By model
How each assistant handled Dumpster questions.
Reading the 120 answers model by model shows how differently the three assistants treat the same dumpster questions. On the most consequential behavior, whether to send the buyer to a professional at all, the rate ranged from 52.5% (ChatGPT) down to 30% (Gemini), a 23-point gap on an identical question set.
Across the 40 dumpster answers it produced, ChatGPT recommended hiring a professional in 52.5% of them and suggested a DIY approach first 27.5% 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 22.5% of the time. ChatGPT asked a clarifying question before answering in 70% of cases, warned about red flags or scams in 7.5%, and told the buyer to verify credentials in 17.5%, averaging 405 words per answer. On the remaining cues it told the buyer to check reviews in 7.5%, pointed to case studies or a portfolio in 0%, and framed the choice around local proximity in 45%; a selection-criteria checklist appeared in 37.5% of its answers and a recommendation to gather multiple quotes in 17.5%.
Across the 40 dumpster answers it produced, Claude recommended hiring a professional in 45% of them and suggested a DIY approach first 12.5% of the time. It named a specific provider in 10% of answers (about 0.2 distinct providers per answer) and included price or cost information 17.5% of the time. Claude asked a clarifying question before answering in 67.5% of cases, warned about red flags or scams in 5%, and told the buyer to verify credentials in 5%, averaging 257 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 35%; a selection-criteria checklist appeared in 32.5% of its answers and a recommendation to gather multiple quotes in 15%.
Across the 40 dumpster answers it produced, Gemini recommended hiring a professional in 30% of them and suggested a DIY approach first 15% of the time. It named a specific provider in 7.5% of answers (about 0.4 distinct providers per answer) and included price or cost information 37.5% 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 0%, averaging 294 words per answer. On the remaining cues it told the buyer to check reviews in 0%, pointed to case studies or a portfolio in 0%, and framed the choice around local proximity in 22.5%; a selection-criteria checklist appeared in 17.5% of its answers and a recommendation to gather multiple quotes in 2.5%.
Taken together, ChatGPT is the assistant most likely to route a dumpster buyer to a professional (52.5%) and Gemini the least (30%). ChatGPT produced the longest answers, at 405 words on average. Specific providers were named most often by Claude (10%). Even there, roughly one answer in 10 carried a name.
Where they disagree
The behaviors where the choice of model changes the answer.
Question-level model disagreement is 18.3%. This is 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 dumpster buyer happens to ask matters most:
- Asks a clarifying question: from 2.5% (Gemini) to 70% (ChatGPT). The spread is 68 points.
- Recommends hiring a professional: from 30% (Gemini) to 52.5% (ChatGPT). The spread is 23 points.
- Mentions local proximity: from 22.5% (Gemini) to 45% (ChatGPT). The spread is 23 points.
- Gives price or cost information: from 17.5% (Claude) to 37.5% (Gemini). The spread is 20 points.
- Gives selection criteria: from 17.5% (Gemini) to 37.5% (ChatGPT). The spread is 20 points.
The widest single gap concerns asks a clarifying question at 68 points. This means a dumpster 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 dumpster market.
Where they agree
The points of near-consensus in Dumpster.
On other behaviors the three models move almost in lockstep. The points of near-consensus for dumpster, where all three landed within a few points of each other:
- Mentions case studies or portfolio: 0% across all three models.
- Names a specific provider: 7.5%–10% across all three (a 3-point spread).
- Warns about red flags or scams: 5%–7.5% across all three (a 3-point spread).
- Tells the buyer to check reviews: 0%–7.5% 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" (17.5%).

Trust signals
How well the models protect the dumpster buyer.
Beyond whether to hire, the rubric codes how carefully each assistant protects the dumpster buyer once a decision is made. Telling the buyer to check reviews or ratings appeared in 4.2% of answers on average. Verifying credentials or certifications appeared in 7.5%. Warning about red flags or scams appeared in 6.7%.
On structuring the decision, a selection-criteria checklist showed up in 29.2% of answers on average and a recommendation to gather multiple quotes in 11.7%. The single least-reproduced protective signal for dumpster is "tells the buyer to check reviews" at 4.2% on average. This is 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 Dumpster providers?
For service providers the decisive question is whether these systems name anyone at all. Across 120 dumpster answers, a specific provider was named in 8.3% of responses on average, or roughly 0.3 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for dumpster: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.
The question set
What these 40 Dumpster questions cover.
The 40 questions behind every percentage on this page form a frozen dumpster (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 dumpster question set rather than 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. It is not a confidence score. Because each model answered every question exactly once on 2026-07-06, the figures describe this specific dumpster 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 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 2026-07-06 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 →
