The AI firm Anthropic has blocked access to its newly released cutting-edge software, following an order by the United States government.
In a blog post published Friday, the company behind the Claude chatbot said government agencies had instructed it to prevent all foreign nationals from accessing the AI models Fable 5 and Mythos 5, citing national security concerns.
Anthropic said it received the order at 5:21pm (21:21 GMT) on Friday and that the letter did not explain the governmentโs specific security concern in detail.
The ban also affects foreigners currently in the US โ including those working at Anthropic.
As a result of the order, the company had to cut off access for everyone at short notice, it said.
The artificial intelligence behind Anthropicโs Mythos AI model is particularly adept at detecting software vulnerabilities, some of which have remained undiscovered for decades.
This capability has been used by US authorities and selected companies to plug security gaps.
However, a concern from the outset has been that such AI could become a dangerous cyberweapon in the wrong hands.
