Anthropic said Friday it has suspended access to two powerful AI models, Fable 5 and Mythos 5, to comply with a US national security order.<\/p>\n

Just three days after publicly launching Fable 5, the company said in a blog post that it received a government directive banning all foreign nationals, even those who work at Anthropic, from accessing Fable 5 and Mythos 5 over national security concerns.<\/p>\n

\u201cThe net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance,\u201d it said.<\/p>\n

The company said it received the letter at 5:21 pm (2121 GMT).<\/p>\n

Axios reported that the letter came from US Commerce Secretary Howard Lutnick.<\/p>\n

The US Commerce officials did not immediately respond to a request from AFP.<\/p>\n

The firm said that the letter did not state what specifically concerned the government. However, the firm\u2019s \u201cunderstanding is that the government believes it has become aware of a method of bypassing, or \u2018jailbreaking’\u201d the Fable 5 model such that it could aid hacking.<\/p>\n

Fable 5, released Tuesday, is a locked-down version of Mythos 5, a cutting-edge AI model that Anthropic has held back from the public amid concerns that it had unprecedented abilities to identify software vulnerabilities \u2014 or holes in code that hackers could exploit<\/p>\n

Mythos 5 \u2014 the unrestricted model \u2014 has only been released to select companies.<\/p>\n

Anthropic said it had reviewed the \u201cjailbreaking\u201d method at the center of the speculation and the hacking opportunities it exposed, but it does not believe Fable 5 gives hackers capabilities that are not already available through other public models.<\/p>\n

The firm said that none of its security testers had found a \u201cuniversal jailbreak,\u201d or a way to bypass its safeguards against helping hackers.<\/p>\n

\u201cWe disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people,\u201d the company said.<\/p>\n

\u201cIf this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers.\u201d<\/p>\n

Anthropic has been locked in a legal standoff with the Trump administration for refusing to allow its technology to potentially be used for mass surveillance and autonomous weapons, leading the Pentagon to cut contracts with the company.<\/p>\n

The war with Iran has been draining for all of us in Israel. But when I heard about a high casualty incident \u2013 ballistic missile impacts in Arad and Dimona that left nearly 200 people wounded \u2013 I drank a cup of coffee, packed a bag, and headed south.<\/p>\n

There, I spoke with Shilgit, the head of an after-school program for underprivileged youth. Standing outside her destroyed center, Shilgit said it was a miracle that no children were hurt and spoke about the community coming together in the hours since.<\/p>\n

As a Times of Israel reporter, I\u2019m committed to telling stories of resilience like Shilgit\u2019s. But my colleagues and I can’t do this alone.
