A dated time series: on 8 August 2026 ChatGPT starts, at scale, to restrict fan-outs to domains. The basis for the coverage of the Reddit drop (Forbes, 20 Aug).
Twelve days later the restriction is routine for us, mostly as a fourth pipe parameter; site: in the query text we see only at K8-01, K6-02 and K5-01 thinking. Whether Promptwatch counts both together is not clear from the page. The event itself we missed; exactly such days the tracker is meant to record on the same day in future.
| Claim | Status | Evidence |
|---|---|---|
| Share of fan-outs with site: jumped from 0.37% to 16.8% on 2026-08-08 | unverifiable | Before our measurement start. Since 20 Aug, domain restriction is the norm for us in 8 of 18 searching standard questions (instant) - as a pipe parameter, not as site:. |
| Queries per answer rose from 1.08 to 1.83 | outdated | Median 3 for us; a different counting method likely. |
