ChatGPT has hidden its fan-out queries - here's how to get them back with n8n
Key findings
Dates the disappearance of the fan-out field from the UI JSON to GPT-5.3/5.4 and shows a detour via the Responses API.
Author update (25 Aug 2026)
Dan George closed the loop: after our outdated flag he checked his own GPT-5.6 browser session, found search_model_queries populated again, and added a dated note to the article ("Update, August 2026") - citing this register page as independent corroboration. His conclusion matches ours: the field's visibility fluctuates across model versions, his API route is unaffected. The outdated status stands - it refers to the claim as of its date, not to today's article.
Checked against our data
Describes a model phase before our measurement series. In our data the field is back - an example that a "vanished" field can return, and that you should check your own HAR before rebuilding an extractor.
| Claim | Status | Evidence |
|---|---|---|
| search_model_queries vanished from the UI JSON with GPT-5.3, fully with GPT-5.4; workaround via the Responses API (web_search_call -> item.action.queries) | outdated Author confirmed · 25 Aug 2026 | In our data search_model_queries is back in the messages format, both in the metadata and in the SSE stream; the fan-out is readable via the web.run call anyway. Author-confirmed: on 25 Aug 2026 Dan George reproduced our finding in his own GPT-5.6 capture and added a dated update note to the article, pointing to this register page. |
