White House pushes back on wider rollout of Anthropic’s Mythos AI over security fears

The White House has pushed back against Anthropic's plan to expand access to its Mythos AI model, complicating plans to put the technology in the hands of more companies and organisations. Mythos can identify and exploit software vulnerabilities at scale, and US officials are concerned that a wider rollout could heighten security risks. Anthropic had proposed increasing access from around 50 organisations to 120, including companies tied to critical infrastructure. The model's capabilities have already unsettled agencies, and officials fear its power could be misused if it spreads too quickly. The White House remains closely involved in Mythos's rollout, underscoring its national security implications. Anthropic has emphasised caution, with no immediate plans for a public release and a focus on controlled access through select partnerships.
