Model by model
15-point average divergence: which AI you ask changes the answer.
The divergence index is the average gap between the most and least likely model per behavior. Higher = the models disagree more about fertility buyers.

By model
How each assistant handled Fertility questions.
Reading the 120 answers model by model shows how differently the three assistants treat the same fertility questions. On the most consequential behavior — whether to send the buyer to a professional at all — the rate ranged from 62.5% (ChatGPT) down to 22.5% (Gemini), a 40-point gap on an identical question set.
Across the 40 fertility answers it produced, ChatGPT recommended hiring a professional in 62.5% of them and suggested a DIY approach first 12.5% of the time. It named a specific provider in 2.5% of answers (about 0.2 distinct providers per answer) and included price or cost information 7.5% of the time. ChatGPT asked a clarifying question before answering in 65% of cases, warned about red flags or scams in 7.5%, and told the buyer to verify credentials in 12.5%, averaging 568 words per answer. On the remaining cues it told the buyer to check reviews in 10%, pointed to case studies or a portfolio in 0%, and framed the choice around local proximity in 27.5%; a selection-criteria checklist appeared in 27.5% of its answers and a recommendation to gather multiple quotes in 12.5%.
Across the 40 fertility answers it produced, Claude recommended hiring a professional in 45% of them and suggested a DIY approach first 2.5% of the time. It named a specific provider in 7.5% of answers (about 0.2 distinct providers per answer) and included price or cost information 7.5% of the time. Claude asked a clarifying question before answering in 67.5% of cases, warned about red flags or scams in 12.5%, and told the buyer to verify credentials in 10%, averaging 301 words per answer. On the remaining cues it told the buyer to check reviews in 15%, pointed to case studies or a portfolio in 0%, and framed the choice around local proximity in 17.5%; a selection-criteria checklist appeared in 25% of its answers and a recommendation to gather multiple quotes in 5%.
Across the 40 fertility answers it produced, Gemini recommended hiring a professional in 22.5% of them and suggested a DIY approach first 7.5% of the time. It named a specific provider in 10% of answers (about 0.4 distinct providers per answer) and included price or cost information 15% of the time. Gemini asked a clarifying question before answering in 2.5% of cases, warned about red flags or scams in 7.5%, and told the buyer to verify credentials in 7.5%, averaging 261 words per answer. On the remaining cues it told the buyer to check reviews in 5%, pointed to case studies or a portfolio in 0%, and framed the choice around local proximity in 7.5%; 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 fertility buyer to a professional (62.5%) and Gemini the least (22.5%). ChatGPT produced the longest answers, at 568 words on average. Specific providers were named most often by Gemini (10%) — even there, roughly one answer in 10 carried a name.
Where they disagree
The behaviors where the choice of model changes the answer.
The divergence index for this study is 15.3 points — the average distance between the most and least likely model across the coded behaviors. The gaps below are where which assistant a fertility buyer happens to ask matters most:
- Asks a clarifying question: from 2.5% (Gemini) to 67.5% (Claude) — a 65-point spread.
- Recommends hiring a professional: from 22.5% (Gemini) to 62.5% (ChatGPT) — a 40-point spread.
- Mentions local proximity: from 7.5% (Gemini) to 27.5% (ChatGPT) — a 20-point spread.
- Recommends multiple quotes: from 0% (Gemini) to 12.5% (ChatGPT) — a 13-point spread.
- Suggests a DIY approach first: from 2.5% (Claude) to 12.5% (ChatGPT) — a 10-point spread.
The widest single gap — asks a clarifying question, 65 points — means a fertility 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 fertility market.
Where they agree
The points of near-consensus in Fertility.
On other behaviors the three models move almost in lockstep — the points of near-consensus for fertility, where all three landed within a few points of each other:
- Mentions case studies or portfolio: 0% across all three models.
- Tells the buyer to verify credentials: 7.5%–12.5% across all three (a 5-point spread).
- Warns about red flags or scams: 7.5%–12.5% across all three (a 5-point spread).
- Names a specific provider: 2.5%–10% across all three (a 8-point spread).
Measured question by question, the three assistants coded a response the same way most consistently on "mentions case studies or portfolio" (identical coding in 100% of questions) and least consistently on "asks a clarifying question" (15%).
Every behavior, measured
All twelve coded behaviors for Fertility, averaged across the three models.
The behaviors AI models reproduce most often for fertility are asks a clarifying question (45% on average), recommends hiring a professional (43.3%) and gives selection criteria (24.2%); the rarest are mentions case studies or portfolio (0%), recommends multiple quotes (5.8%) and names a specific provider (6.7%). Each figure below is the share of a model's 40 answers in which the behavior appeared at least once, averaged across the 3 models with the full per-model range in parentheses:
- Asks a clarifying question: 45% on average (ChatGPT 65%, Claude 67.5%, Gemini 2.5%) — a 65-point spread.

- Recommends multiple quotes: 5.8% on average (ChatGPT 12.5%, Claude 5%, Gemini 0%) — a 13-point spread.
- Mentions case studies or portfolio: 0% on average (ChatGPT 0%, Claude 0%, Gemini 0%).
Trust signals
How well the models protect the fertility buyer.
Beyond whether to hire, the rubric codes how carefully each assistant protects the fertility buyer once a decision is made. Telling the buyer to check reviews or ratings appeared in 10% of answers on average. Verifying credentials or certifications appeared in 10%. Warning about red flags or scams appeared in 9.2%.
On structuring the decision, a selection-criteria checklist showed up in 24.2% of answers on average and a recommendation to gather multiple quotes in 5.8%. The single least-reproduced protective signal for fertility is "recommends multiple quotes" at 5.8% 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 Fertility providers?
For service providers the decisive question is whether these systems name anyone at all. Across 120 fertility answers, a specific provider was named in 6.7% 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 fertility: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.
The question set
What these 40 Fertility questions cover.
The 40 questions behind every percentage on this page were drawn from real fertility (healthcare 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 fertility 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 40 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 fertility 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.
40 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. AI outputs vary with model version, location and time — figures describe this sample and window, and are refreshed each edition. Read the full methodology →
