The most comprehensive public teardown of ChatGPT search: classifier, fan-out engine, provider ecosystem, entity linking, fusion, shopping, maps and news modules, feature gates, citation types.
The citation types and the fan-out modes match our reference and mode fields. Much else is derived from the frontend bundle and not verifiable from the client. The teardown is the map, the tracker measures individual streets on it.
| Claim | Status | Evidence |
|---|---|---|
| Sonic classifier, fan-out engine (Search/Shopping/Images), providers SerpAPI/SearchAPI.io/Getty/Google Places | unverifiable | Providers server-side. Fan-out types visible for us as modes fast/slow/product/image/business. |
| Statsig feature gates: 424 gates, 99 dynamic configs, 237 layer configs | unverifiable | We capture settings_keys (44) and feature_flags from /settings/user, not the Statsig bundle. |
| Three citation types: Citations, More sources, Hidden links | confirmed | url (in the text), sources_footnote (list), grouped_webpages/search_result_groups (object only). |
