> This also means that no companies that work with th DoD can use anthropic models for any purpose.

No, it does not mean that. I don't know why people have been making this claim. If you work for a company, let's call it X, and your work is not DOD related, let's say you work on a social media service, then X has no reason (from this designation) to prevent you from using Anthropic, it will not impact their defense contracts at all.

Dario wanted to sell a $200 million chat bot to the US military and also dictate how it could be used. The government said no. And because of that Claude also cannot be deployed to the GenAI.mil AI infrastructure. This means that any sensitive work for the DoD that uses Claude will go through Anthropic's infrastructure, not the US military-hosted backend.

So yes obviously defense contractors are forbidden to use it.
