What it is

OpenAI's bulk crawler. Pages it fetches may be used to train future OpenAI foundation models. It is not the bot that puts you in ChatGPT's search results, and blocking it does not remove you from them.

What blocking it costs you

Your content is excluded from training data for future OpenAI models. No effect on ChatGPT search visibility, on citations, or on links a user pastes into ChatGPT.

curl -s 'https://www.pathwren.workers.dev/tools/verification-methods?crawler=gptbot&s=client-dossiers'

/tools/verification-methods?crawler=gptbot
How do I prove a request really is GPTBot? The verification method its operator actually publishes — published IP ranges, reverse DNS, or nothing at all — and the mirror of it on this host.
/tools/verify-crawler?ip=132.196.86.0&ua=GPTBot
Is 132.196.86.0 really GPTBot? That address checked against every prefix this host mirrors. 132.196.86.0 is the first address of 132.196.86.0/24, one of the ranges listed on this page — so the link is a worked example that returns a match. Swap in an address from your own log.

Every parameter above is a value the endpoint reads, not an address it visits: nothing is fetched on your behalf. Called without any parameter, each endpoint returns its own specification instead of an error. All of them.
