cohere-training-data-crawler is Cohere's dedicated web crawler for collecting training data for their enterprise large language models. This is distinct from the Cohere-Ai user agent, which is used for real-time content retrieval. The training data crawler performs broader web crawling to gather diverse text content that improves Cohere's models. It respects robots.txt directives, allowing website owners to opt out of having their content used for Cohere's model training.
