Anthropic’s Fable 5 Cleared for Global Release as UK and France Ready Hormuz Naval Mission

The US has lifted export restrictions on Anthropic’s newest Claude models, allowing Fable 5 to roll out globally and restoring US access to the more powerful Mythos 5 after a three-week national-security review ^[1]. The Commerce Department had ordered Anthropic to cut off overseas access on June 12, fearing that China, Russia, or other adversaries could exploit the models to attack American infrastructure such as the electric grid or banking system ^[1].

Commerce Secretary Howard Lutnick told Anthropic in a letter seen by Reuters and The New York Times that the company would “no longer need a license for exports or in-country transfers” of Claude Mythos and Claude Fable, while reserving the right to reimpose curbs at any time ^[1]. Anthropic said it tightened safeguards after Amazon researchers found a jailbreak that could trick the model into producing exploit code, and that the bypass is now blocked in more than 99 percent of cases ^[1]. The stronger classifier comes with a trade-off: some benign coding and debugging prompts may now be rejected and routed to Opus 4.8 instead ^[1].

Anthropic is also deepening its public-private partnership. It launched a HackerOne program for security researchers to report jailbreaks, formed a 24/7 internal team to monitor emerging threats, and joined Amazon, Microsoft, and Google in drafting a framework to score the severity of AI jailbreaks ^[1].

Meanwhile, in world news, Britain and France announced late Friday that they are prepared to deploy a multinational military mission to secure navigation through the Strait of Hormuz ^[2]. British Prime Minister Keir Starmer and French President Emmanuel Macron called the waterway “a vital artery for the global economy” and said Oman has agreed to cooperate on safe passage through its territorial waters ^[2]. The declaration comes amid rising friction with Tehran, which has repeatedly rejected any foreign military presence in the strait and insists its security rests solely with littoral states ^[2].

Together, the two stories illustrate a weekend where frontier technology policy and Middle East power politics are moving in parallel: Washington is racing to deploy advanced AI while containing its risks, and European powers are positioning naval forces to protect a chokepoint that underpins global energy trade.
