Where they disagree

The behaviors where the choice of model changes the answer.

The divergence index for this study is 25.2 points — the average distance between the most and least likely model across the coded behaviors. The gaps below are where which assistant a german auto repair buyer happens to ask matters most:

  • Asks a clarifying question: from 6.7% (Gemini) to 80% (ChatGPT) — a 73-point spread.
  • Recommends hiring a professional: from 46.7% (Gemini) to 86.7% (ChatGPT) — a 40-point spread.
  • Tells the buyer to check reviews: from 0% (Gemini) to 26.7% (Claude) — a 27-point spread.
  • Mentions local proximity: from 13.3% (Claude) to 40% (ChatGPT) — a 27-point spread.
  • Gives selection criteria: from 33.3% (Gemini) to 53.3% (Claude) — a 20-point spread.

The widest single gap — asks a clarifying question, 73 points — means a german auto repair 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 german auto repair market.

Where they agree

Trust signals

How well the models protect the german auto repair buyer.

Beyond whether to hire, the rubric codes how carefully each assistant protects the german auto repair 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 20%. Warning about red flags or scams appeared in 13.3%.

On structuring the decision, a selection-criteria checklist showed up in 42.2% of answers on average and a recommendation to gather multiple quotes in 4.4%. The single least-reproduced protective signal for german auto repair is "recommends multiple quotes" at 4.4% 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 German Auto Repair providers?

For service providers the decisive question is whether these systems name anyone at all. Across 45 german auto repair answers, a specific provider was named in 11.1% of responses on average — roughly 0.6 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for german auto repair: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.

Each was put to all 3 models once, with identical wording, so the rates above describe how the assistants handled this exact german auto repair question set — not a general prior or a hand-picked subset.

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 german auto repair question set and snapshot rather than a general prior. The full protocol and coding rubric are documented in the study methodology.
