Anthropic suspends access to new Claude models after U.S. export control directive
Anthropic is facing a sharper form of federal scrutiny after years of publicly backing tighter artificial intelligence safeguards. The restriction targets the company’s latest Claude models, Fable 5 and Mythos 5, and bars access by foreign nationals inside and outside the U.S., including some employees.
Highlights
- Anthropic suspended access to Fable 5 and Mythos 5 models for all foreign nationals after receiving a U.S. export control directive citing national security.
- Both Anthropic and administration officials are engaging in urgent talks in Washington, D.C., to resolve the suspension, which the company calls a misunderstanding.
- The Wall Street Journal links the directive to Amazon's reported security concerns regarding Fable 5, signaling a shift from voluntary to mandatory U.S. AI oversight.
Directive targets Anthropic’s latest AI releases
As reported by CNBC, Anthropic said on Friday that it received an export control directive ordering the company to suspend access to Fable 5 and Mythos 5 for any foreign national, whether inside or outside the U.S. The company said the administration cited national security authorities but did not specify the underlying concern.The action comes days after Chief Executive Dario Amodei publishes an essay calling for more serious and binding AI regulation, including mechanisms to block models judged unsafe. Anthropic says it supports statutory oversight that is transparent, fair, clear and grounded in technical facts, but argues the current directive does not meet those standards.
The company describes the disruption as a misunderstanding and says senior employees travel to Washington, D.C., on Monday to meet Trump administration officials. Anthropic tells CNBC that both sides are working quickly to resolve the matter.
Policy and market implications for the AI sector
Anthropic has promoted AI safety since its 2021 split from OpenAI and has supported regulation at both state and federal levels. It also praises an AI executive order signed by President Donald Trump earlier this month as an important step, although the order mainly asks companies on a voluntary basis to share models with the federal government for capability assessments before full release.There is no indication the suspension is directly tied to that executive order. The Wall Street Journal reports that the move is prompted by conversations between Amazon Chief Executive Andy Jassy and U.S. officials, including Treasury Secretary Scott Bessent, after Amazon researchers allegedly used prompts that led Fable 5 to provide information that could aid cyberattacks.
Daniel Remler, a senior fellow at the Center for a New American Security, says the directive appears mandatory because it suggests consequences for noncompliance. The episode raises the prospect that U.S. oversight of advanced AI models is moving beyond voluntary review frameworks toward direct operational restrictions for companies developing security-sensitive systems.
In our earlier coverage of the G7’s Evian discussions on frontier AI governance, we outlined how governments and top AI executives were focusing on sovereignty, infrastructure, and online safety. We also noted that U.S. export controls affecting Anthropic’s Fable 5 and Mythos 5 were already sharpening the debate over security-driven restrictions and access to advanced AI capabilities, alongside expectations of voluntary commitments before binding rules emerge.
