GPTBot

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

Check if your site allows GPTBot

Operator

OpenAI

Job

Model training

Collects pages for training future models. Slower to pay off, and separate from search and citations.

robots.txt

Follows robots.txt

OpenAI says disallowing GPTBot signals that a site's content should not be used to train its foundation models.

User agent

How it identifies itself

Copied from the vendor's documentation. Version numbers inside these strings change over time, so match on the token rather than the whole string.
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko); compatible; GPTBot/1.4; +https://openai.com/gptbot

robots.txt

Allow or block GPTBot

Add one of these groups to the robots.txt at the root of your domain.

A crawler obeys only the most specific group that names it (RFC 9309), so a named group does not inherit the rules under User-agent: *. Repeat any paths you keep private, as the example does with /admin/.

Allow GPTBot
User-agent: GPTBot
Allow: /
Disallow: /admin/
Block GPTBot
User-agent: GPTBot
Disallow: /
What tryrankwise.com does

We name GPTBot and let it in

Read from the robots.txt we serve. We want AI engines to read and cite this site, so every AI crawler is allowed everywhere except the app, the API and the sign-in pages (/dashboard/, /api/, /login, /signup, /sign-in, /sign-up). The file also declares Content-Signal: ai-train=yes, search=yes, ai-input=yes.

tryrankwise.com/robots.txt
User-agent: GPTBot
Allow: /
Disallow: /dashboard/
Disallow: /api/
Disallow: /login
Disallow: /signup
Disallow: /sign-in
Disallow: /sign-up

See the whole file. The same rules repeat in every group, because a crawler that matches a named group ignores the wildcard one.

Worth knowing

More from OpenAI

  • Blocking GPTBot does not remove you from ChatGPT search. OpenAI documents OAI-SearchBot as the separate search control.
