Filesystem controls were another important architectural choice. We found that offering different file-mount modes helps to granularly control risk; Claude Cowork offers read-only, read-write, and read-write-no-delete.
行动建议：实现细粒度的文件系统访问控制，提供多种挂载模式（如只读、读写、读写但不删除）来精确控制风险。对于企业环境，还应实现路径允许列表功能，并通过MDM设置进行管理，防止符号链接等机制导致的边界逃逸。
export controls are leakier than previously understood
【洞察】「出口管制比之前理解的更加漏洞百出」——这句话是对整个西方 AI 地缘政治战略的严厉评价。更令人不安的是：如果走私渠道如此有效，那么比芯片更容易传输的「模型权重」和「训练技术」的扩散速度只会更快。硬件管制是可见的，但知识扩散是不可见的。Epoch AI 的数据与 Anthropic 指控中国公司「蒸馏」其模型放在一起读，呈现出一幅完整的算力与知识双重扩散图景。
our central estimate is around 660,000 H100-equivalents
【令人震惊的数字】走私流入中国的算力中位估算：66 万个 H100 等效——约占中国 AI 算力总量的三分之一。这个数字彻底改变了「出口管制正在有效阻断中国 AI 发展」的主流叙事。如果三分之一的算力来自走私，那么所有基于「中国无法获得先进芯片」假设的中美 AI 差距分析，都需要用这个修正系数重新计算。
We estimate that between 290,000 and 1.6 million H100-equivalents (H100e) were smuggled to China through 2025. Our median estimate of 660,000 H100e would be roughly a third of China's total compute.
大多数人认为美国出口管制能有效遏制中国获取先进AI芯片，但作者认为这些管制实际上导致大量芯片被走私到中国，走私数量可能与中国合法获取的芯片数量相当，这意味着出口管制的效果远不如预期。
These figures include Nvidia and AMD datacenter GPUs, Google TPUs, Amazon Trainium and Inferentia chips, and Huawei's AI chips. We estimate that these five categories encompass the vast majority of the world's dedicated AI computing power.
这个清单里藏着一个地缘政治炸弹：华为 AI 芯片被并列纳入「全球主要算力」统计。这意味着即便在出口管制和制裁下，华为的算力存量仍然大到不可忽视。中国 AI 算力的真实规模因此比西方媒体描述的更接近全球主流水平——「算力脱钩」的叙事可能严重低估了中国的实际积累。
Aortic dissection typically presents acutely with sudden, severe tearing chest or back pain, often described as lancinating in quality. [5-6] Approximately 50% of patients with thoracic aortic aneurysm may progress to dissection without timely intervention. [5] In contrast, thoracic aortic aneurysm is usually asymptomatic and discovered incidentally during physical examination or imaging for other indications. [5]

Like the nuclearprognosticators, Joy can see the juggernaut clearly. What he can’t see—which is precisely what makes his vision so scary—are any controls.
This observation is important in so many areas of life and research. It's not what you see in aggregate or on the surface, but the details below the surface which help to determine the second, third, and later-order effects.
it's not a technological advantage that you have it is a political advantage and an organizational advantage here in China The People's Bank the Central Bank of China controls the bankers in the United States the bankers control the central bank they own the central bank they created the Central Bank the Central Bank of the United States the Federal Reserve was created by JB Morgan it was not the other way around
