The US government has partially lifted restrictions on Anthropic’s Claude Mythos 5 AI model, allowing the company to grant access to more than 100 US organizations, including large corporations and government agencies, according to wired.com and techcrunch.com.
In a letter to Anthropic cofounder and chief compute officer Tom Brown obtained by wired.com, US Commerce Secretary Howard Lutnick stated he had “determined that appropriate safeguards are in place.” Lutnick wrote that “Anthropic has worked with the U.S. government to address risks associated with the Covered Models. These efforts have yielded significant progress.”
According to wired.com, the government imposed the restrictions on June 12, triggering a two-week period during which Anthropic pulled both Mythos 5 and its consumer-facing version, Claude Fable 5, from the market. Techcrunch.com noted that the new allowance includes access for non-American employees at approved organizations.
However, according to wired.com, the government has not yet permitted a broader rollout of Mythos 5, and “said nothing about the fate of Claude Fable 5.” Anthropic spokesperson Eduardo Maia Silva told wired.com the company “received notice from the US government that Mythos 5, our strongest cybersecurity model, can be redeployed to a small group of cyber defenders and infrastructure providers.”
According to wired.com, Anthropic is still in discussions with the White House about restoring access to Fable 5, with talks expected to continue over the weekend.
