US Directive Forces Anthropic to Disable Fable 5 Worldwide
All the news about Anthropic’s new AI fight with the White House
Anthropic was already navigating one dispute with the government in its standoff with the Pentagon, and then came an order on June 12th to block off foreign access to its most recently released AI models, Fable 5 and Mythos 5. When they launched on June 9th, Anthropic said “Fable 5’s capabilities exceed those of any model we’ve ever made generally available,” and that Claude Mythos 5 had the same underlying model, “but with the safeguards lifted in some areas.”
According to reports, the order came after conversations between Amazon and the White House about researchers saying they found ways to get Fable 5 to serve information that could be used in cyberattacks.
Anthropic responded by shutting access to both models for all customers, saying, “We are complying with the government’s legal directive and are removing access to Fable 5 and Mythos 5 for all users. However, we disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people.”

Trump’s Anthropic shutdown just made the case for non-American AI
At Washington's request, Anthropic suddenly took its newest and most powerful AI models offline over the weekend. The American company said it had little choice after the White House demanded it block access for all foreign nationals, including its own employees. Abroad, the incident offered a sobering reminder that the US not only dominates frontier AI - its government also wields power over who gets to use it.
The Trump administration's action was swift, sweeping, and imposed with little warning or explanation. The unprecedented shutdown of the Fable 5 and Mythos 5 models - which were already subject to safeguards limiting their use in " …

Apenas dias após o lançamento, o governo norte-americano emitiu uma diretiva de controlo de exportações que obrigou a Anthropic a desligar globalmente os seus dois modelos mais avançados. A Comissão Europeia reagiu com preocupação e invocou soberania tecnológica.

China may have accessed Mythos
According to a new report from Semafor, the White House's decision to impose export restrictions on Anthropic's Mythos was driven in part by fears that it had been accessed by a group linked to China. If the Chinese government actually had access to Mythos 5 or Fable 5, it would present a serious national security risk. The government could also attempt to reverse engineer the model through distillation, a method in which a "student" AI is trained on a more advanced model to replicate its behavior.
The White House has not confirmed this report, and a post on X by Trump adviser David Sacks did not mention China. Instead, Sacks focused on a r …

Amazon security research reportedly led to the White House’s Anthropic Fable ban
According to the The Wall Street Journal, the export control directive that led to Anthropic cutting off access to Fable 5 and Mythos 5 was triggered in part by cybersecurity research from Amazon and conversations between CEO Andy Jassy and the White House. According to the report, the paper from Amazon claims that, through a series of prompts, it was able to get Fable 5 to serve up information that could be used in cyberattacks. Amazon has yet to respond to a request for comment.
Shortly after Jassy shared the company's findings with the government, it made the call to block its use by foreign nationals. Complicating this issue is that man …

Anthropic cuts off Fable 5 and Mythos 5 access following government order
On Friday evening, the government ordered Anthropic to block access to Fable 5 and Mythos 5 for all foreign nations, both inside and outside the US, due to national security concerns. That order included employees of Anthropic. To meet those demands, the company has completely cut off access to the models for all customers.
In a statement, Anthropic said that while it was complying with the order, the government "did not provide specific details of its national security concern." Instead, it claims that any evidence of potential jailbreak was provided verbally, and that the vulnerabilities discovered were minor and available via other model …

Anthropic apologizes for invisible Claude Fable guardrails
Anthropic has apologized for stealthily throttling its new AI model, Claude Fable 5, with hidden guardrails that undermine both researchers and rivals using it to develop competing systems. The company says it is reversing course and will be more transparent about when the restrictions kick in, even if that means Fable refuses more queries.
Fable is the first widely available model in Anthropic's Mythos class of AI systems, a group the company has spent months warning are too dangerous for public release. Anthropic says it has addressed some of those risks by launching Fable with safeguards that prevent it from responding to certain "high-r …
