What is cohere-training-data-crawler?

The cohere-training-data-crawler is a specialized web crawler from Cohere, an AI company that develops large language models (LLMs) for enterprise use. As an AI data scraper, its function is to systematically collect public text data from websites to be used in training Cohere's language models. The crawler identifies itself in server logs with the user-agent string cohere-training-data-crawler. It is optimized for high-quality data extraction and is designed to adhere to the robots.txt protocol, respecting any specified crawling directives.

Why is cohere-training-data-crawler crawling my site?

The cohere-training-data-crawler is visiting your site to gather public text content for training its language models. It prioritizes websites with high information density, regularly updated content, and domain-specific expertise. The quality and usefulness of the content for AI training are more important than a site's general popularity. Its crawl frequency depends on your site's content update patterns and its perceived value for training data, but it follows standard crawling practices to avoid overloading servers.

What is the purpose of cohere-training-data-crawler?

The main purpose of this crawler is to collect diverse, high-quality text data to train and improve Cohere's large language models. These models are the foundation for a wide range of enterprise AI applications, including text generation, sentiment analysis, and semantic understanding. Unlike search engine crawlers that index content to provide search results and drive traffic, this crawler repurposes data for machine learning. This raises different considerations around data usage and intellectual property for website owners.

How do I block cohere-training-data-crawler?

If you do not want your website's content to be used for training Cohere's AI models, you can block their crawler by adding a disallow rule to your robots.txt file.

To block this bot, add the following lines to your robots.txt file:

User-agent: cohere-training-data-crawler
Disallow: /

How to verify the authenticity of the user-agent operated by Cohere?

Reverse IP lookup technique

To verify user-agent authenticity, you can use host linux command two times with the IP address of the requester.
  1. > host IPAddressOfRequest
    This command returns the reverse lookup hostname (e.g., 4.4.8.8.in-addr.arpa.).
  2. > host ReverseDNSFromTheOutputOfFirstRequest
If the output matches the original IP address and the domain is associated with a trusted operator (e.g., Cohere), the user-agent can be considered legitimate.

IP list lookup technique

Some operators provide a public list of IP addresses used by their crawlers. This list can be cross-referenced to verify a user-agent's authenticity. However, both operators and website owners may find it challenging to maintain an up-to-date list, so use this method with caution and in conjunction with other verification techniques.
