MistralAI-Training
Mistral AI · Training · robots.txt: Yes
Crawls web content to help build datasets for training Mistral’s generative AI models.
Block MistralAI-Training
User-agent: MistralAI-Training
Disallow: /Blocking MistralAI-Training opts your content out of Mistral’s training datasets. Mistral says this crawler is not used for search indexing or to answer live questions in Vibe, so blocking it does not affect those.
Allow MistralAI-Training
User-agent: MistralAI-Training
Allow: /An allow group only changes anything if a broader rule would block MistralAI-Training. Under the robots.txt standard (RFC 9309, section 2.2.1) a crawler follows the group that names it and uses the User-agent: * group only when no group does — so this group lets it in even if your * group says Disallow: /. Token matching is case-insensitive.
Put these lines in /robots.txt at the root of each host (each subdomain has its own file). robots.txt is a request to well-behaved crawlers, not access control.
