The most powerful AI model on earth was switched off worldwide by one government directive.
Not hacked. Not deprecated. Switched off.
This isn't an Anthropic problem. Every closed frontier API carries the same property: a single point of control, held by someone else. It's an architecture problem across the whole industry.
There are two ways out. Run open-weight models on infrastructure you control, no directive can revoke what you own. Or if closed models are part of your stack, build for portability so you can move providers without breaking things for your clients.
NuNet is built for both. That's been the case for 4 years. It just became a lot easier to explain.
How exposed is your current AI stack?
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.
