What it is definition

Crawls content that may be used to train OpenAI's generative AI foundation models.

GPTBot is operated by OpenAI and classified here as model training. These agents collect text and images that may end up in a training corpus. Disallowing one withholds new content from the next model. It does not withdraw anything collected before the disallow, and it does not remove the site from any answer engine.

Disallowing gptbot withholds content crawled from that point on from OpenAI's training data. It does not withdraw pages collected in earlier crawls, it does not reach copies already sitting in third-party datasets, and it does not remove the site from any answer surface.

How to allow it, how to block it robots.txt

Allow it
User-agent: gptbot
Allow: /

Absent any rule, the agent is already allowed, so this group only matters when your * group disallows something. Naming the agent replaces the * group for it entirely, so repeat here every disallow you still want to apply to it.

Block it
User-agent: gptbot
Disallow: /

Disallowing gptbot withholds content crawled from that point on from OpenAI's training data. It does not withdraw pages collected in earlier crawls, it does not reach copies already sitting in third-party datasets, and it does not remove the site from any answer surface.

Common questions answered

Does blocking GPTBot remove me from ChatGPT?

No, not by itself. GPTBot collects content for training, not for the index that answers questions. OpenAI's answer surfaces are governed separately by oai-searchbot, chatgpt-user and oai-adsbot, which stay allowed unless you disallow them too. Content collected before the disallow is not withdrawn.

How do I verify GPTBot requests are genuine?

OpenAI publishes the address ranges its crawlers fetch from as JSON files linked from its bot documentation, one file per agent. Compare the source address of the request against the file for that agent. There is no reverse DNS name to check, so the address list is the only signal.
