Anthropic’s access to its Mythos 5 model widened after the company resolved Trump administration concerns tied to national security. The Commerce Department’s Howard Lutnick wrote to Anthropic that the model can be released to a “certain trusted partners” set after the lab addressed “risks associated with the Covered Models.” The clearance follows a two-week confrontation in which the U.S. abruptly barred Anthropic from giving foreign nationals access to Mythos 5 and Fable 5, prompting Anthropic to disable global access and enter talks with government officials. Anthropic said the restart applies to Mythos 5 for a small group of cyber defenders and infrastructure providers, while discussions about restoring Fable 5 access continue. For higher education and research organizations evaluating AI tools, the episode highlights how AI access, export controls, and cybersecurity guardrails can change quickly—affecting vendor selection, data-sharing permissions, and compliance documentation.
