By model

How each assistant handled Glass Manufacturers questions.

Reading the 117 answers model by model shows how differently the three assistants treat the same glass manufacturers questions. On the most consequential behavior — whether to send the buyer to a professional at all — the rate ranged from 53.8% (ChatGPT) down to 23.1% (Gemini), a 31-point gap on an identical question set.

Across the 39 glass manufacturers answers it produced, ChatGPT recommended hiring a professional in 53.8% of them and suggested a DIY approach first 15.4% of the time. It named a specific provider in 17.9% of answers (about 0.8 distinct providers per answer) and included price or cost information 15.4% of the time. ChatGPT asked a clarifying question before answering in 59% of cases, warned about red flags or scams in 5.1%, and told the buyer to verify credentials in 28.2%, averaging 635 words per answer. On the remaining cues it told the buyer to check reviews in 2.6%, pointed to case studies or a portfolio in 7.7%, and framed the choice around local proximity in 41%; a selection-criteria checklist appeared in 59% of its answers and a recommendation to gather multiple quotes in 23.1%.

Across the 39 glass manufacturers answers it produced, Claude recommended hiring a professional in 46.2% of them and suggested a DIY approach first 5.1% of the time. It named a specific provider in 23.1% of answers (about 1.5 distinct providers per answer) and included price or cost information 12.8% of the time. Claude asked a clarifying question before answering in 66.7% of cases, warned about red flags or scams in 7.7%, and told the buyer to verify credentials in 28.2%, averaging 315 words per answer. On the remaining cues it told the buyer to check reviews in 0%, pointed to case studies or a portfolio in 5.1%, and framed the choice around local proximity in 25.6%; a selection-criteria checklist appeared in 66.7% of its answers and a recommendation to gather multiple quotes in 20.5%.

Across the 39 glass manufacturers answers it produced, Gemini recommended hiring a professional in 23.1% of them and suggested a DIY approach first 7.7% of the time. It named a specific provider in 23.1% of answers (about 0.7 distinct providers per answer) and included price or cost information 15.4% of the time. Gemini asked a clarifying question before answering in 0% of cases, warned about red flags or scams in 2.6%, and told the buyer to verify credentials in 15.4%, averaging 242 words per answer. On the remaining cues it told the buyer to check reviews in 0%, pointed to case studies or a portfolio in 5.1%, and framed the choice around local proximity in 17.9%; a selection-criteria checklist appeared in 35.9% of its answers and a recommendation to gather multiple quotes in 0%.

Taken together, ChatGPT is the assistant most likely to route a glass manufacturers buyer to a professional (53.8%) and Gemini the least (23.1%). ChatGPT produced the longest answers, at 635 words on average. Specific providers were named most often by Claude (23.1%) — even there, roughly one answer in 4 carried a name.

Where they disagree

The behaviors where the choice of model changes the answer.

The divergence index for this study is 22.2 points — the average distance between the most and least likely model across the coded behaviors. The gaps below are where which assistant a glass manufacturers buyer happens to ask matters most:

  • Asks a clarifying question: from 0% (Gemini) to 66.7% (Claude) — a 67-point spread.
  • Gives selection criteria: from 35.9% (Gemini) to 66.7% (Claude) — a 31-point spread.
  • Recommends hiring a professional: from 23.1% (Gemini) to 53.8% (ChatGPT) — a 31-point spread.
  • Mentions local proximity: from 17.9% (Gemini) to 41% (ChatGPT) — a 23-point spread.
  • Recommends multiple quotes: from 0% (Gemini) to 23.1% (ChatGPT) — a 23-point spread.

The widest single gap — asks a clarifying question, 67 points — means a glass manufacturers 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 glass manufacturers market.

Where they agree

The points of near-consensus in Glass Manufacturers.

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

  • Gives price or cost information: 12.8%–15.4% across all three (a 3-point spread).
  • Tells the buyer to check reviews: 0%–2.6% across all three (a 3-point spread).
  • Mentions case studies or portfolio: 5.1%–7.7% across all three (a 3-point spread).
  • Warns about red flags or scams: 2.6%–7.7% across all three (a 5-point spread).

Measured question by question, the three assistants coded a response the same way most consistently on "tells the buyer to check reviews" (identical coding in 97.4% of questions) and least consistently on "asks a clarifying question" (12.8%).

Every behavior, measured

All twelve coded behaviors for Glass Manufacturers, averaged across the three models.

The behaviors AI models reproduce most often for glass manufacturers are gives selection criteria (53.9% on average), asks a clarifying question (41.9%) and recommends hiring a professional (41%); the rarest are tells the buyer to check reviews (0.9%), warns about red flags or scams (5.1%) and mentions case studies or portfolio (6%). Each figure below is the share of a model's 39 answers in which the behavior appeared at least once, averaged across the 3 models with the full per-model range in parentheses:

  • Gives selection criteria: 53.9% on average (ChatGPT 59%, Claude 66.7%, Gemini 35.9%) — a 31-point spread.
  • Asks a clarifying question: 41.9% on average (ChatGPT 59%, Claude 66.7%, Gemini 0%) — a 67-point spread.

Trust signals

How well the models protect the glass manufacturers buyer.

Beyond whether to hire, the rubric codes how carefully each assistant protects the glass manufacturers buyer once a decision is made. Telling the buyer to check reviews or ratings appeared in 0.9% of answers on average. Verifying credentials or certifications appeared in 23.9%. Warning about red flags or scams appeared in 5.1%.

On structuring the decision, a selection-criteria checklist showed up in 53.9% of answers on average and a recommendation to gather multiple quotes in 14.5%. The single least-reproduced protective signal for glass manufacturers is "tells the buyer to check reviews" at 0.9% 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 Glass Manufacturers providers?

For service providers the decisive question is whether these systems name anyone at all. Across 117 glass manufacturers answers, a specific provider was named in 21.4% of responses on average — roughly 1 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for glass manufacturers: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.

The question set

What these 39 Glass Manufacturers questions cover.

The 39 questions behind every percentage on this page were drawn from real glass manufacturers (manufacturing / industrial B2B; 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 glass manufacturers 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 39 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 glass manufacturers question set and snapshot rather than a general prior. The full protocol and coding rubric are documented in the study methodology.
