PARAGRAPH 1 — The Core News 核心新闻
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
美国政府援引国家安全权限，发布了一项出口管制指令，要求暂停所有外国公民（无论在美国境内还是境外，包括Anthropic的外国籍员工）对 Fable 5 和 Mythos 5 的访问。该命令的实际影响是，我们必须突然为所有客户禁用 Fable 5 和 Mythos 5 以确保合规。
PARAGRAPH 2 — What Happened 发生了什么
We received the directive from the government today at 5:21pm (ET). The letter did not provide specific details of its national security concern. Our understanding is that the government believes it has become aware of a method of bypassing, or "jailbreaking" Fable 5. We reviewed a demonstration of this specific technique being used to identify a small number of previously known, minor vulnerabilities. These vulnerabilities all appear relatively simple, and we have found that other publicly-available models are able to discover them as well without requiring a bypass.
我们今天下午5:21（东部时间）收到了政府的指令。该信函未提供其国家安全关切的具体细节。据我们理解，政府相信其已知晓一种绕过或"越狱" Fable 5 的方法。我们审查了该特定技术被用于识别少量此前已知的、轻微漏洞的演示。这些漏洞都显得相对简单，而且我们发现其他公开可用的模型也能在不需要绕过措施的情况下发现它们。
PARAGRAPH 3 — Anthropic's Defense 公司的辩护
We stand by this defense in depth strategy. It reduces the risks posed by Fable, making them comparable to the risks of existing models already deployed across the industry. We have not even received a disclosure of a concerning non-universal potential jailbreak that led to a harmful result. The potential jailbreaks that have been disclosed to us are either entirely benign responses or are minor findings that provide no Mythos-specific uplift.
我们坚持纵深防御策略。它降低了 Fable 带来的风险，使其与行业中已部署的现有模型的风险相当。我们甚至没有收到任何导致有害结果的、令人担忧的非通用潜在越狱披露。已向我们披露的潜在越狱要么完全是无害的回应，要么是不提供 Mythos 特有能力增强的轻微发现。
PARAGRAPH 4 — Closing Position 收尾立场
We are complying with the government's legal directive and are removing access to Fable 5 and Mythos 5 for all users. However, we disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people. If this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers.
我们正在遵从政府的法律指令，并为所有用户移除对 Fable 5 和 Mythos 5 的访问。然而，我们不同意发现一个狭隘的潜在越狱应当成为召回一个已部署给数亿用户的商业模型的理由。如果这一标准在全行业适用，我们认为它将基本上停止所有前沿模型提供商的新模型部署。

Key Grammar Patterns

这些句式在正式英语写作（邮件、报告、声明）中非常实用。

Pattern 1: "citing + noun" 分词短语作状语
用 "citing"（援引）开头的分词短语来说明原因或依据。这是正式写作中非常高级的表达方式，比 "because of" 更精炼。
Citing national security authorities, the US government has issued an export control directive.
援引国家安全权限，美国政府发布了出口管制指令。
仿写练习：
Citing poor quarterly earnings, the company _______ (宣布裁员).
参考答案：Citing poor quarterly earnings, the company announced layoffs.
Pattern 2: "whether... or..." 无论……还是……
表示"无论哪种情况都适用"，在正式文件中常见。注意这里不用 "no matter"，"whether...or..." 更正式。
...by any foreign national, whether inside or outside the United States.
……任何外国公民，无论在美国境内还是境外。
仿写练习：
This policy applies to all employees, whether _______ (全职还是兼职).
参考答案：...whether full-time or part-time.
Pattern 3: "The net effect of X is that..." X的实际影响是……
一种将复杂情况简化为一个结论的高级表达。"net effect" 是"最终/净影响"，常用于商业和政策讨论。
The net effect of this order is that we must abruptly disable Fable 5 for all our customers.
该命令的实际影响是我们必须突然为所有客户禁用 Fable 5。
仿写练习：
The net effect of the new tariffs is that _______ (消费者将支付更高价格).
参考答案：...is that consumers will pay higher prices.
Pattern 4: "We disagree that X should be cause for Y" 我们不同意X应成为Y的理由
一种礼貌但坚定的反对表达。在职场邮件中表达不同意见时非常实用。"cause for" 后接动名词（-ing形式）。
We disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model.
我们不同意发现一个狭隘的潜在越狱应当成为召回商业模型的理由。
仿写练习：
We disagree that a single incident should be cause for _______ (修改整个政策).
参考答案：...should be cause for revising the entire policy.
Pattern 5: "If this standard was applied..., it would..." 虚拟语气
这是与现在事实相反的虚拟语气（Second Conditional），用来表达假设情况。结构：If + 过去式, ... would + 动词原形。
If this standard was applied across the industry, we believe it would essentially halt all new model deployments.
如果这一标准在全行业适用，我们认为它将基本上停止所有新模型部署。
仿写练习：
If every minor bug was treated as critical, it would _______ (使开发流程瘫痪).
参考答案：...it would paralyze the development process.
