## What is ChatGPT-User?

Fetches pages for user actions in ChatGPT and custom GPTs.

## How to identify it

Look for the ChatGPT-User identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.

## How to check identity

Compare the request IP with the current operator-published ranges linked in the source. A matching name alone does not verify identity.

## Access and robots.txt

User-initiated requests may not follow robots.txt.

## What it means in your analytics

A verified fetch can reflect a user asking ChatGPT to retrieve a page. Nearby requests alone do not identify one person or one task.

## Useful measures

Requested public pages; Public-page 403 and 404 responses; Subsequent page requests.

## What to check next

Inspect the requested public page and next requests. A 403 can interrupt research; a 404 can indicate an outdated or guessed URL.
