How to block MistralAI-Training
Collects text that may be used to train AI models. Blocking it keeps your pages out of future training data. AI answers can still cite you through the search crawlers.
Block the whole site
Add this group to robots.txt at the root of your site.
User-agent: MistralAI-Training Disallow: /
Block only some paths
List the paths; everything else stays open to MistralAI-Training.
User-agent: MistralAI-Training Disallow: /private/ Disallow: /drafts/
How to verify MistralAI-Training
Anyone can send a crawler's user-agent string. Where the request comes from is what proves it.
- 1
Find requests whose user agent contains "MistralAI-Training" in your server or CDN logs.
- 2
Mistral publishes no IP list for MistralAI-Training, so it cannot be verified from the request alone. Treat unusual volume as a scraper using its name, and rate-limit or block it at the firewall.
- 3
Block what fails the check at the firewall. A robots.txt rule only reaches crawlers that choose to read it.
Other crawlers from Mistral
Each has its own token, and blocking one leaves the others untouched.
