OAI-SearchBot vs GPTBot: which should you allow?

OpenAI runs two different crawlers, and they do different jobs — so “should I allow GPTBot?” has a more useful answer than yes or no. Here’s what OAI-SearchBot and GPTBot each do, how to decide, and the exact robots.txt for every choice — including the popular middle ground: appear in ChatGPT’s answers without feeding model training.

GPTBot = trainingGathers web data used to train and improve OpenAI’s models. Allowing it makes your content eligible to shape what ChatGPT “knows”.
OAI-SearchBot = live answersFetches pages for ChatGPT’s live search and browsing, and for citations in real-time answers. This is the one that gets you cited today.
Most sites: allow bothIf you want maximum AI visibility, allow both — training familiarity plus live-answer citations.
Publishers: the middle groundAllow OAI-SearchBot (be cited in answers) but block GPTBot (don’t feed training) — common for news and premium content.

The short answer

GPTBot is OpenAI’s training crawler; OAI-SearchBot is its live-search/browsing crawler. For most brands that want to be recommended, allow BOTH. If you’re a publisher who wants to appear in ChatGPT’s answers but not contribute to model training, allow OAI-SearchBot and block GPTBot. The one choice to avoid (if visibility matters) is blocking OAI-SearchBot, because that’s what removes you from live ChatGPT answers and citations.

What GPTBot does

GPTBot is the crawler OpenAI uses to collect publicly available web data for training and improving its models. Allowing it means your content can inform the model’s general knowledge over time. It does not directly place you in a specific live answer — that’s OAI-SearchBot’s job — but broad training familiarity can still help a model recognise your brand.

What OAI-SearchBot does

OAI-SearchBot fetches pages for ChatGPT’s live search and browsing features, and it’s the crawler behind the sources ChatGPT cites in real time. If you care about showing up when a user asks ChatGPT a question today, this is the crawler that must be able to read you.

How to decide

Match the choice to your goal:

  • Want maximum AI visibility (most businesses): allow BOTH GPTBot and OAI-SearchBot.
  • Want live-answer citations but not to feed training (many publishers): allow OAI-SearchBot, block GPTBot.
  • Highly sensitive/paywalled content: block both, and accept you won’t appear in ChatGPT.
  • Never block ONLY OAI-SearchBot while allowing GPTBot — that feeds training but removes you from the live answers where buyers actually see you.

The exact robots.txt for each choice

Allow both (recommended for visibility), or the publisher middle ground:

# Option A — allow BOTH (maximum AI visibility)
User-agent: GPTBot
Allow: /

User-agent: OAI-SearchBot
Allow: /

# Option B — appear in ChatGPT answers, but NOT in training
User-agent: GPTBot
Disallow: /

User-agent: OAI-SearchBot
Allow: /

After you change it

robots.txt changes are picked up when OpenAI’s crawlers next re-read your site — usually days to a couple of weeks. Confirm your live robots.txt reflects the choice you intended, and remember that allowing a crawler only helps if your content is in the static HTML it can actually read.

FAQ

What is the difference between OAI-SearchBot and GPTBot?

GPTBot is OpenAI’s training crawler (collects data to improve its models); OAI-SearchBot is its live-search crawler (fetches pages for ChatGPT’s real-time answers and citations). OAI-SearchBot is the one that gets you cited in answers today.

Should I allow GPTBot?

If you want maximum AI visibility, yes — allow it alongside OAI-SearchBot. If you want to appear in ChatGPT’s answers but not feed model training, block GPTBot and allow OAI-SearchBot instead.

Can I appear in ChatGPT without letting OpenAI train on my content?

Yes — allow OAI-SearchBot (so you’re eligible for live answers and citations) and disallow GPTBot (so your content isn’t collected for training). See Option B above.

Which is worse to block — GPTBot or OAI-SearchBot?

Blocking OAI-SearchBot is worse for visibility: it removes you from ChatGPT’s live answers and citations. Blocking GPTBot only opts you out of training.
