Anthropic refused to sign an industry letter opposing US restrictions on Chinese open-weights models, instead publishing its own position arguing that chip export controls and mandatory safety testing are better tools than model bans. CEO Dario Amodei stated that open models without dangerous capabilities are a public good, but acknowledged elevated risks from powerful open models for cyber and biological attacks. Anthropic's stance differs from 50+ other tech companies and puts it in a smaller group advocating for export controls and pre-release safety testing rather than open-model restrictions.
