct providers per answer) and included price or cost information 60% of the time. Claude asked a clarifying question before answering in 73.3% of cases, warned about red flags or scams in 26.7%, and told the buyer to verify credentials in 13.3%, averaging 305 words per answer. On the remaining cues it told the buyer to check reviews in 13.3%, pointed to case studies or a portfolio in 0%, and framed the choice around local proximity in 26.7%; a selection-criteria checklist appeared in 26.7% of its answers and a recommendation to gather multiple quotes in 13.3%.
Across the 15 construction answers it produced, Gemini recommended hiring a professional in 53.3% of them and suggested a DIY approach first 13.3% of the time. It named a specific provider in 6.7% of answers (about 0.2 distinct providers per answer) and included price or cost information 46.7% of the time. Gemini asked a clarifying question before answering in 0% of cases, warned about red flags or scams in 20%, and told the buyer to verify credentials in 6.7%, averaging 253 words per answer. On the remaining cues it told the buyer to check reviews in 6.7%, pointed to case studies or a portfolio in 0%, and framed the choice around local proximity in 20%; a selection-criteria checklist appeared in 26.7% of its answers and a recommendation to gather multiple quotes in 0%.
Taken together, ChatGPT is the assistant most likely to route a construction buyer to a professional (80%) and Gemini the least (53.3%). ChatGPT produced the longest answers, at 598 words on average. Specific providers were named most often by Gemini (6.7%) — even there, roughly one answer in 15 carried a name.
Where they disagree
The behaviors where the choice of model changes the answer.
Question-level model disagreement is 20.7% — the average pairwise rate at which models received different binary codes across questions and behaviors. The observed rate spreads below are a separate measure showing where which assistant a construction buyer happens to ask matters most:
- Asks a clarifying question: from 0% (Gemini) to 73.3% (Claude) — a 73-point spread.
- Gives price or cost information: from 26.7% (ChatGPT) to 60% (Claude) — a 33-point spread.
- Recommends hiring a professional: from 53.3% (Gemini) to 80% (ChatGPT) — a 27-point spread.
- Recommends multiple quotes: from 0% (Gemini) to 26.7% (ChatGPT) — a 27-point spread.
- Tells the buyer to verify credentials: from 6.7% (Gemini) to 26.7% (ChatGPT) — a 20-point spread.
The widest single gap — asks a clarifying question, 73 points — means a construction 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 construction market.
Where they agree
The points of near-consensus in Construction.
On other behaviors the three models move almost in lockstep — the points of near-consensus for construction, where all three landed within a few points of each other:
- Tells the buyer to check reviews: 6.7%–13.3% across all three (a 7-point spread).
- Gives selection criteria: 26.7%–33.3% across all three (a 7-point spread).
- Suggests a DIY approach first: 13.3%–20% across all three (a 7-point spread).
- Names a specific provider: 0%–6.7% across all three (a 7-point spread).
Measured question by question, the three assistants coded a response the same way most consistently on "names a specific provider" (identical coding in 93.3% of questions) and least consistently on "asks a clarifying question" (20%).
Every behavior, measured
All twelve coded behaviors for Construction, averaged across the three models.
The behaviors AI models reproduce most often for construction are recommends hiring a professional (64.4% on average), asks a clarifying question (46.7%) and gives price or cost information (44.5%); the rarest are mentions case studies or portfolio (2.2%), names a specific provider (2.2%) and tells the buyer to check reviews (11.1%). Each figure below is the share of a model's 15 answers in which the behavior appeared at least once, averaged across the 3 models with the full per-model range in parentheses:
- Recommends hiring a professional: 64.4% on average (ChatGPT 80%, Claude 60%, Gemini 53.3%) — a 27-point spread.
- Asks a clarifying question: 46.7% on average (ChatGPT 66.7%, Claude 73.3%, Gemini 0%) — a 73-point spread.

Trust signals
How well the models protect the construction buyer.
Beyond whether to hire, the rubric codes how carefully each assistant protects the construction buyer once a decision is made. Telling the buyer to check reviews or ratings appeared in 11.1% of answers on average. Verifying credentials or certifications appeared in 15.6%. Warning about red flags or scams appeared in 24.5%.
On structuring the decision, a selection-criteria checklist showed up in 28.9% of answers on average and a recommendation to gather multiple quotes in 13.3%. The single least-reproduced protective signal for construction is "tells the buyer to check reviews" at 11.1% 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 Construction providers?
For service providers the decisive question is whether these systems name anyone at all. Across 45 construction answers, a specific provider was named in 2.2% of responses on average — roughly 0.1 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for construction: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.
The question set
What these 15 Construction questions cover.
The 15 questions behind every percentage on this page form a frozen construction (home services; buyer hiring decisions for this specific service) buyer-intent benchmark. Each was put to all 3 models once, with identical wording, so the rates above describe how the assistants handled this exact construction 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 15 answers in which the behavior appeared at least once — not a confidence score. Because each model answered every question exactly once on 2026-07-04, the figures describe this specific construction 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 frozen benchmark questions, one expected response per model per question (ChatGPT API (gpt-5-mini), Claude API (claude-sonnet-5), Gemini API (gemini-3-flash-preview)), collected 2026-07-04 and coded against a fixed 12-behavior rubric. The pipeline validates the schema, recomputes aggregates and reports consistency issues. AI outputs vary with model version, location and time, so the figures describe this edition's exact sample and measurement window. Read the full methodology →
