cohere-ai
cohere-ai is the training crawler run by Cohere: collects web pages for Cohere's language models. Its operator publishes no IP ranges or DNS names for it, so a request carrying this name cannot be verified. Treat the name in a log line as a claim.

User-agent: cohere-ai Allow: /
Add a group that names it: "User-agent: cohere-ai" followed by "Disallow: /". A crawler follows only the most specific group that names it, so once a group names cohere-ai, rules under "User-agent: *" no longer apply to it; repeat in that group any Disallow lines you still want.
What blocking it changes
No. It collects pages for training. Refusing it is a policy choice about training, separate from whether answer engines can reach, read and quote the site.
