美国商务部6月30日解除对Anthropic Claude Fable5及Mythos5模型的出口管制，7月1日全面恢复访问。此前因亚马逊研究员发现Fable5存在可被诱导提供网络攻击信息的漏洞，商务部于6月12日紧急限制该模型访问权限，禁令波及Anthropic外籍员工，导致模型下线近三周。
美国商务部近日解除对Anthropic旗下“Fable 5”和“Mythos 5”两款顶级AI大模型的出口管制，出口、再出口及境内技术转让均无需许可证。数周前白宫还曾因担忧技术泄露而强制该公司中止境外业务，此次政策大幅松绑，转向明显。
美国政府拟放宽限制，允许Anthropic恢复其核心AI模型Fable 5的访问权限，距出口管制令发布仅两周，被视为美方在AI技术管控与国家安全间的政策微调。此前6月12日出口管制令曾导致相关模型访问突然暂停。
美国AI公司Legion因政府禁令起诉联邦政府。由于Anthropic依出口管制规定禁止向外国公民提供最先进AI模型，导致Legion加拿大籍开发团队失去核心工具，公司称面临生存危机，已在华盛顿联邦法院提起诉讼。
