Anthropic wins clearance to restore Claude Fable 5 after Trump talks

Anthropic has secured government approval to bring Claude Fable 5 back into service after an extended shutdown. The company announced it will begin restoring user access tomorrow, marking the end of a dispute with the Trump administration over export controls on advanced AI models.

What happened#

The Fable 5 model was taken offline in early June following a sudden directive from the Trump administration. The government imposed export restrictions citing concerns about potential security vulnerabilities and jailbreaks, effectively barring non-U.S. citizens—including international staff at Anthropic itself and foreign employees of enterprise clients—from accessing both Fable 5 and its underlying Mythos 5 model.

The path to reinstatement#

The Department of Commerce has now lifted the export controls. A post from Anthropic on X confirmed the decision and outlined plans to resume service.

Unlike a blanket restoration, the approval comes with guardrails: Mythos 5 remains available only to organizations on a pre-approved government list. This mirrors the rollout strategy the Trump administration imposed on OpenAI's GPT-5.6 model, which debuted under similarly staged access conditions.

Why the timing matters#

The export controls arrived during a particularly sensitive period for Anthropic—the company is preparing for an initial public offering while navigating months of tension with the Pentagon over a supply chain risk designation. The sudden constraints disrupted product launches the company had spent weeks promoting and created operational friction across its international workforce.
