How did Anthropic respond to the government's directive?

Nathaniel Whittemore 0:51
Hello, friends. Welcome back to the AI Daily Brief. For the first time in the three-year history of this show, news has broken on a Friday afternoon that is too significant to wait until Monday to explore. Last night, just before 9 Eastern Time in the U.S., Anthropic tweeted, the U.S. 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 cloud models is not affected.
Nathaniel Whittemore 1:31
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

What are the implications of the US government's actions on AI models?

Nathaniel Whittemore 1:38
After this absolutely stunning news, journalists and internet sleuths flew into a tizzy to try to figure out what the heck had actually just happened. The Wall Street Journal added some color, reporting that Commerce Secretary Howard Lutnick had sent a letter to Anthropic CEO Dario Amadei announcing that the new models Fable 5 and Mythos 5 were now subject to export restrictions. meaning usage by customers outside the U.S. as well as foreign nationals within the U.S. would be prohibited. So where did this seemingly capricious policy come from? It was apparently a report from another company about a jailbreak it had discovered. Anthropic gave more details in their blog post, writing, We received the directive from the government today at 5.21 p.m.
Nathaniel Whittemore 2:16
The letter did not provide specific details of its national security concern. Our understanding is that the government believes that it has become aware of a method of bypassing or jailbreaking Fable 5.

What concerns have been raised by experts about the government's decision?

Nathaniel Whittemore 2:27
We reviewed a demonstration of this specific technique being used to identify a small number of previously known minor vulnerabilities. These vulnerabilities all appear relatively simple, and we have found that other publicly available methods are able to discover them as well without requiring a bypass. And basically from there went on to say that they just don't buy the US's logic. They point out that in the weeks leading up to the release of Fable, they worked with the US government and many others to red team Fable safeguards for a significant amount of time. They pointed out that, quote, no testers have yet been able to find a universal jailbreak, a jailbreak method that can very broadly bypass the model safeguards.
Nathaniel Whittemore 3:00
Indeed, they write, we suspect that perfect jailbreak resistance is not currently possible for any model provider. Every safeguard used in the industry is vulnerable to non-universal jailbreaks, which can elicit some cyber information in specific circumstances, and it is likely that universal jailbreaks will eventually be found in the future. They said, Given that perfect jailbreak resistance does not appear to be possible today, Anthropic adopted a defense-in-depth strategy with Fable 5. We aimed to make jailbreaks either narrow or very expensive to produce, and to combine this with thorough monitoring to quickly detect and shut down any successful attacks.
