GPTBot vs OAI-SearchBot: What's the Difference?

GPTBot is OpenAI's training crawler (turns your content into model weights, no traffic back). OAI-SearchBot is its search crawler (cites you in ChatGPT answers with a link). Block one, allow the other.

GPTBot vs OAI-SearchBot: What’s the Difference?

By Andrej Ruckij · June 16, 2026

TL;DR: GPTBot is OpenAI’s training crawler — it collects content to train models and gives nothing back. OAI-SearchBot is OpenAI’s search crawler — it indexes your content to cite you in ChatGPT answers, with a link. The standard move is to block GPTBot and allow OAI-SearchBot.

The direct answer

Both are OpenAI crawlers, but they do opposite-value jobs for a site owner:

GPTBotOAI-SearchBot
PurposeTrain OpenAI’s modelsIndex content for ChatGPT search
What you get backNothing (no link, no traffic)Citations + referral clicks
CategoryTrainingRetrieval / search
Typical decisionBlockAllow

Blocking GPTBot opts you out of training; allowing OAI-SearchBot keeps you visible and citable in ChatGPT. They’re independent, so you can do both at once.

Why the distinction matters

This single distinction is the whole strategic framework for OpenAI access. People who block “OpenAI” wholesale often mean “don’t train on me” but accidentally also cut themselves out of ChatGPT search — because they didn’t realize the two bots are separate. Keeping them straight lets you protect your content from free training without sacrificing AI-search visibility. (A third bot, ChatGPT-User, fires when a real person opens your page via ChatGPT — that’s a visitor, always allow it.)

How to apply it

User-agent: GPTBot
Disallow: /

User-agent: OAI-SearchBot
Allow: /
User-agent: ChatGPT-User
Allow: /

Both bots respect robots.txt and OpenAI publishes IP ranges for each, so you can verify them. Just confirm no CDN-level “block all AI” rule is overriding the Allow for OAI-SearchBot (robots-txt-vs-waf-ai-bots).

Key takeaways

  • GPTBot = training (block to opt out, no traffic cost).
  • OAI-SearchBot = search (allow to stay citable in ChatGPT).
  • They’re independent; the clean split is “block training, allow search.”
