OAI-SearchBot is OpenAI's dedicated web crawler user-agent token used exclusively for fetching live web content to answer user queries in ChatGPT's search functionality. Unlike GPTBot, which collects data for foundation model training, OAI-SearchBot's sole purpose is real-time retrieval and citation, making it functionally analogous to a search engine indexer rather than a data harvesting bot.
Glossary
OAI-SearchBot
A distinct OpenAI user-agent token used to identify its crawler when it accesses websites specifically for providing real-time search results in ChatGPT, separate from its training crawler.
AI CRAWLER DIRECTIVES
What is OAI-SearchBot?
OAI-SearchBot is a distinct user-agent token deployed by OpenAI to identify its crawler when accessing websites for the specific purpose of providing real-time search results and grounding responses in ChatGPT, separate from its training crawler GPTBot.
Publishers can manage OAI-SearchBot independently in robots.txt using its full user-agent token string. Disallowing OAI-SearchBot prevents a site's content from appearing as a cited source in ChatGPT's search results while still permitting access to GPTBot for training purposes, enabling granular control over how OpenAI's distinct crawler types interact with proprietary web assets.
CRAWLER IDENTITY
Key Characteristics of OAI-SearchBot
OAI-SearchBot is a distinct user-agent token deployed by OpenAI to power real-time search capabilities in ChatGPT. It is architecturally and functionally separate from the training crawler (GPTBot), allowing webmasters granular control over how their content is accessed.
01
Purpose-Built for Real-Time Grounding
Unlike GPTBot, which collects data for foundation model training, OAI-SearchBot is exclusively used to fetch live web content to answer user queries in ChatGPT. It acts as a retrieval agent, not a training data collector. This separation allows publishers to permit their content to appear in AI-generated search results while explicitly blocking its use for model training.

03
Respects Standard Exclusion Protocols
OAI-SearchBot adheres to the Robots Exclusion Protocol (robots.txt) and standard HTML meta tags. If a page is disallowed via robots.txt or contains a noindex meta tag, the bot will not access or display that content in ChatGPT's search results. It also respects the Crawl-Delay directive to manage server load.
04
Citation and Attribution Model
When OAI-SearchBot retrieves content for a response, ChatGPT provides inline citations and source links to the original web pages. This attribution mechanism drives referral traffic to publishers who allow crawling. The bot fetches the full page content to ensure accurate summarization and factual grounding, but only displays snippets with clear provenance.
05
Separate from Training Data Pipelines
Content accessed by OAI-SearchBot is not used for model training. OpenAI maintains a strict data firewall between its search crawler and its training infrastructure. This architectural separation is a critical trust signal for publishers who want to participate in the generative search ecosystem without contributing their proprietary data to foundation model weights.

Frequently Asked Questions
Quick, precise answers to the most common questions about OpenAI's dedicated search indexing bot and how it differs from its training crawlers.
OAI-SearchBot is a distinct user-agent token used by OpenAI to identify its crawler when it accesses websites specifically for providing real-time search results in ChatGPT, separate from its training crawler. When a user asks ChatGPT a question requiring current information, OAI-SearchBot fetches and indexes web pages to ground the response with live data. It respects robots.txt directives and operates independently from GPTBot, ensuring that content accessed for search grounding is not automatically used for foundation model training. This separation gives publishers granular control over how their content is consumed by OpenAI's ecosystem.
