Chubby♨️@kimmonismus · X美国商务部致函Anthropic，要求对Fable 5与Mythos 5的“出口、再出口或国内转让”实施全球许可证管制，对象涵盖所有外国人士。基于冷战时期“视为出口”条款，外国人在美境内访问受控技术也被视为向国籍国出口。因Anthropic无法通过API实时区分用户国籍，唯一合规方案是向所有用户关闭模型。推主质疑美国政府短视，目前正与Anthropic寻求兼顾国家安全与可用的解决方案。引用认为，能力封锁将使开源模型更具吸引力，尤其利好中国开源，OpenAI与Anthropic将因此受损。
If you look at the documents again closely， it was never the US government's goal to take down Fable 5. It was simply a consequence of the impossibility of doing so for Anthropic. （i am re-reading the documents atm to get a even better picture of where we are heading）
The single most load-bearing document in the whole affair is the letter itself， obtained in full by Bloomberg four days after it landed. It is on Commerce Department letterhead， addressed to Anthropic CEO Dario Amodei， and its operative sentence is dry to the point of menace：
a license is now required for the "export， reexport， or transfer （in-country）" of Fable 5 and Mythos 5 "to all destinations worldwide and to all 'foreign persons' … wherever located." It threatens "prompt criminal and civil penalties" and stays in force "until superseded by a subsequent letter."
