OAI-SearchBot identifies itself with the token OAI-SearchBot. That is the case-insensitive substring to grep for in access logs, and the exact name to put after User-agent: in robots.txt. It builds the index an AI search product answers from.

Allow or block OAI-SearchBot in robots.txt

Robots.txt applies the most specific matching group, so a group naming OAI-SearchBot overrides your User-agent: * rules for this bot alone.

Allow
User-agent: OAI-SearchBot
Allow: /
Block
User-agent: OAI-SearchBot
Disallow: /

What blocking costs you: You won't be cited in ChatGPT Search results.

Blocking one OpenAI bot does not block the others — each token is a separate group.

Can OAI-SearchBot be spoofed?
Yes. A User-Agent header is self-reported, so any scraper can claim to be OAI-SearchBot. The token is fine for reporting and for robots.txt, but if you are rate-limiting or firewalling on it, verify the request IP against OpenAI's published ranges before you trust the name.
