US Government Suspends Access to Anthropic's Fable 5 and Mythos 5 Due to National Security Concerns

The US government has issued an export control directive to suspend all access to Anthropic's Fable 5 and Mythos 5 models for foreign nationals, citing national security authorities. This directive requires Anthropic to disable these models for all customers to ensure compliance, although access to other models will remain unaffected. The government has not provided specific details regarding its concerns, but it is believed that a method to bypass Fable 5, referred to as a 'jailbreak', has been identified. Anthropic has contested the necessity of this action, arguing that the vulnerabilities are minor and similar issues can be found in other publicly available models. The company is working to restore access and has announced partnerships with Tata Consultancy Services and DXC Technology to deploy their Claude model in various industries.
