US orders Anthropic to ban AI models for all foreign nationals | Technology News

The company said it received an export ban to stop access to Fable 5 and Mythos 5 to foreign nationals.

An AI company Anthropic has banned the use of its newly released software, in compliance with United States government law.

In blogs published on Friday, the company behind the Claude chatbot said that government agencies have ordered to prevent all foreign nationals from accessing the AI ​​versions Fable 5 and Mythos 5, citing national security.

Anthropic said it received the order at 5:21pm (21:21 GMT) on Friday and the letter did not detail the government’s security measures.

The ban also applies to visitors to the US – including those who work for Anthropic.

Because of the system, the company had to block access for everyone soon, it said.

The artificial intelligence behind Anthropic’s Mythos AI brand is very good at detecting software problems, some of which have gone unnoticed for years.

This capability has been used by US officials and selected companies to close security gaps.

However, the concern from the beginning was that such AI could become a dangerous cyberweapon in the wrong hands.

The Fable 5 version, released this week, is based on Mythos technology, but its cybersecurity and biotechnology capabilities are limited.

Mythos 5 is the full non-public version, which should continue to be used by government agencies and selected companies to standardize their systems.

Anthropic insisted that at this point it has only received limited information from the government.

The company said it had reviewed a report that, in its analysis, may have triggered the plan.

Anthropic experts concluded that this refers to the limited ability to use AI to review software code and correct errors.

Models from other providers, such as GPT-5.5 from OpenAI, also have this capability, the company confirmed.

Anthropic said that they do not agree that applications used by hundreds of millions of users should be closed for these reasons, and that the security measures in Fable 5 have been tested extensively.

Earlier this month, Anthropic announced that the world’s leading artificial intelligence companies should join forces to stop advanced AI systems, warning that the technology is advancing so fast that there is a risk that humans will fail.

The company said in a blog post in early June that, as advanced AI becomes more operational, “it may be good for the world to have the option to slow down or temporarily stop” its development.
