The ‘Mythos’ crisis escalates: US restrictions, European investigations, and negotiations between Anthropic and the White House

Anthropic, the American company developing advanced artificial intelligence models, is experiencing one of the biggest regulatory crises in its history, following the U.S. government’s decision to impose restrictions on two of its latest models, “Claude Mythos 5” and “Claude Fable 5,” amid growing security concerns about the possibility of foreign entities—led by China—gaining access to these advanced technologies.

American media reports revealed that the White House’s concerns over the possibility that parties linked to China might gain access to the “Mythos” model were among the main reasons that prompted the U.S. administration to impose strict restrictions on the model’s use and export. U.S. authorities fear that foreign entities could benefit from the model’s advanced capabilities or attempt to reverse-engineer it to develop competing artificial intelligence systems.

In the wake of the decision, Anthropic announced the suspension of access to the two models “Mythos 5” and “Fable 5” in compliance with U.S. government directives related to national security. This step is considered one of the most stringent measures the United States has taken to date against advanced AI models.

The crisis was not limited to the United States, as the European Commission began studying the repercussions of Anthropic’s decision to restrict access to its most advanced models, particularly with regard to international cooperation and AI safety research. European bodies are seeking to assess the impact of these restrictions on efforts in oversight, regulation, and the joint development of advanced technologies.

In an effort to contain the crisis, Anthropic entered into direct talks with White House officials to find a solution that would allow the resumption of operating the models or easing the restrictions imposed on them. Reports indicate that the company’s senior technical officials held meetings and consultations with the U.S. administration over the past few days to discuss security concerns and the possibility of reaching a mechanism that balances innovation with safeguarding national security.

These developments highlight the growing challenges facing the artificial intelligence sector globally, as advanced models are increasingly being treated as strategic technologies with security and geopolitical dimensions, amid intense competition between the United States and China for leadership in this field.

Observers believe that the “Mythos” case could set an important precedent in how governments deal with the next generation of highly capable artificial intelligence models, especially amid growing concerns related to cybersecurity and the transfer of sensitive technology across borders.
