Trump Blocks Foreigners From Using Anthropic’s Latest AI Tech

The Trump administration ordered AI company Anthropic to suspend foreign nationals from using its most advanced AI models, Claude Fable 5 and Mythos 5, citing national security concerns. Anthropic complied by disabling access for all customers, following a previous ban on federal agencies using its products. The move highlights escalating tensions between the U.S. government and AI firms over ethical safeguards and national security.

To comply with the Friday directive, the company announced https://www.anthropic.com/news/fable-mythos-access that it disabled access to Fable 5 and Mythos 5, the latest models of Claude, for all customers. Anthropic stated that the government cited national security concerns but did not provide further details. The company says its newest technology has enhanced software engineering and visual understanding https://techcrunch.com/2026/06/09/anthropics-claude-fable-5-is-a-version-of-mythos-the-public-can-access-today/ compared to previous iterations. But Anthropic has also acknowledged potential concerns, releasing a preview model https://www.wired.com/story/anthropic-mythos-preview-project-glasswing/ in April to just a few industry partners to test for capabilities to use it to create hacking tools. Claude Fable 5 is the first publicly available version of the Mythos model, and the company said https://www.wired.com/story/anthropic-releases-claude-fable-5-mythos-5/ it has established “guardrails” such as blocking answers to questions on cybersecurity, biology, and chemistry. The Trump administration barred all federal agencies https://apnews.com/article/anthropic-pentagon-ai-hegseth-dario-amodei-b72d1894bc842d9acf026df3867bee8a from using Anthropic products in February. That same day, Trump called Anthropic “ a radical left, woke company https://truthsocial.com/@realDonaldTrump/posts/116144552969293195 ” amid his feud over it being unwilling to permit the military to use its technology. At the time, CEO Dario Amodei said that the US government’s demands—namely, mass surveillance of Americans and fully autonomous weapons—would allow it to violate the company’s safeguard policies https://www.bbc.com/news/articles/cvg3vlzzkqeo . As my colleagues Anna Merlan and Abby Vesoulis pointed out in March https://www.motherjones.com/politics/2026/03/artificial-intelligence-quitters/ , the US military previously used Anthropic’s Claude for “intelligence assessments, target identification and simulating battle scenarios” to prepare for its initial strikes on Iran. Anthropic has positioned itself as the ethical AI company https://futurism.com/artificial-intelligence/anthropic-scared-calls-global-freeze-ai , a significant contributor https://www.bloodinthemachine.com/p/how-anthropic-used-its-ai-ethicslop to its rapid ascent to the top of the industry especially as the public has increasingly disapproved of AI development https://www.motherjones.com/politics/2026/05/ai-data-center-gallup-opposition-american/ . The company filed for an initial public offering https://www.nytimes.com/2026/06/01/technology/anthropic-ipo.html earlier this month, and SpaceX’s success so far https://www.cnn.com/2026/06/12/business/live-news/spacex-goes-public-ipo since it entered the stock market on Friday—which made founder Elon Musk a trillionaire https://www.motherjones.com/politics/2026/06/elon-musk-trillionaire-spacex-ipo-oligarchy-democracy/ —could be an encouraging sign https://www.nytimes.com/2026/06/12/technology/spacex-ipo-openai-anthropic.html for it and its major competitor OpenAI https://www.reuters.com/technology/openai-files-us-ipo-after-anthropic-ai-giants-head-public-markets-2026-06-08/ . Meanwhile, other countries, like China and the United Arab Emirates, are pushing for “ sovereign AI https://www.forbes.com/councils/forbesbusinesscouncil/2026/03/09/how-countries-are-building-their-sovereign-ai-ecosystems-and-what-it-means-for-startups/ ,” or in other words, expanding their own AI infrastructure to overcome reliance on nations who have their own data privacy and safeguard rules. So despite the Trump administration’s attacks on Anthropic, developers are still raising funds https://www.theguardian.com/business/2026/jun/12/ai-ipos-stock-market and building at a frantic pace.
