Anthropic disabled access to its newly released Mythos 5 and Fable 5 AI models following a U.S. government directive [1].
This move signals an intensifying effort by federal authorities to restrict the flow of advanced artificial intelligence capabilities to foreign entities. By intervening in the availability of top-tier models, the government is prioritizing national security over the open commercial distribution of AI technology.
The company pulled access to the two models [1] on June 12, 2024 [2]. The directive was issued based on national security and export control concerns specifically regarding foreign-national access to the systems [3].
Reports on the scope of the restriction vary. Some accounts indicate the order was designed to prevent any foreign national from accessing the models [4]. Other reports said that the company disabled the models for all users [5].
While some reports attribute the directive to the Trump administration [1], other accounts describe it more broadly as a U.S. government order [2]. The company has not provided further public details regarding the specific technical triggers that led to the security concerns.
The suspension of Mythos 5 and Fable 5 represents a rare instance of a private AI firm removing a product from the market entirely due to government pressure. This creates a precedent for how the U.S. may manage the proliferation of high-reasoning AI models in a competitive global environment.

The suspension of these models highlights the growing tension between the rapid pace of AI innovation and the requirements of national security. By treating large language models as sensitive exports, the U.S. government is treating AI software more like physical weaponry or dual-use hardware, which could lead to a fragmented global AI landscape where access is determined by citizenship and geopolitical alliances.
