White House Opposes Anthropic Plan for Mythos Access, WSJ Says

The White House objected to expanding access over security and computing-power concerns as Mythos remains limited to about 50 organizations, officials said.

  • On Wednesday, The White House opposed Anthropic's plans to expand access to its Mythos AI model to 120 companies, citing security concerns and computing power constraints, according to the Wall Street Journal.
  • Anthropic had proposed expanding access from approximately 50 to 120 organizations under Project Glasswing, but a recent security breach involving unauthorized users intensified government anxiety about further expansion.
  • Mythos can autonomously execute 32-step corporate network attacks and succeeded on 73% of expert-level cybersecurity tasks, leading authorities to fear broadening access competes with The National Security Agency's own use.
  • The White House is simultaneously developing executive action to onboard Anthropic's models despite The Pentagon previously designating the firm a national security supply chain risk.
  • This dispute highlights a novel regulatory challenge in governing offensive AI models, as the administration claims it is "balancing innovation and security while cooperating with the private sector.
