Trump Administration Restores Anthropic's Claude Mythos 5 Access

The Trump administration has authorized Anthropic to restore access to its most advanced AI model, Claude Mythos 5, for a select group of government-approved organizations, reversing a national security order issued just two weeks earlier.

Commerce Secretary Howard Lutnick announced Friday that "appropriate safeguards are in place" to permit certain trusted partners to use the model. The decision follows intensive negotiations between the San Francisco-based AI company and federal officials over security concerns that prompted the original suspension.

Selective access for approved partners

More than 100 companies and institutions—many from the Fortune 500—have received clearance to access Mythos 5. Lutnick indicated the approved list could expand "at any time" as additional organizations meet government security requirements.

The Commerce Department's letter credited Anthropic with working collaboratively to "address risks associated with the covered models," noting these efforts "have yielded significant progress."

A second Anthropic model, Fable 5, remains offline. Designed for broader public use, Fable 5 is still subject to ongoing negotiations between the company and federal authorities.

Why it matters

The rapid reversal highlights the tension between AI safety concerns and commercial pressure from enterprise customers. By creating a tiered access system based on government vetting, the administration has established a precedent for controlling advanced AI deployment through partner approval rather than blanket restrictions. This approach could become a template for regulating future frontier models that raise national security questions.

Company response

Anthropie expressed satisfaction with the outcome in a statement: "We are pleased to see this progress. We're restoring access for these organizations quickly, and we're continuing to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again."

The original suspension order, issued in mid-June, cited unspecified national security concerns related to both Claude Mythos 5 and Fable 5. The two-week blackout period likely disrupted enterprise customers who had integrated the models into their operations.

The partial restoration suggests federal officials found a middle path between their security concerns and the commercial realities of cutting off access to cutting-edge AI capabilities that businesses increasingly depend on.

Details of the specific safeguards Anthropic implemented to satisfy government requirements were not disclosed. The Commerce Department has not indicated a timeline for potential broader access to Mythos 5 or resolution of the Fable 5 restrictions.
