In the Sep run, ChatGPT repeated a documented false claim in 12.6% of its substantive answers to P2 news-style questions in Germany — its worst market — and cited a watchlisted domain in 6.6% of its answers there. Markets are shown side by side below and never merged. OpenAI has been notified of every finding on this page that carries a date.

Change between runs

Repeat rate for this assistant across comparable runs in one market
Run	Repeat-rate	Change
20 Jul 2026 · United States	17.3%11–26 · n=104
3 Sep 2026 · United States	8.4%4–15 · n=107	−8.9pp not significant

There is no control group. A change here cannot be separated from a model update in the same window, so this is the change observed after the disclosure, not the effect of it. Model versions are recorded on both sides, and the figures are persona P2 only in US-EN only.

Between two runs a month apart, much of the source set would have changed on its own: Cross-industry GEO tooling (Peec.ai, Profound, Otterly) puts month-to-month citation drift at 54.1% for ChatGPT — an external figure, not one of ours. Roughly half the domains cited in July would be gone by September without anyone touching anything, so a change that clears significance is still not, on its own, evidence that the fault was fixed.

What it did with the claims

The four outcomes as shares of every valid answer, one row per question type per market. Never collapsed into one number: the question types trigger different failure modes, and averaging them describes nobody.

Searching, and what it found

How often this assistant cited anything at all, and how often what it cited included a listed source. Contamination concentrates on news-style questions rather than hostile ones: an ordinary question sends the assistant to search, and search is where listed sources sit beside legitimate coverage.

Citation drift

The share of the domains an assistant cites that changes from one month to the next, for reasons unrelated to anything we or the platform do. This is an external figure, not one of ours — it is here because a change between our runs has to be read against it.

Published month-to-month citation drift by product
Product	Cited domains that change month to month
Perplexity	40.5%
ChatGPT — this assistant	54.1%
Copilot	53.4%
Google AI Overviews	59.3%

Source: Cross-industry GEO tooling (Peec.ai, Profound, Otterly). External figure, not a Citere measurement. The share of domains an assistant cites that changes from one month to the next, independent of anything Citere or the platform does.

Where it does worst

No two markets differ significantly for this assistant: every pair of intervals overlaps, so any difference between them is directional and this page does not claim it.
