OAI-SearchBot: what it is, its IP ranges, and how to block it

OAI-SearchBot is OpenAI's crawler for AI search and answers.

Vendor	OpenAI
What it is for	AI search and answers
In its User-Agent	`OAI-SearchBot`
Its vendor's address list	`https://openai.com/searchbot.json`
IP ranges	39

It reads a page for an AI's search or for a person who asked an assistant, and can bring visitors. Bot Protection lets it through by default; you can block it.

How to verify it

Any bot can write OAI-SearchBot in its User-Agent. A request is OAI-SearchBot only when its address is in OpenAI's published list below: check the address, not the name.

How to block it

With robots.txt, you ask it to stay out:

User-agent: OAI-SearchBot
Disallow: /

robots.txt is a request, not a block, and it cannot tell the real crawler from a bot wearing its name. Bot Protection verifies OAI-SearchBot by its address on every request and answers it as you choose on the Set-up page, per kind or for OAI-SearchBot alone; a bot that only wears the name is judged like any other bot.
