On June 12 the U.S. government ordered Anthropic to suspend access to Mythos and Fable 5 for foreign nationals, and Anthropic disabled the models for all users. The action was taken after government officials raised national security concerns.","On June 26 the Commerce Department allowed Anthropic to give Mythos back to some trusted U.S. partners. This limited release has been approved while officials continue security evaluations, and the company has said it will follow any licensing rules. Although the directive first restricted access, the new letter opened a narrow path for some U.S. firms to use Mythos.","Observers say the move reduced tensions between the company and the administration, and many technology firms are watching closely. Since tests and reviews found potential security issues, companies and the government are now in dialogue to manage risks and benefits. However, the full contents of the Commerce letter have not been made public. Experts expect further guidance and possible licenses in coming weeks. Companies will monitor how rules are applied."],"wordCount":182,"readTime":2},"vocabulary":[{"word":"Commerce Department","example":"The Commerce Department sent the letter on June 26.","phonetic":"/ˈkɒm.ɜːrs dɪˈpɑːrtmənt/","definition":"The U.S. government department involved in trade and export controls."},{"word":"trusted partner","example":"Mythos was returned to some trusted partners.","phonetic":"/ˈtrʌstɪd ˈpɑːrtnər/","definition":"A company or group chosen to receive access because it is considered reliable."},{"word":"license","example":"The limited release is subject to licensing.","phonetic":"/ˈlaɪsəns/","definition":"Official permission to do or use something."},{"word":"evaluate","example":"Officials will evaluate security risks.","phonetic":"/ɪˈvæljueɪt/","definition":"To examine something and judge its value or safety."}],"quiz":[{"answer":"Anthropic","question":"Who builds Mythos?"},{"answer":"June 26","question":"When did the Commerce Department allow Anthropic to give Mythos back to some trusted U.S. partners?"},{"answer":"Commerce Department","question":"Which department allowed the limited release?"}],"discussion":[{"question":"Do you think limited access to powerful technology is understandable?
