What blocking GPTBot costs
Your pages stop being added to OpenAI’s training data from the moment you block it. Content already collected is not withdrawn, so this is a decision about the future and not about the past.
What it does not cost
It does not remove you from ChatGPT’s live browsing. That is OAI-SearchBot, a separate agent with a separate name, and blocking one does nothing to the other. Sites that block GPTBot expecting to disappear from ChatGPT answers are usually surprised.
OpenAI publishes its crawler IP ranges, so a request claiming to be GPTBot can be verified rather than trusted.

The other seven
The crawler behind ChatGPT’s search surface: it fetches pages so they can be cited in answers.
Anthropic’s crawler, used to gather web content for Claude.
Perplexity’s crawler, which indexes pages so they can be cited in its answers.
Not a crawler at all. It is a control token: Googlebot still fetches the page, and this decides whether the content may be used for Gemini and for grounding AI Overviews.
The same shape as Google-Extended: a control token, not a crawler. Applebot fetches the page either way; this decides whether the content may train Apple Intelligence.
The crawler behind Common Crawl, a free public archive of the web that most open training corpora are built from.
ByteDance’s crawler, gathering content used for TikTok’s search and for Doubao.
How this page is made
The explanation above is written by a person. The numbers are computed from Domduck’s own daily reads of each domain’s robots.txt, parsed to RFC 9309 rather than searched for a string: a rule binds to the nearest preceding group of user-agent lines, the longest matching pattern wins, and Allow breaks a tie. No prefix matching is done, so a group naming Google is not treated as a policy about Google-Extended. What the collectors have read.
