The outcome
On June 30, 2026, the US Department of Commerce lifted the export controls that had suspended access to Fable 5 and Mythos 5, ending a roughly three-week standoff between Anthropic and the US government.

Before the full reversal, the government had already signaled a partial easing on June 26, allowing some companies and government agencies to regain access to Mythos 5.

The episode showed, in practice, how export controls — historically applied to hardware and military technology — can also be used on frontier AI models, a precedent other companies in the sector should watch closely.
