White House Blocks Anthropic's 'Mythos' AI Expansion on Security Grounds

The White House has intervened to halt plans by AI startup Anthropic to broaden access to its latest model, codenamed 'Mythos,' citing national security concerns. The decision underscores escalating federal scrutiny of generative AI, with officials warning that wider availability could enable foreign adversaries to launch sophisticated cyberattacks or compromise sensitive systems. Despite Anthropic's reputation as a safety-focused developer, the administration is prioritizing risk mitigation over rapid deployment, signaling a tougher regulatory posture for cutting-edge AI models. The move aligns with ongoing policy efforts to address the dual-use potential of large language models that could threaten public safety.
