CNN reported on June 30, 2026 that the US government has lifted export controls on Anthropic's most advanced AI models.

What Anthropic announced

  • Anthropic said in a statement Tuesday evening: "We've received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5."
  • The company added: "We'll begin restoring access tomorrow, and will share an update soon."

Commerce Secretary Lutnick's statement

  • The announcement came shortly after Commerce Secretary Howard Lutnick posted on social media about lifting export controls on Fable.
  • "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," Lutnick said in a post on X.

How CNN frames Fable and Mythos

  • Fable is a version of Anthropic's most advanced AI model, known as Mythos, but with extra guardrails to make it suitable for public use.
  • CNN says the export ban and subsequent negotiations highlighted continued regulatory uncertainty around AI even as the technology advances beyond current rules.

Background on the export ban CNN recounts

  • Earlier in the month, the government said a trusted partner—which CNN learned was Amazon—found a jailbreak, or a way to get around Fable's guardrails.
  • Anthropic said at the time the jailbreaks were "simple" and that "other publicly-available models" had similar work-arounds.
  • A source at Anthropic told CNN the company implemented a new safeguard to directly address and block the vulnerabilities reported by Amazon.
  • The Commerce Department then issued an export ban requiring the company to suspend all use by foreign nationals—including Anthropic employees themselves.
  • Anthropic disabled customer access to both Mythos and Fable as a result.

Partial Mythos release before the lift

  • After Anthropic and the government worked together to address cyber risks, the Commerce Department last week allowed Anthropic to release Mythos to select government-approved entities.
  • Experts told CNN Mythos can exploit cybersecurity vulnerabilities at an unprecedented pace.
  • Anthropic limited its release to a group of key partners "to secure the world's most critical software," CNN reported.

OpenAI context in the same piece

  • CNN also notes the White House requested OpenAI limit the release of its upcoming GPT 5.6 model to a small number of government-approved partners because of its advanced capabilities.
  • OpenAI said at the time they "don't believe this kind of government access process should become the long-term default."
