What Is GPTBot?
GPTBot is the web crawler operated by OpenAI to collect publicly accessible web content for training its GPT language models (GPT-4, ChatGPT, etc.). It identifies itself with the user-agent string GPTBot/1.0 and respects robots.txt directives. OpenAI publishes the IP ranges used by GPTBot for verification.
Why GPTBot Matters
GPTBot is one of the most active AI crawlers on the web. If you do not explicitly block it in robots.txt, it will crawl your site and potentially use your content for AI training. Many publishers have chosen to block GPTBot to protect their content, while others allow it in exchange for potential visibility in ChatGPT responses.
How to Block or Allow GPTBot
To block: add User-agent: GPTBot and Disallow: / to your robots.txt. To verify GPTBot requests in your logs, check the user-agent string and cross-reference the IP with OpenAI's published ranges. Monitor GPTBot activity with LogBeast.
