U.S. Orders Anthropic to Disable Its Latest AI Model for Foreign Users Over Security Concerns

Anthropic CEO Dario Amodei / Credit: Wikimedia Commons Anthropic has abruptly suspended access to its newly released Claude Fable 5 artificial intelligence model after U.S. authorities raised national security concerns just days after its public launch. The company announced that it had been ordered to restrict foreign nationals from accessing Fable 5 and the related Mythos 5 model, forcing it to disable both systems for customers worldwide. “The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance,” Anthropic said in a statement. The dramatic move comes less than a week after Anthropic unveiled Fable 5, which the company itself had previously described as potentially “too powerful” for unrestricted release. The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

Jailbreaking refers to methods used to bypass security restrictions built into software systems. While Anthropic said authorities did not identify any specific security threats, the company acknowledged that Fable 5 had demonstrated capabilities beyond those of any model it had previously made publicly available. Before launch, Anthropic warned that the system could identify cyber vulnerabilities and exploit weaknesses in computer networks. As a result, the company limited early access to a small group of testers. The suspension marks the latest escalation in an increasingly bitter dispute between Anthropic and the Trump administration. Earlier this year, the Pentagon designated Anthropic a “supply chain risk,” effectively barring government agencies from relying on the company’s technology. Defense Secretary Pete Hegseth has previously described Amodei as a left-wing “ideological lunatic” who wants veto power over U.S. military operations. .@SenJackyRosen: “The decision to label Anthropic a national security risk was influenced by your personal and very public contract dispute.” Secretary Hegseth: “Anthropic is run by an ideological lunatic who shouldn’t have a sole decision-making over what we do.” pic.twitter.com/e9hx3fLo5w — CSPAN (@cspan) April 30, 2026 Anthropic responded by filing a lawsuit against the Department of War, arguing the designation was unjustified. As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models. Here’s what this means for you: Across Claude products, new sessions will run on your selected default model or Opus 4.8, and… https://t.co/YJTiDotS2v — ClaudeDevs (@ClaudeDevs) June 13, 2026 Claude Fable 5 was intended to compete directly with leading AI systems such as OpenAI’s ChatGPT and Google’s Gemini. Its sudden suspension has reignited fears that the most advanced AI models are being released faster than governments can assess their potential security risks. “We apologize for this disruption to our customers,” the company wrote on X. “We believe this is a misunderstanding and are working to restore access as soon as possible.” The post U.S. Orders Anthropic to Disable Its Latest AI Model for Foreign Users Over Security Concerns appeared first on The Gateway Pundit.
