Brief

Anthropic says the US government on June 13, 2026 issued an export-control directive that bars any foreign national — inside or outside the US, including foreign‑national employees — from accessing Fable 5 and Mythos 5. To comply, Anthropic abruptly disabled those two models for all customers while keeping other Claude models available and working to restore access.

On June 13, 2026 the US government issued an export-control directive suspending access to Anthropic's Fable 5 and Mythos 5 for any foreign national worldwide, explicitly including foreign‑national Anthropic employees.

Key details

  • Anthropic says it has abruptly disabled Fable 5 and Mythos 5 for all customers to comply; access to other Claude models is unaffected and the company is working to restore access, calling the directive a misunderstanding.
Source evidence

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.
