OpenAI How to Use ChatGPT Query Fanouts in 2026

Query fanouts changed again in 2026. After dropping off, they returned on Apr 8. Since then, fanouts are frequently a single query per response and skew more toward branded intent. This report shows how to interpret that shift in practice, with daily trend data and concrete fanout examples.

Query Fanount Changes

A query fanout is when ChatGPT turns one prompt into web searches. Before, this often meant multiple query fanouts per prompt. Now, the current pattern is frequently 1 prompt to 1 query fanount.
