By model

How each assistant handled Luxury Brands questions.

Reading the 45 answers model by model shows how differently the three assistants treat the same luxury brands questions. On the most consequential behavior — whether to send the buyer to a professional at all — the rate ranged from 66.7% (ChatGPT) down to 46.7% (Claude), a 20-point gap on an identical question set.

Across the 15 luxury brands answers it produced, ChatGPT recommended hiring a professional in 66.7% of them and suggested a DIY approach first 40% of the time. It named a specific provider in 33.3% of answers (about 0.8 distinct providers per answer) and included price or cost information 20% of the time. ChatGPT asked a clarifying question before answering in 46.7% of cases, warned about red flags or scams in 33.3%, and told the buyer to verify credentials in 20%, averaging 621 words per answer. On the remaining cues it told the buyer to check reviews in 20%, pointed to case studies or a portfolio in 13.3%, and framed the choice around local proximity in 33.3%; a selection-criteria checklist appeared in 53.3% of its answers and a recommendation to gather multiple quotes in 6.7%.

Across the 15 luxury brands answers it produced, Claude recommended hiring a professional in 46.7% of them and suggested a DIY approach first 40% of the time. It named a specific provider in 73.3% of answers (about 3.1 distinct providers per answer) and included price or cost information 33.3% of the time. Claude asked a clarifying question before answering in 60% of cases, warned about red flags or scams in 33.3%, and told the buyer to verify credentials in 33.3%, averaging 295 words per answer. On the remaining cues it told the buyer to check reviews in 20%, pointed to case studies or a portfolio in 0%, and framed the choice around local proximity in 13.3%; a selection-criteria checklist appeared in 46.7% of its answers and a recommendation to gather multiple quotes in 6.7%.

Across the 15 luxury brands answers it produced, Gemini recommended hiring a professional in 46.7% of them and suggested a DIY approach first 6.7% of the time. It named a specific provider in 53.3% of answers (about 1.5 distinct providers per answer) and included price or cost information 40% of the time. Gemini asked a clarifying question before answering in 0% of cases, warned about red flags or scams in 6.7%, and told the buyer to verify credentials in 13.3%, averaging 206 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 6.7%; a selection-criteria checklist appeared in 20% of its answers and a recommendation to gather multiple quotes in 0%.

Taken together, ChatGPT is the assistant most likely to route a luxury brands buyer to a professional (66.7%) and Claude the least (46.7%). ChatGPT produced the longest answers, at 621 words on average. Specific providers were named most often by Claude (73.3%) — even there, roughly one answer in 1 carried a name.

Where they disagree

The behaviors where the choice of model changes the answer.

The divergence index for this study is 28.1 points — the average distance between the most and least likely model across the coded behaviors. The gaps below are where which assistant a luxury brands buyer happens to ask matters most:

  • Asks a clarifying question: from 0% (Gemini) to 60% (Claude) — a 60-point spread.
  • Names a specific provider: from 33.3% (ChatGPT) to 73.3% (Claude) — a 40-point spread.
  • Suggests a DIY approach first: from 6.7% (Gemini) to 40% (ChatGPT) — a 33-point spread.
  • Gives selection criteria: from 20% (Gemini) to 53.3% (ChatGPT) — a 33-point spread.
  • Mentions local proximity: from 6.7% (Gemini) to 33.3% (ChatGPT) — a 27-point spread.

The widest single gap — asks a clarifying question, 60 points — means a luxury brands 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 luxury brands market.

Where they agree

The points of near-consensus in Luxury Brands.

On other behaviors the three models move almost in lockstep — the points of near-consensus for luxury brands, where all three landed within a few points of each other:

  • Recommends multiple quotes: 0%–6.7% across all three (a 7-point spread).
  • Tells the buyer to check reviews: 6.7%–20% across all three (a 13-point spread).
  • Mentions case studies or portfolio: 0%–13.3% across all three (a 13-point spread).
  • Recommends hiring a professional: 46.7%–66.7% across all three (a 20-point spread).

Measured question by question, the three assistants coded a response the same way most consistently on "recommends multiple quotes" (identical coding in 93.3% of questions) and least consistently on "asks a clarifying question" (20%).

Every behavior, measured

All twelve coded behaviors for Luxury Brands, averaged across the three models.

The behaviors AI models reproduce most often for luxury brands are recommends hiring a professional (53.4% on average), names a specific provider (53.3%) and gives selection criteria (40%); the rarest are mentions case studies or portfolio (4.4%), recommends multiple quotes (4.5%) and tells the buyer to check reviews (15.6%). 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: 53.4% on average (ChatGPT 66.7%, Claude 46.7%, Gemini 46.7%) — a 20-point spread.
  • Names a specific provider: 53.3% on average (ChatGPT 33.3%, Claude 73.3%, Gemini 53.3%) — a 40-point spread.
  • Gives selection criteria: 40% on average (ChatGPT 53.3%, Claude 46.7%, Gemini 20%) — a 33-point spread.
  • Asks a clarifying question: 35.6% on average (ChatGPT 46.7%, Claude 60%, Gemini 0%) — a 60-point spread.
  • Gives price or cost information: 31.1% on average (ChatGPT 20%, Claude 33.3%, Gemini 40%) — a 20-point spread.

  • Mentions local proximity: 17.8% on average (ChatGPT 33.3%, Claude 13.3%, Gemini 6.7%) — a 27-point spread.
  • Tells the buyer to check reviews: 15.6% on average (ChatGPT 20%, Claude 20%, Gemini 6.7%) — a 13-point spread.
  • Recommends multiple quotes: 4.5% on average (ChatGPT 6.7%, Claude 6.7%, Gemini 0%) — a 7-point spread.
  • Mentions case studies or portfolio: 4.4% on average (ChatGPT 13.3%, Claude 0%, Gemini 0%) — a 13-point spread.

Trust signals

How well the models protect the luxury brands buyer.

Beyond whether to hire, the rubric codes how carefully each assistant protects the luxury brands buyer once a decision is made. Telling the buyer to check reviews or ratings appeared in 15.6% of answers on average. Verifying credentials or certifications appeared in 22.2%. Warning about red flags or scams appeared in 24.4%.

On structuring the decision, a selection-criteria checklist showed up in 40% of answers on average and a recommendation to gather multiple quotes in 4.5%. The single least-reproduced protective signal for luxury brands is "recommends multiple quotes" at 4.5% 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 Luxury Brands providers?

For service providers the decisive question is whether these systems name anyone at all. Across 45 luxury brands answers, a specific provider was named in 53.3% of responses on average — roughly 1.8 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for luxury brands: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.

The question set

What these 15 Luxury Brands questions cover.

The 15 questions behind every percentage on this page were drawn from real luxury brands (ecommerce / online retail; 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 luxury brands 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 2026-07-05, the figures describe this specific luxury brands 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.
