The U.S. government has eased restrictions on Anthropic's advanced Claude Mythos 5 artificial intelligence model, allowing the company to make it available to more than 100 trusted organizations, including major corporations and government agencies.
The decision marks a partial relaxation of controls introduced earlier this month over concerns about the capabilities of frontier AI systems.
In a letter to Anthropic executive Tom Brown, Lutnick said the administration had determined that appropriate security measures were in place for approved institutional users.
The authorization applies only to the cybersecurity-focused Mythos 5 model. The government has not announced a decision regarding Anthropic's consumer-oriented Claude Fable 5, leaving its broader public release uncertain.
Industry observers say frontier AI developers are facing closer scrutiny as policymakers seek to balance innovation with national security and cybersecurity concerns through expanded regulatory oversight.
