Analysis

GPTBot and ClaudeBot are the two most prominent AI training data crawlers. GPTBot collects data for OpenAI's GPT models (ChatGPT, GPT-4) at moderate rates (~100 pages/hour), while ClaudeBot crawls for Anthropic's Claude models at higher rates (~500 pages/hour).

Both respect robots.txt, but their impact differs: blocking GPTBot affects GPT model training but not ChatGPT browsing or search; blocking ClaudeBot affects Claude training but not Claude-User browsing or Claude-SearchBot indexing. Both companies offer granular user-agent separation between training, browsing, and search crawlers.

When to manage GPTBot

Block GPTBot if you want to prevent OpenAI from using your content for model training while still allowing ChatGPT-User (browsing) and OAI-SearchBot (search) access.

How to block GPTBot

When to manage ClaudeBot

Block ClaudeBot if you want to prevent Anthropic from using your content for Claude model training. Note ClaudeBot crawls more aggressively (~5x GPTBot's rate).
