<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div><\/div>\n<\/div>\nAnthropic CEO Dario Amodei has sought to clarify his company\u2019s stance amid the growing industry debate over open-weight AI models. In a blog post, Amodei said that Anthropic has \u201cnever advocated for a ban on open-weights models,\u201d countering criticism that the firm is trying to exert excessive control over the future of artificial intelligence. His comments follow a coalition letter signed last week by Nvidia, Microsoft, Meta, Palantir and others, urging policymakers to avoid \u201cpremature restrictions\u201d on open-weight models. These models, which users can download, modify, and run independently, have become a flashpoint as Chinese startups dominate the space and US officials weigh possible restrictions.<\/p>\n In the post, Amodei said that the real focus should be on:<\/p>\n Anthropic previously warned the U.S. Senate about what it described as the \u201clargest known distillation attack\u201d carried out by China\u2019s Alibaba against its Claude models.Amodei further added that he agrees with parts of the coalition letter, including that open0weight models expand access, strengthen competition, and also gibe customers greater control. But he disagreed with the claims that open-0wright models inherently favor cyber defenders over attackers or make it easier to develop safeguards. \u201cProtectionist bans would not address my most serious national security concerns,\u201d Amodei wrote, making clear that Anthropic supports targeted legal frameworks rather than blanket restrictions. His remarks highlight the growing divide in the AI industry over how to balance openness, innovation, and security.<\/p>\n A post by Dario Amodei, Anthropic CEO<\/span>Over the last few days there has been a lot of discussion about open-weights models, especially those from China. Reports suggest that some US officials are considering banning the use of Chinese open-weights models by US companies. In response, many tech companies have signed a letter supporting open-weights models, and some people have even accused Anthropic of wanting to ban open-weights models as a means of protecting our business. Anyone who has read my past writing should know that I don\u2019t regard such bans as a useful measure, but let me state it clearly so that there is no doubt: Anthropic has never advocated for a ban on open-weights models.<\/span>Open-weights models that don\u2019t have dangerous capabilities are a public good: they don\u2019t cost anything besides the compute needed to run them, and they provide value to businesses, developers, and researchers.<\/span>Protectionist bans would not address my most serious national security concerns. Specifically, I am worried about two nightmare scenarios. I laid these out in my essay The Adolescence of Technology six months ago1, and have held these positions consistently for many years:<\/span>My primary concern is the risk that authoritarian governments\u2014not solely the Chinese Communist Party (CCP), although the CCP is clearly the most capable threat\u2014build AI models that are more powerful than those built by the US, and use them to achieve permanent military superiority or perpetrate incredibly deep repression of their own people. This concern is widely shared within the US government: Vice President <\/span>Vance<\/span> warned in Paris last year that \u201cauthoritarian regimes have stolen and used AI to strengthen their military, intelligence, and surveillance capabilities,\u201d and the Intelligence Community\u2019s 2026 Annual Threat Assessment found that \u201cother global powers\u2019 robust progress in AI is challenging US economic competitiveness and national security advantages.\u201d It is irrelevant whether these models are released with open weights, and certainly irrelevant whether they are used by US businesses. In fact, the most dangerous model may be one that is trained in secret and handed only to the People\u2019s Liberation Army for use in drones and the Ministry of State Security for surveillance and repression.<\/span>My secondary concern is the risk that powerful AI models may be misused to carry out cyberattacks or biological attacks, and may have serious alignment problems. Open-weights models\u2014it does not matter whether they come from China or anywhere else\u2014do potentially present a higher risk than closed models, because it is very difficult to apply guardrails to them or monitor their usage, and once weights are released they cannot be withdrawn2. But banning the use of these models by US businesses does nothing to address this risk, because bad actors are unlikely to be legitimate US businesses. It would protect US AI companies from competition, but that has never been my goal.<\/span>To address these concerns, I do support the following three measures, which I and Anthropic have consistently advocated for:<\/span>We should not sell powerful chips or chipmaking equipment to China, and we should crack down on the rampant smuggling and workarounds used to obtain access to such chips. China has limited domestic production capacity, and therefore, due to the scaling laws, cannot build more powerful models than the US without US chips. This is the most efficient and direct way to block threat #1, and by hampering the training of models that are out of reach of US law, it also indirectly helps with threat.<\/span>We should crack down on industrial-scale distillation operations. Distillation is a much more compute-efficient process than training models from scratch. It allows China to build much better models than its number of chips would ordinarily enable, and thus partially evade chip bans. Distillation does not allow the CCP to obtain equivalent or superior AI capabilities to the US, but it can bring the Chinese frontier to within a few months of the US frontier. It is true that many of the companies carrying out these operations release open-weights models\u2014but the open weights are far less relevant than the fact that the operations are backed by an authoritarian state seeking to overtake the US at the frontier. We should have policy interventions to deter this behavior. A blanket ban on open-weights models is neither the correct remedy nor something we have called for.<\/span>All sufficiently capable models, open and closed, should go through mandatory safety testing. The best way to address threat #2 is to just directly test models for cyber, biological, and alignment risks before release. I think this idea is actually close to a consensus: I have been heartened both that the <\/span>Trump<\/span> administration has moved in this direction in recent months, and by recent industry proposals that would apply such testing to the most capable models regardless of their country of origin or whether they are open or closed (while exempting less capable models, such as those from startups and academia, entirely). Whether open models do or don\u2019t pose an increased risk, and whether that risk can be mitigated, is something that should emerge from testing, rather than be decided in advance\u2014and there may be promising methods for improving the safety of open-weights models, including recent research from Anthropic on modular training strategies. Note that to be effective, testing would need to be global, which means even the CCP would need to be on board. I think this may actually be possible: as I wrote in The Adolescence of Technology, limited cooperation around preventing AI biological weapons may be possible because it is in China\u2019s interest too.<\/span>This brings me to the open letter. I agree with much of it: open weights expand access to the AI economy, they strengthen competition at least for some use cases, and they give customers greater control. Concerns about distillation should be addressed through targeted legal and commercial frameworks\u2014the same measure I described above. But I don\u2019t agree with the letter\u2019s assertions that open-weights models necessarily make it easier to develop safeguards or that broad access to capabilities necessarily helps defenders more than attackers. It seems at least as likely to me that the opposite will be true. For example, I worry that biology will have a strong attacker-defender asymmetry, where sufficiently capable models may be able to quickly weaponize pandemic-level viruses with widely available materials, whereas defense against these agents is a multi-year operational task in the best case (as we saw with Operation Warp Speed)5. Questions like this should be empirically answered by rigorous pre-release testing, not assumed in advance.<\/span>To summarize my and Anthropic\u2019s position, we have not and are not advocating for a ban on open-weights models as a category. We should instead focus on keeping powerful chips out of authoritarian hands, stopping industrial-scale distillation, and requiring safety testing of all sufficiently capable models, open and closed.<\/span><\/div>\n<\/div>\n Anthropic CEO Dario Amodei has sought to clarify his company\u2019s stance amid the growing industry debate over open-weight AI models.
