White House Opposes Anthropic’s Expansion of Access to Mythos Model

According to The Wall Street Journal, the White House has signaled its opposition to Anthropic’s plan to expand the usage scope of its AI model, Mythos. Anthropic recently proposed granting access to Mythos for approximately 70 additional companies and institutions, which would bring the total number of authorized entities to around 120. In response, government officials explicitly objected on security grounds. Sources familiar with the matter said some White House officials are concerned that Mythos possesses the capability to launch cyberattacks and cause large-scale disruption online, viewing the expansion of access as a security risk. Additionally, some officials have questioned Anthropic’s computational resources, expressing doubts about whether the company can simultaneously support a significantly increased number of users while ensuring effective government access to and use of the system. Currently, although both sides aim to ease tensions, the disagreement over Mythos access remains unresolved.
