Anthropic CEO Dario Amodei clarified the company's stance on open-weights AI models, stating that Anthropic has never advocated for a ban. He views open-weights models without dangerous capabilities as a public good, benefiting businesses and researchers.

Amodei's primary national security concern is authoritarian governments developing AI models superior to those from the US, potentially for military dominance or repression. He argues this threat is independent of whether models are open-weights or used by US companies. A secondary concern involves the misuse of powerful AI for cyber or biological attacks, noting open-weights models can present higher risks due to difficulties in monitoring and control.

Instead of a ban, Amodei supports restricting powerful chip sales to China, cracking down on industrial-scale AI model distillation, and implementing mandatory safety testing for all sufficiently capable AI models, regardless of their origin or openness. He believes these targeted measures are more effective in addressing national security and misuse risks.
