TL; DR
Amodei says Anthropic has never called for a ban on overweight models. It supports chip export control, anti-distillation and mandatory security testing for all capable models, both open and closed.
Dario Amodei published Anthropic’s official position On Sunday, he broke his silence on the lightweight models, which led to accusations that the company wanted to ban AI in lightweight to protect its business. “Anthropic has never advocated banning overweight models.“Amodei wrote.”Open weight models without dangerous capabilities are public goods.” The post comes after Nvidia’s Jensen Huang and dozens of tech companies signed an open letter supporting open weights and US officials considered banning Chinese open weight models.
Amodei listed three measures he supports instead of a ban. First, the introduction of chip export controls and “rampant smuggling” used to bring advanced chips to China, because scaling laws without US chips prevent China from training models more powerful than American models. Second, to stop industrial-scale distillation operations that allow Chinese labs to build capable models cheaper than training them from scratch. Third, mandatory safety testing for all sufficiently capable models, open and closed, regardless of model of origin. is completely exempted.
In an open letter backed by Nvidia, Amodei agreed that open weights expand access and competition, but agreed that they help defenders more than attackers. He pointed to biological weapons as the starkest example: a sufficiently skilled model can quickly weaponize a pandemic-level virus using widely available materials, whereas defense against such agents takes years. TNW reported last week that Anthropic’s silence on the open weights letter was notable. as the company that suffered the most direct commercial damage from distillation. This post is the answer.
The distillation point is the most commercially loaded. Anthropic accused Alibaba’s Gwen lab of running its biggest distillation campaign against Clod.It uses 25,000 fake accounts for 29 million exchanges. Amodei admitted that the fight against distillation “difficult” because accounts can often only be determined after significant distillation has occurred. He called for policy intervention rather than relying on any one company’s implementation. The position is carefully constructed: Anthropic is not against open weights, but against open weights stolen from their closed models, trained on smuggled chips and released without security tests for simple Washington applications. narratives is the political question the article is written to answer.
