US Close to Allowing Anthropic to Restore Fable 5 AI Model After Export Control Ban

The Trump administration is nearing a decision to let Anthropic restore its Fable 5 AI model after a sudden export control ban. The move follows a partial reversal for the related Mythos 5 model, but questions remain about new restrictions and national security implications.

June 27, 2026, (Inside AI) — The Trump administration is close to allowing Anthropic to restore access to its Fable 5 model, Axios reported on Saturday, citing a source close to the situation. The move would partially reverse a June 12 export control order that forced the company to abruptly disable its most advanced AI models for all users.

Insiders expect the administration's limits on Fable 5 could be lifted as soon as this coming week, the report said. Conversations between the parties are expected to continue over the weekend, and Anthropic expects to restore Fable access soon, the report added, citing a second source.

Reuters could not immediately confirm the report. Anthropic and the White House did not immediately respond to requests for comment.

This development follows a partial reversal on Friday, when the U.S. government allowed Anthropic to release its Claude Mythos 5 artificial intelligence model to some "trusted" U.S. organizations. That order had been suspended two weeks ago over national security risks.

Both Fable 5 and Mythos 5 use the same underlying AI model, but Fable 5 is designed for wide public availability, whereas Mythos 5 operates with fewer safeguards. The distinction is critical: Fable 5 represents Anthropic's most capable model intended for general release, while Mythos 5 is a higher-risk variant with relaxed constraints.

A source familiar with the directive told Reuters that the government is moving towards allowing Anthropic to release Fable soon, although a timeline is unclear. The source did not specify what conditions or restrictions might accompany the restoration.

The original June 12 export control order shocked the AI industry. Anthropic disabled Fable 5 and Mythos 5 globally, without prior warning, citing compliance with the government directive. The order's suddenness raised questions about the scope of U.S. export controls on AI models and the balance between innovation and national security.

Anthropic had positioned Fable 5 as a breakthrough in safe, steerable AI. Its abrupt removal left enterprise customers and developers scrambling for alternatives. The partial restoration for Mythos 5, limited to vetted U.S. entities, signaled a possible thaw, but the fate of Fable 5 remained uncertain until this weekend's report.

The administration's apparent shift may reflect pressure from industry groups and lawmakers who argued that broad restrictions harm U.S. competitiveness. Critics contend that export controls on AI models are blunt instruments that stifle innovation without addressing underlying security risks. Proponents insist that advanced AI requires tight oversight to prevent misuse by adversaries.

Anthropic has not disclosed the specific national security concerns cited by the government. The company's transparency reports previously emphasized voluntary safety testing and red-teaming. The export control order suggested that those measures were deemed insufficient by regulators.

The timeline for Fable 5's return remains fluid. If restored, it would likely come with new usage restrictions or monitoring requirements. The AI community will watch closely for details on how the model's capabilities might be constrained compared to its pre-ban state.
