Frontier AI lab Anthropic, on Tuesday, said that the US Department of Commerce has lifted export restrictions imposed on two of its advanced AI models – Claude Fable 5 and Mythos 5. The move follows the government’s decision three weeks ago to require the Dario Amodei-led company to suspend access to the AI models over national security concerns.
The company took to its official X handle to announce that it will begin restoring access starting Wednesday, July 1, and will be sharing an update soon. “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 wrote in X, adding that it is grateful to its users for their patience and to all who worked with it on redeploying the models.

The US has beefed up its oversight of new AI model releases to detect potential threats amid growing concerns that advanced AI models could be misused by military and intelligence agencies in China, Russia and other countries.
The export control order was announced on June 12, following which the company had disabled access to Mythos 5 and Fable 5 models. However, on June 26, Reuters reported that the US government would allow Anthropic to redeploy Mythos 5 beginning June 28 to certain trusted US organisations.
