GPTBot
OpenAI's training crawler; blocking it in robots.txt opts a site's content out of training OpenAI's foundation models without affecting ChatGPT search visibility.

Short answer
GPTBot is OpenAI's web crawler used to collect content for training its foundation models. Blocking GPTBot in a site's robots.txt opts that site's content out of future model training. It does not affect visibility in ChatGPT search, which relies on a separate crawler, OAI-SearchBot, so publishers can manage the two independently.
