Anthropic Clarifies Stance: We Do Not Support Banning Open-Weights Models

Our position on open-weights models

I want to clarify that Anthropic has never advocated for banning open-weights models, as they are a public good when safe. My primary concerns are authoritarian regimes using AI for military superiority and the misuse of powerful models for cyber or biological attacks. Instead of blanket bans, I support restricting chip sales to China, cracking down on industrial distillation, and mandating safety testing for all capable models, regardless of whether they are open or closed.
