Trump administration restores access to Anthropic’s Fable and Mythos AI models after export-control review

Commerce Secretary Howard Lutnick said the Commerce Department lifted the restrictions placed on Anthropic’s newly released Fable and Mythos models, returning access just over two weeks after limits went into effect under U.S. export controls.

The Trump administration lifted restrictions on Anthropic’s newly released Fable and Mythos artificial intelligence models on Tuesday, restoring access a little more than two weeks after the Commerce Department imposed limits as part of U.S. export controls, according to Commerce Secretary Howard Lutnick.

Lutnick announced the change on X, saying the agency has “worked closely with Anthropic to analyze and approve” the models, including Fable 5, after the earlier restrictions were put in place. The announcement returned access to the models that had been constrained shortly after their release, The Hill reported.

The earlier restrictions were tied to U.S. export controls on the Anthropic models. While the reporting described the restrictions as export-control limits and noted that access had been restricted for just over two weeks, the announcement did not, in the available description, detail the specific technical findings or the regulatory steps taken to reach the reinstatement.

The episode highlights how the Commerce Department’s export-control framework can affect the timing of access to frontier AI systems. When restrictions are imposed, affected companies can face delays in providing model access, depending on how the controls apply to licensing and authorization pathways.

In Lutnick’s account, the agency’s decision followed an interlocking review process with Anthropic, described as analysis and approval work carried out after the restrictions took effect. Anthropic was the company directly involved, and the Commerce Department was the approving authority for the reinstatement described in the public announcement.

The practical effect of the administration’s action is that the models that were previously limited can again be used under the restored conditions. In the near term, questions for market participants and developers typically center on whether additional changes to export-control classifications or authorization requirements will follow, and how quickly the restored access takes effect for existing and new customers.

The timing also places the decision within an active period for U.S. AI export-control enforcement and review, where federal agencies can adjust access outcomes as more information becomes available about model capability and related compliance assessments.

Why It Matters

The decision underscores that U.S. export controls can quickly change a company’s ability to provide access to advanced AI models.
The administration’s stated approach centered on agency review and approval steps conducted with the company, shaping how future model authorizations may proceed.
The timeline of roughly two weeks between restriction and reinstatement shows how rapidly the regulatory outcome can shift during active export-control assessments.
For developers and customers, restored access can affect product integration timelines that depend on model availability and licensing conditions.
