Anthropic的Fable 5出口管制僵局，NSA和Anthropic对模型安全看法打架，局势微妙。
Anthropic顶级安全团队飞往华盛顿，与特朗普政府就Claude Fable 5出口管制谈判，周一会议未达成协议。商务部长Howard Lutnick从G7峰会电话参与，Anthropic联合创始人Tom Brown和外部事务主管Sarah Heck主导讨论。核心分歧在于Fable 5的护栏能否被移除解锁更强大的Mythos能力，NSA认为可行，Anthropic认为风险被夸大。目前无下一步清晰计划。

Anthropic and the Trump administration wrapped up talks on Monday with no resolution - the export controls on Claude Fable 5 are still in place. No end in sight.
The company has spent days arguing that Washington's concerns about the model are overblown, a line it repeated to government researchers at the Commerce Department.
Commerce Secretary Howard Lutnick joined by phone from the G7 summit in Evian, France, while cyber director Sean Cairncross sat the meeting out.
On Anthropic's side, cofounder Tom Brown and external affairs head Sarah Heck led the discussions, with red-teaming chief Logan Graham and security researcher Nicholas Carlini flying to DC for the talks.
The core disagreement is whether Fable 5's guardrails can be stripped away to unlock the more powerful Mythos capabilities underneath, the NSA thinks yes, Anthropic thinks the risk is overstated.
For now there's no clear sense of what the next steps look like.
