Two model paths compared on a shared grid

How can you compare OpenAI and Gemini fanout?

Run the same topic once with each provider, keep locale fixed, save both results and compare them locally. The browser shows exact query overlaps and each run side by side without another API request.

Use this before comparing providers or the same provider on different dates.

Keep the comparison setup fixed

Use the same topic, language and country, run observations close together and record each exact model. The tool sends one provider request at a time so cost and failures remain visible.

Select at least two saved runs and choose Compare. The browser calculates exact query matches and shared source domains without a provider request. History stays on this device for up to 30 days.

Compare exposed query strings, user jobs and sources at the scope supplied. Exact overlap is objective but narrow; semantic grouping finds paraphrases but introduces judgment.

Gemini has an additional storage boundary

Google restricts reuse of Grounded Results and Search Suggestions. The site removes that data before local saving and does not publish a retained Gemini transcript.

A benchmark needs a declared sample, repetitions, missing-result rules, stable versions, cost reporting and a method chosen before results. This view compares selected observations only.

Zero queries can be an honest result

The provider may decide the topic needs no web search, or may search without exposing a reusable query string. The native result should remain zero; filling it with likely searches would turn observation into guesswork.

A completed zero-query run may still include provider status or usage. Timeout, CAPTCHA failure, quota stop, invalid response and provider errors should appear explicitly, not as empty success.

Use one topic up to 60 characters. Avoid URLs, multiple questions or instructions about how many searches to perform. A narrow fact may legitimately require only one search or none.

Search Ideas is a separate fallback

For brainstorming, switch to Search Ideas. It generates research directions without web search. Keep that label: modelled ideas do not reveal what the native provider searched.

Record provider, model, time, locale, visible status and public error code. Never send an API key or private raw response. Those details help distinguish normal zero behavior from a parser regression.

Common questions

These short answers cover recurring questions from tool use and source review. They are not claimed search-volume data.

Is an OpenAI-versus-Gemini result a benchmark?
No. Two saved runs show what those API calls exposed under one setup. They do not establish general model quality, consumer-product behavior or a statistically reliable winner.
When is it a provider comparison and when a date comparison?
The tool labels equal topics across different providers as a provider comparison. Equal topics from the same provider on different dates form a date comparison; mixed selections are labelled accordingly.
Why is Gemini evidence not part of the public corpus?
The current rights boundary permits browser-local use but does not establish publication rights for retained Gemini Grounded Results or Search Suggestions. Public examples therefore remain limited to reviewed OpenAI owner-run observations.
