At 5:21pm ET on Friday, the Commerce Department disabled the most capable commercial AI model in the United States. A letter to Anthropic ordered access cut for any foreign national anywhere in the world, including the company’s own non-citizen employees. Anthropic, unable to operationally wall its own staff off, had to shut Fable 5 and Mythos 5 down for every customer to comply.

The stated trigger: another company told Commerce it had jailbroken Mythos. The directive cited national security authority. The letter, per Anthropic’s own statement, “did not provide specific details” of the concern.

The unnamed competitor is where this turns. OpenAI sells GPT-5.5-Cyber into federal agencies, state and local government, and allied governments via its Trusted Access program. Axios reported last month that GPT-5.5 is nearly as good as Mythos at offensive cyber work. Fable 5 going dark removes the only commercial competitor in those procurement conversations. The jailbreak Anthropic describes is asking the model to read a specific codebase and identify software vulnerabilities. That is the exact use case OpenAI sells to federal cyber defenders. Whoever surfaced this to Commerce knew which capability to flag.

The detail being underplayed across the reporting: the directive applies to foreign nationals anywhere, including foreign-national Anthropic employees inside the United States. That isn’t export control. It’s a workforce restriction on a private US company, executed by letter, with no public reasoning.

The precedent now established: a competitor with administration access can disable a US lab’s flagship product via BIS national security authority on an unverified jailbreak claim, no specifics required, no review window, no obligation to justify. The lever exists, and Anthropic is the demonstration. Every frontier lab is repricing political alignment as we speak.

For non-US customers and partners, the implication is clean: your access to frontier US AI is a discretionary US decision, executable in an afternoon, with no notice. The UK AISI helped red-team Fable 5. It cannot now use the model it tested.

What to watch over the next week: whether Anthropic gets carve-outs for internal employee access, whether any congressional voice pushes back publicly, and whether OpenAI or xAI speak. Silence from those two is itself a tell.

Amanda Askell isn't a US citizen. Anthropic chief philosopher can't talk to Mythos until this is sorted.

I’m sick of hearing these women say Erika has “been though a lot”. She’s got a roof over her head, a makeup/hair team, still has jewelry, designer clothes, travels. She just doesn’t have the highest level. You know who’s been thru a lot? The victims. #RHOBH

We need more black housewives to be vocal in their support of Garcelle. The reason they feel this way about what Erika did to Garcelle’s 14 year old son does pair with the fact that white America doesn’t see black children as children. #RHOBH #rhobhracists

@BrettTyre As one of those 6 people, it is deeply unfair. 😅

Today, many children in BC returned to school during an ongoing pandemic, but without the protection of mask mandates. On Mar.16 I wrote to the Public Health Officer re the inequitable impact on immunocompromised people of ending the mask mandate, urging her to maintain it 1/2

Saying “what I did was wrong and I am sorry for losing my temper” would have made such a difference.

Authorities in Mariupol say the bomb shelter at the theatre held up to the bomb blast.

They’re now working on getting people out.

[Christo Grozev @christogrozev]

The last hospital in Mariupol, by @AP. All others were bombed out by Russia. People doctors can't save are lined up in the basement, including infants. It's the most heart wrenching footage of this war.

[Illia Ponomarenko 🇺🇦 @IAPonomarenko]

You know, guys, I spent 5 years as a student in Mariupol.
Those were happy years. Lots of love and inspiration.
Russia is literally destroying everything I love.
It has already ruined my hometown, my university, my new apartment in Bucha.
Kyiv is the final frontier.

[George Takei @GeorgeTakei]

When Russia sanctioned Canada, it barred leaders from all major federal parties, including conservative leaders.

But when Russia sanctioned the U.S., it barred Democratic leaders only. It didn’t name a single GOP leader.

The signal couldn’t be clearer.

[maksym eristavi. @maksymeristavi]

when foreigners casually drop ‘bombing of kyiv’ these pics always come to mind. this is what #RussianColonialism did to chechnya and grozny when they tried to leave the empire in 2000. a war crime of horrific scale, but the rest of the world was like ‘meh’, so moscow continued
