Anthropic announced Tuesday that the U.S. Commerce Department has removed export controls placed on its Claude Fable 5 and Mythos 5 artificial intelligence models — a reversal that comes less than three weeks after the company was directed to cut off access to those systems due to national security concerns.
“We’ll begin restoring access tomorrow,” Anthropic stated in a post on X.
The company had abruptly shut down both the Mythos 5 and Fable 5 models after receiving the export-control order on June 12. Then, last Friday, Anthropic disclosed that the federal government had permitted it to make its Claude Mythos 5 model available to select “trusted” U.S. organizations — a partial rollback of the original restrictions.
U.S. Commerce Secretary Howard Lutnick addressed the full reversal in a post on X, saying: “Over the past two weeks, we have worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America’s leadership in AI.”
The federal government has been increasing its scrutiny of new AI model releases, seeking to identify potential threats posed by the powerful systems that are fueling the AI industry’s rapid growth and attracting enormous investment. However, the process of determining which organizations can gain access to these models has sparked pushback.
OpenAI CEO Sam Altman weighed in last week on X, saying that thorough safety testing “is not a bad idea. I just don’t like the idea of the government picking the customers.”
OpenAI, the company behind ChatGPT, also delayed the full public rollout of its GPT-5.6 model at the request of the U.S. government, initially limiting availability to a small group of vetted partners.
