Last week, the U.S. \u200bgovernment allowed the company to release Mythos 5 but only to some &#8220;trusted&#8221; U.S. organizations.<\/div><div>&#8220;We&#8217;ve received notice that the Department of Commerce has lifted export controls \u200bon Claude Fable 5 and Mythos 5. We&#8217;ll begin restoring access tomorrow,&#8221; Anthropic said in an X post.<\/div><div>A letter to Anthropic \u2060from U.S. Commerce Secretary Howard Lutnick that was seen by Reuters also said the export controls were withdrawn.<\/div><div>Anthropic had &#8220;agreed to proactively detect and address security risks associated \u200bwith the models,&#8221; Lutnick said. It had also agreed to work diligently with the U.S. government on protocols for Mythos, Fable and future models and to inform the \u200bU.S. government of any malicious activity, he added.<\/div><h2>US GOVERNMENT MIGHT REEVALUATE IF CIRCUMSTANCES CHANGE<\/h2><div>Lutnick, however, said that the department &#8220;reserves the right to reevaluate the decisions made in this letter and the necessity of reimposing a license requirement, should circumstances change or should Anthropic fail to adhere to its commitments&#8221;.<\/div><div>Both Fable and Mythos use the same underlying AI model, but Fable is designed to \u200bbe widely available for public use whereas some safeguards are lifted for Mythos.<\/div><div>Anthropic has implemented a new safeguard that targets and blocks a technique that it believes \u200bthe government viewed as a method of bypassing or &#8220;jailbreaking&#8221; Fable 5, a company source said, declining to be identified.<\/div><div>The source, however, added that the vulnerabilities found by the technique which \u200chad concerned the \u2060government had been known and patched earlier.<\/div><div>Experts have said that Mythos models, in the wrong hands, could dramatically accelerate sophisticated cyberattacks, particularly in sectors such as banking that rely on complex, interconnected, and often decades-old technology systems.<\/div><div>The government&#8217;s decision on Friday to allow access to Mythos to some &#8220;trusted&#8221; U.S. organisations came in tandem with an announcement by rival OpenAI that it had delayed a full public launch of GPT-5.6 at the U.S. government&#8217;s request, limiting its access to a small group of vetted partners.<\/div><div>Those \u200bgovernment actions had drawn much criticism that \u200bthe administration&#8217;s choosing of which companies \u2060were worthy of being considered &#8220;trusted&#8221; was unfair and not transparent.<\/div><div>Increased scrutiny of AI models this month began with U.S. President Donald Trump&#8217;s signing of an executive order establishing a voluntary framework for AI developers to offer &#8220;covered frontier models&#8221; to the U.S. government \u200bfor up to 30 days before releasing them to trusted partners.<\/div><div>Isaac Harris, executive director of the Frontier Security Institute, a \u200bnonprofit focused on AI \u2060and national security, said that Tuesday&#8217;s lifting of curbs indicated that &#8220;there\u2019s now a process for standards of the U.S. models.&#8221;<\/div><div>But he added: &#8220;There&#8217;s still a question mark as to how equivalently dangerous capabilities coming from China with less guardrails will be handled by the administration in the U.S. market.&#8221;<\/div><div>Both OpenAI and Anthropic have confidentially filed for U.S. initial public offerings.<\/div><div>Anthropic&#8217;s \u2060relationship with \u200bthe U.S. government has been particularly rocky this year. The Pentagon designated the company a &#8220;supply-chain risk&#8221;, preventing \u200bcontractors from using Anthropic&#8217;s AI when working for the U.S. military, after the company refused to allow its models to be used for mass domestic surveillance or fully autonomous weapons systems.<\/div><div><address><div><div><noscript>\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"120\" height=\"120\" alt=\"Chris Thomas\" class=\"wp-image-1817\" src=\"https:\/\/reliablemovingcrews.com\/wp-content\/uploads\/2026\/06\/747ebc283388fd75d7e7df92e20a6586.avif\"\/><\/figure>\n<\/noscript><\/div><div>Chris Thomas<\/div><\/div><div><ul><li><span><div><svg><title>Email<\/title><\/svg><\/div><\/span><\/li><li><span><div><svg><title>X<\/title><\/svg><\/div><\/span><\/li><li><span><div><svg><title>Linkedin<\/title><\/svg><\/div><\/span><\/li><\/ul><\/div><\/address><\/div><\/div><p>Read more <a href=\"https:\/\/reliablemovingcrews.com\/?p=3392\">FBI determines Nancy Guthrie kidnapping notes to be fakes, source says<\/a><\/p><p>Read more <a href=\"https:\/\/reliablemovingcrews.com\/?p=3390\">Gold set for worst quarterly loss in 13 years on hawkish Fed stance<\/a><\/p><p>Read more <a href=\"https:\/\/reliablemovingcrews.com\/?p=3388\">Foreign investors buy record amounts of Canadian government debt, lowering Carney\u2019s\u00a0borrowing costs<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Anthropic said on \u200bTuesday that the U.S. Commerce Department lifted export controls on its Fable and Mythos AI models, less than three weeks after the \u200ccompany was ordered to suspend access to its most advanced AI models over national security risks.<\/p>\n","protected":false},"author":1,"featured_media":3393,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[84],"class_list":["post-3394","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","tag-business"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 -
