Washington, 01 July 2026

The US government has lifted the export controls imposed in mid-June on the AI models Fable 5 and Mythos 5 from the company Anthropic after more than two weeks, prompting Anthropic to announce it would restore access to the programs immediately.

The US company stated on X that the Department of Commerce had ended the export controls on "Claude Fable 5" and "Mythos 5." "Man werde sofort damit beginnen, den Zugang zu den KI-Modellen wiederherzustellen," Anthropic assured. Previously, Anthropic had been forced to completely block the models in order to comply with the government's order that foreign nationals were not to be granted access; the company's own employees of foreign nationality were also affected.

The government's action was triggered by warnings that security precautions designed to prevent, for example, the use of Fable 5 to search for software vulnerabilities could be circumvented. One concern from the outset was that such an AI could become a dangerous cyber weapon in the wrong hands. On 12 June, the US government had imposed sweeping export controls on the powerful models, citing national security concerns. The systems were then taken completely offline.
