GPTBot
OpenAI's training crawler. It collects public pages that may be used to train OpenAI's generative foundation models.
What happens if you block it
Your content is excluded from training OpenAI's foundation models. It does not affect whether you appear in ChatGPT search; that is OAI-SearchBot.
Our take
Block it if you don't want your content used for training. Blocking it alone won't remove you from ChatGPT answers.
robots.txt
To block it:
User-agent: GPTBot Disallow: /
To allow it explicitly (useful when a wider rule blocks other bots):
User-agent: GPTBot Allow: /
