Web Crawler
What is MistralAI-Training?
Mistral identifies this crawler as collecting web content to help build datasets for training its generative-AI models. It says the bot is not used for search indexing or live answers in Vibe; those functions have separate identities. Mistral documents the full header and says site owners can disallow MistralAI-Training in robots.txt. Treat this as a training-purpose crawler rather than a search crawler.
