Anthropic to restore Claude Fable 5 after US export controls lifted
Following weeks of negotiations with the Trump administration, Anthropic is allowed to bring back its consumer-facing AI model Claude Fable 5, which was sidelined in early June due to export restrictions.
Anthropic announced it will begin restoring access to its Claude Fable 5 model tomorrow, after the Department of Commerce lifted export controls on both Fable 5 and its underlying Mythos 5 technology. The decision comes after weeks of talks with the Trump administration.
In early June, Anthropic sidelined Fable 5 following a Friday evening ultimatum from the Trump administration, which cited concerns over potential jailbreak vulnerabilities. The government imposed an export control directive barring any foreign national—including non-US members of enterprise client companies and even some of Anthropic's own employees—from using either Mythos 5 or Fable 5.
Earlier, the Trump administration had greenlit the return of Mythos 5, but only for a pre-approved list of organizations. Now, non-US members of those organizations, as well as Anthropic's foreign national employees, are allowed access. The move came shortly after OpenAI unveiled GPT-5.6 under similar rules: a staggered rollout initially limited to a pre-approved list of organizations and government departments.
The initial export control directive hit Anthropic at a challenging time, as the company is preparing for an initial public offering (IPO) and has been feuding with the government for months over a supply chain risk designation.
