US Lifts Export Controls on Anthropic’s Claude Fable 5 and Mythos 5 Models

The United States just lifted export controls on Anthropic’s Claude Fable 5 and Mythos 5. The Commerce Department cleared both models on June 30, paving the way for a swift restoration of full global access starting July 1.

The resolution ends nearly three weeks of tense negotiations between Anthropic and the White House.

What the Lifted Export Controls Actually Mean

An export control is a US rule that restricts who can access sensitive technology, including advanced AI models, for national security reasons. The Commerce Department imposed one on Claude Fable 5 and Mythos 5 shortly after the models launched. It has now been formally reversed.

The original directive landed on June 12, just three days after the models went live on June 9. Furthermore, it cited national security concerns reportedly linked to potential jailbreaks of the model. As a result, Anthropic suspended access for foreign nationals worldwide across every product surface.

The rule caused immediate operational chaos. Segmenting users by nationality in real time proved impossible in practice. Consequently, Anthropic took both models entirely offline for customers on Claude.ai, the API, AWS Bedrock, and other partner platforms until the situation could be resolved.

The company confirmed the reversal directly. “We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5. We’ll begin restoring access tomorrow, and will share an update soon,” Anthropic posted on June 30.

Why Claude Fable 5 and Mythos 5 Matter So Much

Claude Fable 5 is Anthropic’s most capable, widely available model. It is built on the powerful Mythos-class architecture but ships with enhanced safeguards for general use. Furthermore, it excels at demanding reasoning tasks, long-horizon agentic work, software engineering, and advanced vision capabilities.

Mythos 5 targets more sensitive workloads. The model shares the same underlying architecture but includes enhanced safeguards for cybersecurity applications. Moreover, access was originally reserved for trusted partners through Project Glasswing across high-stakes government and enterprise deployments.

Over the past two weeks, we have worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America’s leadership in AI. https://t.co/PtVJWyQ9kH

Pricing keeps both models competitive across the industry. Anthropic charges $10 per million input tokens and $50 per million output tokens. Additionally, built-in classifiers automatically route high-risk queries to safer fallbacks, especially on cybersecurity and biology-related tasks across every product surface.

The resolution highlights a broader shift in the AI industry. Anthropic held intensive talks with Commerce Department and White House officials throughout the standoff. As a result, the swift lifting signals both effective advocacy and a maturing regulatory framework for advanced AI systems nationwide.
