On a Friday afternoon at 5:21 PM, Anthropic received a US government export control directive ordering the company to suspend access to its latest AI model, Claude Mythos 5, according to The Verge. The move came while Americans were celebrating the country's first World Cup win and a New York Knicks championship.
According to the Washington Post, Trump administration officials had been weighing export controls on Anthropic for weeks before acting, after a dispute over Mythos access for a China-linked firm. The Washington Post also reports that the episode reflects a broader breakdown in trust between Anthropic and the White House.
Anthropoc's senior leaders met with top Trump administration officials on June 15 in an attempt to broker a resolution, but no deal was reached, according to The Information (via Techmeme). An Anthropic spokesperson said both sides "are working quickly to get this resolved," according to MoneyControl.
Cybersecurity experts are skeptical of the administration's stated concerns. According to CyberScoop, security professionals do not believe the model—also referred to as Fable 5 in some coverage—presents a unique threat compared to other AI systems already available.
The dispute has created friction across the industry. According to Yahoo Tech, an OpenAI employee withdrew support from an amicus filing after Anthropic's policy shift during the standoff. The Atlantic described the situation as the White House "ratcheting up its war" against the company, while The Daily Upside framed it as Anthropic fighting "to bring its most powerful AI models back online."
If the US government can compel an American AI lab to take its flagship product offline over export concerns, it marks a significant new precedent for federal intervention in who gets access to frontier AI—and on what terms.
