An AI jailbreak is when a hacker exploits vulnerabilities in an AI model, bypassing its ethical guidelines in an attempt to carry out restricted actions.<\/p>\n<p>The company sought to play down the issue, saying that the vulnerabilities appeared to be &#8220;relatively simple&#8221; and that it had found publicly available models were able to identify them.<\/p>\n<p>It added that while it was complying with the directive, it disagreed that a &#8220;narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people&#8221;.<\/p>\n<p>Anthropic also stressed that it had developed &#8220;strong safeguards that greatly reduce the likelihood that Fable is misused for tasks related to cybersecurity&#8221;.<\/p>\n<p>Responding to the news on X, Jordan Bardella, a Member of the European Parliament and president of France&#8217;s far-right National Rally party, said the move was a sharp reminder that artificial intelligence is a &#8220;major issue of national sovereignty&#8221;.<\/p>\n<p>&#8220;Nations that do not quickly develop their own model(s) will always depend more and more on the choices of other powers: France must accelerate its support for the gem Mistral AI and the entire AI ecosystem,&#8221; he added.<\/p>\n<p>Tom Tugendhat, a British MP and former security minister, said it showed how technology has become increasingly central to sovereignty.<\/p>\n<p>&#8220;Disabling Fable 5 and other models for foreigners is not a misunderstanding or a mistake, it\u2019s the inevitable result of technology shaping warfare so that sovereignty is more about code than cannons,&#8221; he wrote on social media.<\/p>\n<p>It is not the first time Anthropic and the Trump administration have clashed.<\/p>\n<p>In February, Trump directed US federal agencies to immediately stop using Anthropic&#8217;s technology after CEO Dario Amodei and his firm objected to its technology being used for certain defence purposes.<\/p>\n<p>&#8220;We don\u2019t need it, we don\u2019t want it, and will not do business with them again!,&#8221; Trump wrote on Truth Social at the time, saying there would be a &#8220;phase out period&#8221; of six months.<\/p>\n<p>Anthropic later announced it would be taking legal action against the government after it also designated the company a &#8220;supply chain risk&#8221;.<\/p>\n","protected":false},"excerpt":{"rendered":"Published on 13\/06\/2026 &#8211; 11:45 GMT+2\u2022Updated 16:31 Anthropic has responded after the Trump administration issued a directive banning&hellip;\n","protected":false},"author":2,"featured_media":736177,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[276,45,49,48,61,183],"class_list":["post-736176","post","type-post","status-publish","format-standard","has-post-thumbnail","category-business","tag-artificial-intelligence","tag-business","tag-ca","tag-canada","tag-technology","tag-usa"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/736176","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=736176"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/736176\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/736177"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=736176"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=736176"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=736176"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
