Cloudflare says OpenAI pilot indexed hundreds of millions of new pages from 1% of its network for ChatGPT Search

Cloudflare says a research pilot launched with OpenAI in July 2026 used a participating cohort of about 1% of Cloudflare’s network to help OpenAI discover and index hundreds of millions of previously unknown pages for ChatGPT Search. The companies are testing signals for filtering nonexistent, duplicated, redirected, changed, and potentially harmful pages, while Cloudflare says the work uses web metadata for search discovery rather than sharing page content for model training.

For site owners that want AI discovery, Cloudflare’s reported change and filtering signals could reduce wasted crawler load while making more pages eligible for ChatGPT Search. The trade-off is that newly discovered pages may initially increase crawling while they are evaluated, and the article does not yet show whether indexing leads to measurable referrals, citations, or business outcomes.
