U.S. Commerce Ministry Explains Ban on Mythos 5 and Fable 5 AI Models by Threat to Russian and Chinese Intelligence

U.S. Commerce Minister Howard Lutnick stated that the ban on foreign access to the AI models Mythos 5 and Fable 5, introduced on Friday, July 10, 2026, was caused by the risk of them falling into the hands of intelligence structures of unfriendly countries, including Russia and China.

What was banned and when

This concerns the ban that took effect on Friday, July 10, 2026: from that moment, foreign citizens' access to the Mythos 5 and Fable 5 models was blocked. The decision was made by the U.S. Department of Commerce, and Lutnick publicly disclosed the department's motives for the first time after the ban took effect.

• The ban took effect on Friday, July 10, 2026
• The decision was made by the U.S. Department of Commerce
• The Commerce Minister Howard Lutnick publicly stated the motives
• The stated reason is the risk of the models being used by Russia and China's intelligence agencies
• The Mythos 5 and Fable 5 models were subject to restrictions

Why officials fear specifically these models

Lutnick linked the restriction to the possibility that the tools would fall into the hands of intelligence structures of countries unfriendly to the U.S. The formulation puts Mythos 5 and Fable 5 on the same level as dual-use technologies—those that are simultaneously useful in civilian tasks and represent interest for military or intelligence spheres. This logic has increasingly defined U.S. export restrictions on advanced AI models and chips for their training in recent years.

How this fits into the broader U.S. export control policy

Over the past several years, the U.S. Department of Commerce has consistently expanded the list of technologies subject to export restrictions on national security grounds: it started with advanced chips for AI training, then restrictions spread to equipment for their production, and now, judging by Lutnick's formulations, the department is ready to apply the same logic to the models themselves—that is, to the software product, not just the hardware on which it was trained.

• The department—U.S. Department of Commerce
• The formulation of risk—foreign intelligence agencies' access to advanced AI models
• Previously, similar restrictions already applied to chips for AI training and production equipment

How this case differs from previous restrictions

Export control over chips primarily affects hardware manufacturers—companies like NVIDIA that must coordinate supplies to certain countries. Restricting access to specific AI models is a different level of regulation: it targets not physical equipment but the software product of a laboratory, which potentially can be copied or distributed much easier than a batch of chips. That is precisely why Lutnick's formulation about the risk to intelligence agencies sounds like a signal that regulators now view the models themselves, not just the computational power for their training, as an object of strategic control.

What this means

A direct public explanation of the ban's motives by the Commerce Minister shows that U.S. authorities view advanced AI models not only as commercial but also as an intelligence asset—and are ready to introduce export restrictions on the same national security grounds that were previously applied to chips and weapons.
