US Lifts Export Controls on Claude Fable 5 and Mythos 5
On June 30, 2026, the US Department of Commerce lifted the export controls that had forced Anthropic to pull Claude Fable 5 and Mythos 5 worldwide 18 days earlier.
The US Department of Commerce lifted the export controls on Claude Fable 5 and Claude Mythos 5 on June 30, 2026, clearing the way for Anthropic to restore the models after an 18-day suspension. Anthropic confirmed it had received notice and would begin restoring access the following day.
How the Controls Came and Went
The controls were applied on June 12, 2026 following a jailbreak report from Amazon researchers, forcing Anthropic to disable both models for every customer worldwide - the first time export-control authority had been used to pull a commercial AI model. On June 26, the government approved Mythos 5 access for US organizations, and on June 30 it lifted the controls entirely.
What Anthropic Said
In a statement posted to X, Anthropic said: "We've received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5. We'll begin restoring access tomorrow, and will share an update soon." The company thanked users for their patience and those who worked on resolving the matter.
What Came Next
Restoration followed on July 1, paired with a new safety classifier targeting the reported jailbreak. A move to usage-credit billing for Fable 5 on subscription plans took effect July 7.
