The US government just forced Anthropic to take its most advanced AI models offline

The US government just forced Anthropic to take its most advanced AI models offline, and I filmed this from a plane because it's that unprecedented.

The order moved to block foreign access to Fable 5 and Mythos 5, and it's broad enough, covering foreign nationals even inside the US, that the practical way to comply was to pull the models for everyone. This is the first time I can point to a frontier model getting rolled back like this. I walk through the three layers I see: the safety concern around a reported jailbreak pathway, the "foreign national" language that works less like a surgical restriction and more like an off switch, and the business reality that makes me think this gets resolved fast. I still think Fable is probably the best model in the world right now, and a full review is coming. But the bigger shift is that frontier model access is becoming a policy surface, and raw model quality is no longer the only thing that matters.

What's really happening with frontier AI model access?
The common story is this was routine export control, but the reality is much stranger and much bigger.

In this video, I share the inside scoop on what the Fable 5 shutdown really means:
• Why a single jailbreak claim froze a frontier model
• How a "foreign national" rule shut off everyone
• What model dependency now means for your workflow
• Where AI governance and access quality go next

For operators, the opportunity is still real, but the smart move now is to keep your alternatives warm and never build critical work on one model staying available on yesterday's terms.

 
Love to see the state of exception being used for yet another flagrant, incompetent, insider trading scheme. Sucks because Fable 5 was a noticeable improvement - I built out a hybrid place-and-router with analytical PEX for my PCB designs in like 3 days.

As much as many actions are lately -- I don't think this is an insider trading based decision. Two reasons: 1. This limits the market for Anthropics leading edge product, and 2. Cybersecurity at DISA/USA/whatever org it is these days has been increasingly aggressive over the years on limiting access to certain technologies to non-US citizens, and regulating what can come into the USA from "outsiders".

Expanding a little on #2 -- When IBM sold it's servers to Lenovo, the US govt issued directives that effectively stopped government contractors from being able to buy "IBM" servers because of their source of origin -- this was back in like 2011. Since then they've continued to clamp down -- initially with "soft" restrictions like TSA compliance for computers for government contractors, and lately to items applying across the entire market -- GPU export, Router import, etc. This is a (possibly overzealous) cybersecurity posture action IMO. US Cyber keeps adding on and seeing what they can get away with..

If only they hadn't been building backdoors into everything they can for the last 25 years...

Oh agreed. At this point, I just try to limit my software and systems to USA backdoors only. Better to only be backdoored by one country than several -- at least out of the box.

A little more on why this probably happened, a post from 4 days ago (Anthropic advertised best in the world cybersecurity capabilities):


For a small group of cyberdefenders and infrastructure providers, we’re also launching Claude Mythos 5. It’s the same underlying model as Fable 5, but with the safeguards lifted in some areas.2 Mythos 5 will initially be deployed through Project Glasswing, in collaboration with the US government, as an upgrade to Claude Mythos Preview. It has the strongest cybersecurity capabilities of any model in the world. Soon, we intend to expand access to Mythos 5 through a broader trusted access program.
