Day 10: Fable 5 and Mythos 5 still dark as Anthropic's free-trial clock runs out

The June 12 Commerce Department directive remains in force on the day Anthropic's complimentary access window was scheduled to close.

Day 10 of the Commerce Department directive, and Claude Fable 5 and Claude Mythos 5 remain dark to every Anthropic customer on the planet. The complimentary access window the company opened to soften the suspension was scheduled to close today. No public restoration timeline has been issued.

The directive landed June 12 at 5:21 p.m. ET, three days after Fable 5 and Mythos 5 went live to hundreds of millions of users. It cited national security authorities and ordered Anthropic to suspend access for any foreign national, inside or outside the United States, including non-citizen employees. Rather than segment by nationality, Anthropic pulled both models globally.

The company’s June 12 statement framed the trigger as a misunderstanding. The government had been shown a jailbreak prompting Fable 5 to read a specific codebase and flag software flaws, a capability Anthropic noted is available from publicly deployed models including OpenAI’s GPT-5.5. “We disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people,” the company wrote.

The politics are harder to dispute than the technology. CNBC reported on June 15 that Anthropic was preparing to meet with the Trump administration, with Amazon CEO Andy Jassy among the tech leaders escalating concerns to senior officials. Amazon has $8 billion already invested in Anthropic and up to $25 billion committed. That’s the financial weight now leaning on the dispute.

It’s not landing cleanly. Defense Secretary Pete Hegseth posted on X that “every passing day” proved the Pentagon was right to label Anthropic a supply chain risk in March, a designation Anthropic is contesting in federal court. Claude Opus 4.8 remains available; the flagship pair doesn’t.

The National Law Review advisory issued after the directive remains the operative guidance for customers: audit any API integration, internal tool, or autonomous agent routing to Fable 5 or Mythos 5 endpoints, and treat continued exposure as a deemed-export problem.

This is what a Commerce Department posture toward frontier AI looks like when the safety case and the security case point in opposite directions, and the security case wins by default.
