内容总结：

美国人工智能公司Anthropic推出的两款主打网络安全的高性能模型“Mythos 5”与“Fable 5”因遭禁用而被迫下架两周后，特朗普政府近日立场有所松动。据Semafor和路透社报道，当局现允许Anthropic向超过100家美国特定政府机构及企业重新开放“Mythos 5”的使用权限，其中包括上述组织内的非美籍员工，甚至包括Anthropic自身的非美籍雇员——此前禁令曾明确禁止非美国公民访问该模型。

美国商务部长霍华德·卢特尼克在周五致函Anthropic首席计算官汤姆·布朗时表示：“我已确认，目前已具备充分的安全保障措施，可允许部分受信任合作伙伴访问‘克劳德·Mythos 5’模型。”不过，该指令并未涉及“Fable 5”模型的解禁问题。作为“Mythos 5”的衍生版本，“Fable 5”因声称具备更强防护能力，在禁令实施前已广泛发布数日。但两款模型随后因安全研究人员声称可轻松绕过其防护机制而遭全面撤回。目前Anthropic尚未就此置评。

Anthropic于周五在X平台公开发文承认进展：“自6月12日起，我们一直与美国政府密切合作，以恢复‘Claude Mythos 5’和‘Fable 5’的访问权限。今天，政府通知我们，可向运营及防御关键基础设施的美国机构重新部署我们最强的网络安全模型Mythos 5。我们正在迅速为这些机构恢复访问，并将继续与政府协作，扩大Mythos 5的权限范围，并推动Fable 5重新向公众开放。”

禁令实施两周后，导致Anthropic公司将其强大的网络安全模型Mythos 5和Fable 5从市场撤出的特朗普政府正软化立场。据Semafor和路透社报道，目前政府允许Anthropic向超过100家特定美国政府机构和企业提供Mythos 5，包括允许这些组织中的非美国雇员访问该模型。这份名单还包括Anthropic自身的非美国雇员——这些人原本被包含在禁止非美籍人员访问模型的初始禁令中。

根据Semafer获得的信函，商务部长霍华德·卢特尼克周五在致Anthropic首席计算官汤姆·布朗的信中写道："我已判定现有防护措施已到位，允许特定可信合作伙伴访问Claude Mythos 5模型。"显然，此次指令并未涉及Fable 5的发布。该模型是Mythos 5的版本，因据称具有更强防护能力，在禁令实施前数日曾广泛发布。在安全研究人员声称轻易绕过这些防护措施后，两款模型均被下架。Anthropic未立即回应我们的置评请求。

Anthropic周五在X平台发帖公开承认进展："自6月12日起，我们一直与美国政府密切合作，以恢复Claude Mythos 5和Fable 5的访问权限。今天，政府通知我们，我们最强大的网络安全模型Mythos 5可重新部署至一批运营和防御关键基础设施的美国组织。我们正迅速为这些组织恢复访问权限，并继续与政府合作扩大Mythos 5的访问范围，同时推动Fable 5重新面向公众开放。"

Two weeks into the ban that caused Anthropic to pull its powerful cybersecurity-oriented models, Mythos 5 and Fable 5, from the market, the Trump administration is softening its stance.
It is now allowing Anthropic to make Mythos 5 available to more than 100 specific U.S. government agencies and companies, including allowing the non-American employees at those organizations to access to the model, both Semafor and Reuters report. This list also includes Anthropic’s own non-American employees, who were included in the original ban that forbade non-Americans from accessing the models.
“I have determined that appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model,” Commerce Secretary Howard Lutnick wrote to Anthropic’s chief compute officer Tom Brown on Friday, according to the missive seen by Semafor.
Apparently, the administration did not address the release of Fable 5 in this directive. This is a version of Mythos 5 that was widely released a couple of days before the ban because it was said to have more protections. Both models were pulled after those guardrails were allegedly bypassed easily by security researchers. Anthropic did not immediately respond to our request for comment.
Anthropic on Friday publicly acknowledged the progress in a post on X, writing: “Since June 12, we’ve been working closely with the US government to restore access to Claude Mythos 5 and Fable 5. Today, the government notified us that Mythos 5, our strongest cybersecurity model, can be redeployed to a set of US organizations that operate and defend critical infrastructure. We’re restoring access for these organizations quickly, and we’re continuing to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again.”
