2% of 30,223 measured domains disallow cohere-training-data-crawler in robots.txt at the site root. Separately, and independently of robots.txt, 17.4% of 30,223 reachable domains refuse an AI crawler user agent at the network edge on two consecutive probes from different locations - a refusal the site's own robots.txt does not declare and its owner often has not chosen.

What it is definition
Downloads training data for the large language models behind Cohere's enterprise AI products.
cohere-training-data-crawler is operated by Cohere and classified here as model training. These agents collect text and images that may end up in a training corpus. Disallowing one withholds new content from the next model. It does not withdraw anything collected before the disallow, and it does not remove the site from any answer engine.
Disallowing cohere-training-data-crawler withholds content crawled from that point on from Cohere's training data. It does not withdraw pages collected in earlier crawls, it does not reach copies already sitting in third-party datasets, and it does not remove the site from any answer surface.

How to allow it, how to block it robots.txt
User-agent: cohere-training-data-crawler
Allow: /Absent any rule, the agent is already allowed, so this group only matters when your * group disallows something. Naming the agent replaces the * group for it entirely, so repeat here every disallow you still want to apply to it.
User-agent: cohere-training-data-crawler

It does not withdraw pages collected in earlier crawls, it does not reach copies already sitting in third-party datasets, and it does not remove the site from any answer surface.

Common questions answered
Does blocking cohere-training-data-crawler remove me from Cohere's models?
No, not by itself. cohere-training-data-crawler collects content for training, not for the index that answers questions. Cohere's answer surfaces are governed separately by cohere-ai, which stays allowed unless you disallow it too. Content collected before the disallow is not withdrawn.
How do I verify cohere-training-data-crawler requests are genuine?
Cohere publishes neither reverse DNS names nor address ranges for cohere-training-data-crawler, so a request carrying this user agent cannot be authenticated. The string is trivially spoofed and is routinely reused by unrelated scrapers. Treat it as a hint, rate-limit by source address, and do not grant it access you would not grant an anonymous client.
