Anthropic has received approval from the United States government to restore access to its Claude Mythos 5 AI model for selected American organizations responsible for operating and defending critical infrastructure.
The decision partially reinstates access to Anthropic’s most advanced cybersecurity-focused model after restrictions were introduced on June 12.
According to the company, it has been working closely with the US government since the restrictions were imposed to restore access to both Claude Mythos 5 and Claude Fable 5.
Under the latest approval, Claude Mythos 5 can now be redeployed to a limited group of US organizations involved in critical infrastructure protection and cybersecurity operations.
Anthropic said it is moving quickly to restore access for the approved organizations and will continue supporting them with the cybersecurity capabilities of the model.
Despite the development, the company clarified that Claude Mythos 5 is not yet available for general use. Anthropic said discussions with the government are ongoing to expand access to a broader range of eligible organizations.
Claude Fable 5 also remains unavailable to the general public. The company stated that it continues to engage with US authorities in an effort to secure approval for wider deployment of the model.
The phased restoration reflects the continued oversight of advanced AI systems used in sensitive cybersecurity environments while balancing national security considerations with technological innovation.
