U.S. government gives Anthropic green light for limited re-release of Mythos 5

Key Points:

• The U.S. government has allowed Anthropic to redeploy its Mythos 5 AI model to about 100 trusted organizations, including government agencies and private companies, primarily for defensive cybersecurity purposes.
• Commerce Secretary Howard Lutnick cited confidence in Anthropic’s guardrails as the reason for restoring limited access to Mythos 5, after previously ordering the shutdown of Mythos 5 and Fable 5 due to national security concerns.
• Anthropic continues discussions with the government to restore access to Fable 5, its most powerful consumer model, while OpenAI announced a phased release of its latest GPT-5.6 models in response to federal requests.
• Export control regulations forced Anthropic to take its advanced models offline entirely because foreign nationals working at Anthropic and partner organizations could access them, raising national security risks.
• The situation highlights ongoing tensions between AI innovation and government oversight, with companies like OpenAI advocating for a more streamlined safety vetting framework to avoid limiting access to advanced AI tools.
