Washington, United States – The U.S. government has partially lifted its recent ban on Anthropic's advanced Claude Mythos 5 artificial intelligence model, authorizing its use by more than 100 "trusted" U.S. organizations. In a letter dated Friday, June 26, 2026, Commerce Secretary Howard Lutnick informed Anthropic’s chief compute officer, Tom Brown, that selected companies and institutions may again access the model after a two-week suspension triggered by an export control directive. The restored access covers a roster of approved users that includes several Fortune 500 corporations as well as organizations that operate and defend critical infrastructure across the United States. The letter, sent on behalf of the Department of Commerce, states that Lutnick has determined that "appropriate safeguards are in place" to permit these trusted partners to use Claude Mythos 5. He cited "significant progress" in establishing security protocols to govern how the powerful system is deployed, following what sources described as intense, daily negotiations between Anthropic executives and federal officials. The decision represents a partial reversal of the earlier directive, maintaining export controls while allowing a controlled domestic rollout under tightened oversight and monitoring requirements for the approved entities.
