内容总结：

经过与特朗普政府长达两周的反复拉锯谈判，Anthropic公司的Mythos 5模型终于重新获得运行许可——至少对部分特定机构而言是如此。据《The Verge》获取的一封政府致Anthropic的信件显示，这一高端网络安全模型已有限恢复使用，但面向公众的Fable 5模型仍处于搁置状态，尚无明确的获批时间表。

美国商务部于6月26日向Anthropic联合创始人汤姆·布朗发出信函，商务部长霍华德·卢特尼克在信中表示，鉴于Anthropic近期已“与美国政府合作解决了”Mythos 5和Fable 5相关风险，因而对“许可要求进行了修订”。Anthropic发言人丹妮尔·吉列里向《The Verge》表示，公司已收到政府通知，“最强大的网络安全模型Mythos 5可重新部署给少数网络防御者和基础设施提供商”。她补充说：“我们正尽快为获批的提供商开通权限，恢复其访问权。我们对这一进展感到欣慰，并将继续与政府合作，扩大Mythos 5的访问范围，并争取让Fable 5重新面向公众开放。”

值得注意的是，美国政府并未解除两周前对Anthropic实施的出口管制指令——该指令禁止任何外籍人士（包括Anthropic自己的员工）访问这两款模型。政府仅对Mythos 5做出例外处理，批准特定机构访问，这与今天早些时候宣布的OpenAI GPT-5.6权限模式相同。根据信件内容，在此例外条款下，非美国籍的Anthropic员工以及获批机构中的非美国籍成员均可访问Mythos 5。

卢特尼克在信中写道：“这些努力已取得重大进展。此外，Anthropic已承诺与美国政府就（Mythos系列模型）的协议、标准和发布流程展开合作。鉴于这一进展……我已确定，目前已存在适当的安全保障措施，允许部分可信合作伙伴访问Claude Mythos 5模型。”

特朗普政府近期采取的逐案审查式监管环境正面临越来越大的压力，尤其是考虑到Anthropic竞争对手的网络安全模型性能不断提升，甚至在某些安全基准测试中已超越Anthropic。美国人工智能行业内部也普遍担忧：当顶级AI实验室被边缘化时，中国可能在该领域取得突破。此外，美国国家安全局等顶级政府部门此前也失去了对Mythos 5的访问权限。

目前，Anthropic已获得与OpenAI实质上相同的安排：以有限预览形式发布模型，仅限可信企业和美国政府等获批机构使用。两家AI实验室都希望尽快实现更广泛的可用性，包括企业合作和公共访问（如图Anthropic的Fable 5），但这最终取决于特朗普政府的决定。尽管包括AI实验室在内的各方都呼吁监管，但一些科技领袖近期达成共识：过去两周的做法并非理想的监管方式。

OpenAI在GPT-5.6发布博客中写道：“我们认为这种政府审批程序不应成为长期常态。它将最好的工具与需要它们的用户、开发者、企业、网络防御者和全球合作伙伴隔离开来。我们采取这一短期措施，是因为相信这是在未来几周内实现更广泛可用的最佳途径，同时我们将与政府合作制定网络安全行政命令框架，并为未来的模型发布建立可重复的流程。”

卢特尼克在给Anthropic的信中强调：“6月12日信函中所有其他要求仍然有效，直至另行通知。”他补充道：“若情况发生变化，我保留重新评估和调整（Mythos 5和Fable 5）许可要求范围的权利。”

经过与特朗普政府长达两周的波折谈判，Anthropic 的 Mythos 5 终于重新上线——至少对部分指定机构是如此。根据《The Verge》获得的一封政府致 Anthropic 的信件，这款模型已获准有限恢复使用。然而，面向公众的 Mythos 级模型 Fable 5 似乎仍处于悬而未决的状态，目前尚无明确的发布协议时间表。

Anthropic 的 Mythos 5 回归
特朗普政府批准了一批特定用户，但 Fable 5 仍然遥遥无期。

这封日期为6月26日的信函由商务部长霍华德·卢特尼克发送给近期主导谈判的Anthropic联合创始人汤姆·布朗，信中表示，基于Anthropic近期“与美国政府合作应对”与Mythos 5和Fable 5相关的风险，已对“许可要求进行了修订”。

Anthropic 发言人丹妮尔·吉列里在一份声明中告诉《The Verge》，公司“已收到美国政府通知，我们最强的网络安全模型 Mythos 5 可重新部署给一小批网络防御者和基础设施提供商。”她补充道：“我们正在努力配置获批准的供应商，并尽快恢复他们对 Mythos 5 的访问权限。我们乐见这一进展，并将继续与政府合作，扩大 Mythos 5 的访问范围，并让 Fable 5 重新面向公众开放。”

美国政府并未撤销两周前对 Anthropic 实施的出口管制指令，该指令禁止任何外国公民（包括 Anthropic 自己的员工）访问这两款模型。相反，政府基本上为 Mythos 5 开了绿灯，以批准特定机构访问的方式为其破例——这与今日早些时候宣布的 OpenAI 的 GPT-5.6 处理方式相同。根据信函内容，在此例外情况下，非美国国籍的 Anthropic 员工以及获批机构中的非美国籍成员，均可获得 Mythos 5 的访问权限。

“这些努力已取得显著进展，”卢特尼克写道。“此外，Anthropic 已承诺与美国政府合作，制定 [Mythos 级模型] 的相关协议、标准及发布流程。鉴于这一进展……我已认定，已建立适当的安全保障措施，允许某些值得信赖的合作伙伴访问 Claude Mythos 5 模型。”

特朗普政府近期采取的逐案式监管环境正面临越来越大的变革压力，尤其是因为 Anthropic 竞争对手的网络安全模型持续优化，甚至在一些网络安全基准测试上已反超其水平。美国 AI 产业内部的压力也在积聚，尤其是在顶级美国 AI 实验室被边缘化之际，人们担忧中国可能取得 AI 进展。此外，美国国家安全局等顶级政府部门已失去对 Mythos 5 的访问权限。

如今，Anthropic 获得的待遇与 OpenAI 基本相同：以有限预览形式发布模型，仅供获批机构使用，例如受信任的企业及美国政府本身。两家 AI 实验室都希望尽快实现更广泛的可用性，无论是面向企业合作还是公众访问（如 Anthropic 的 Fable 5），但这最终取决于特朗普政府。尽管包括 AI 实验室在内的许多方面都呼吁进行 AI 监管，但当前一些科技领袖的共识是，过去两周的做法并非正途。

事实上，OpenAI 在公司的 GPT-5.6 博客文章中写道：“我们认为这种政府访问审批程序不应成为长期常态。它使最优秀的工具无法触达需要它们的用户、开发者、企业、网络防御者及全球合作伙伴。我们采取这一短期措施，是因为相信这是在未来几周内实现更广泛可用性的最佳途径，同时我们将与政府合作，制定网络安全行政令框架及未来模型发布的可持续流程。”

卢特尼克在致 Anthropic 的信中写道：“6月12日信函中的所有其他要求继续有效，直至另行通知。”他补充道：“我保留根据情况变化重新评估并调整 [Mythos 5 和 Fable 5] 许可要求范围的权利。”

After a rollercoaster negotiation process with the Trump administration that dragged on for two weeks, Anthropic’s Mythos 5 is finally back in action — at least, somewhat, for a select group of organizations, according to a letter from the government to Anthropic that was viewed by The Verge. Fable 5, however — the public-facing Mythos-class model — appears to still be in limbo, with no apparent timeline for a rollout agreement.
Anthropic’s Mythos 5 is back
The Trump administration approved a select group of users, but Fable 5 is still nowhere in sight.

The Trump administration approved a select group of users, but Fable 5 is still nowhere in sight.
The letter, dated June 26th and sent by Commerce Secretary Howard Lutnick to Anthropic co-founder Tom Brown, who had been recently leading negotiations, states that there’s been a “revision to the license requirements” based on the fact that Anthropic has recently “worked with the U.S. government to address risks” associated with Mythos 5 and Fable 5.
Anthropic spokesperson Danielle Ghiglieri told The Verge in a statement that the company had “received notice from the US government that Mythos 5, our strongest cybersecurity model, can be redeployed to a small group of cyber defenders and infrastructure providers.” She added, “We are working to provision the approved set of providers and restore their access to Mythos 5 as quickly as possible. We are pleased to see this progress and continue to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again.”
The US government did not lift the export control directive it hit Anthropic with two weeks ago, which barred any foreign national from accessing either model (including Anthropic’s own employees). Instead, the government essentially made an exception for Mythos 5, approving a select group of organizations for access the same way it did for OpenAI’s GPT-5.6, announced earlier today. Under this exception, Anthropic employees who aren’t US nationals and members of the approved organizations who aren’t US nationals are all greenlit to access Mythos 5, according to the letter.
“These efforts have yielded significant progress,” Lutnick wrote. “In addition, Anthropic has committed to work with the U.S. government on protocols and standards and releases for [Mythos-class models]. In light of this progress ... I have determined that appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model.”
Pressure has been building on the Trump administration to make a change in the case-by-case type of regulatory environment it recently adopted, especially as Anthropic’s competitors’ cybersecurity-focused models kept getting better and better — and even pulling ahead of it on some cybersecurity-focused benchmarks. Pressure was also building within the US AI industry, particularly fears about the AI advancements China could make while top US AI labs were sidelined. Plus, there was the fact that top US government departments, like the National Security Agency, had lost access to Mythos 5.
Now, Anthropic has essentially the same deal OpenAI has: Release the model in a limited preview setting, for approved organizations only, such as trusted enterprises and the US government itself. Both AI labs hope that more general availability comes soon, both for enterprise deals and for public access (like with Anthropic’s Fable 5), but it’ll be ultimately up to the Trump administration. Though many have called for AI regulation, including AI labs themselves, a current consensus among some tech leaders is that the past two weeks haven’t been the way to do it.
In fact, OpenAI wrote in the company’s GPT-5.6 blog post, “We don’t believe this kind of government access process should become the long-term default. It keeps the best tools from users, developers, enterprises, cyber defenders, and global partners who need them. We are taking this short-term step because we believe it is the strongest path to broader availability in the coming weeks, while we work with the Administration to develop the cyber Executive Order framework and a repeatable process for future model releases.”
Lutnick wrote in his letter to Anthropic, “All other requirements of the June 12 letter remain in effect until further notice.” He added, “I reserve the right to reevaluate and adjust the scope of license requirements on [Mythos 5 and Fable 5], should circumstances change.”
