Anthropic restricts access to advanced AI models following US government directive

The artificial intelligence company Anthropic has suspended access to its Fable 5 and Mythos 5 models following a directive from the U.S. Department of Commerce. U.S. Secretary of Commerce Howard Lutnick reportedly issued the order, citing national security concerns. The directive prohibits foreign nationals, including Anthropic's own employees, from accessing these specific AI models. This measure was implemented just three days after the public release of Fable 5. While the government has not specified the exact nature of the risks, reports suggest authorities fear a potential jailbreak vulnerability in Fable 5 that could facilitate cyberattacks. Anthropic has contested the necessity of the order, stating that no universal security bypass has been identified and that the model's capabilities are comparable to existing public tools. The company has fully complied by disabling the systems for all users.
