Anthropic Blocks Foreign Access To Fable 5, Mythos 5 After U.S. National Security Order

About four days after Anthropic released Claude Fable 5, a next-generation "Mythos-class" AI model, the frontier AI lab led by Dario Amodei revealed late Friday that it was disabling foreign customers' access to these cutting-edge models, citing an export-control directive from the federal government.

"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," Anthropic wrote on X around 9 p.m. ET.

The AI lab's website stated that the federal directive was received around 5:21 p.m. ET. To ensure compliance, the lab was forced to shut off Fable 5 and Mythos 5 for all customers.

Anthropic continued, "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."

Anthropic pointed out that it understands the government's concern centers on a potential method of bypassing, or "jailbreaking," Fable 5.

Dario's company laid out some of Fable's safeguards:

  • We have instituted strong safeguards that greatly reduce the likelihood that Fable is misused for tasks related to cybersecurity (among others). In fact, our safeguards are so strong that many users have complained that they are overly broad.

  • In the weeks leading up to the launch of Fable, Anthropic worked with the US government, the UK AISI, multiple private third-party organizations and internal teams to red-team Fable's safeguards for thousands of hours in total.

  • These tests showed that Fable's safeguards are substantially more effective than those of any previously deployed model.

  • No testers have yet been able to find a universal jailbreak—a jailbreak method that can very broadly bypass the model's safeguards, unblocking a wide range of cyber capabilities.

  • 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. We stated this clearly when we released Fable 5.

  • 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 (in the case of non-universal jailbreaks) or very expensive to produce (in the case of universal jailbreaks), and to combine this with thorough monitoring to quickly detect and shut down any successful attacks. This is also why Anthropic has required 30-day retention of customer data with Fable—a policy change that carries real costs for us with customers, but that allows us to research and mitigate jailbreaks.

  • We stand by this defense in depth strategy. It reduces the risks posed by Fable, making them comparable to the risks of existing models already deployed across the industry.

  • We have not even received a disclosure of a concerning non-universal potential jailbreak that led to a harmful result. The potential jailbreaks that have been disclosed to us are either entirely benign responses or are minor findings that provide no Mythos-specific uplift.

Jailbreak concerns already out in the X universe? 

this is definitely what got fable banned https://t.co/3b0rmIIdLe

Last week, shortly after Tuesday's Fable release, BMO analyst Brian Pitz told clients, "We maintain that Anthropic is the leading pure-play AI lab, combining best-in-class model intelligence with its cutting-edge, benchmark-leading Claude Fable 5 frontier model released June 9, 2026; with clear commercial traction and momentum in its enterprise offerings."

Pitz said, "Anthropic's strengths are particularly evident in coding, agents, and enterprise, where Claude has emerged as a leading model powering tools such as Claude Code and Cowork, both of which have scaled rapidly. This reinforces the company's advantage in translating model intelligence beyond benchmark performance into viable, real-world applications—what we view as the next key battleground in AI."

The release of Claude Fable 5 prompted Pitz's team to declare, "While it is too early to crown a winner among foundation models, we see Anthropic and OpenAI as the leading pure-play AI labs today."

Britain Goes Full 'Airstrip One'

Britain Goes Full 'Airstrip One'

Authored by Stephen Green via PJMedia.com,

In George Orwell's 1984, Great Britain was just a province of Oceania named "Airstrip One" as a none-too-subtle nod to the U.K.'s role as host to the heavy bombers of U.S. Eighth Air Force during World War II.

Four decades past the real 1984, and there's still no Oceania. But Britain looks more and more like Airstrip One as Parliament considers a bill opening up everyone's smartphone to government supervision — and jail time for tech execs who don't submit.

You had to figure this was probably coming, right?

Right.

Reclaim the Net reports that "Ministers are reportedly drafting a law that would force Apple, Google, and the rest to make it impossible for a child to send, receive, view, or share a single nude image, with the executives who refuse facing up to five years in prison."

That might sound all well and good, but as usual, For the Children™ is little more than the government's justification for total surveillance.

"You cannot block every naked picture someone might stumble across without inspecting every picture, every message, every video call, every streamed film, on every device, all the time," Reclaim noted, with nudity serving as "the excuse and the unbroken view into your phone is the actual prize."

The industry term is "client-side scanning," which sounds much nicer than "a government mandated app that looks at everything on your phone all the time."

And even that sounds better than "Big Brother is Watching You," which is exactly what it is.

As already required by Britain's Online Safety Act, Apple and Google forcibly install age verification on every iPhone and Android device in the UK via app store updates.

No, it can't be uninstalled.

As I reported in January, what this means in practice is that London's Office of Communications ("Ofcom" in Newspeak) mandates on-device software able to read everybody's "private" messages in real-time and scan their images, too, before any personal encryption tools come into play. 

London pinky-swears that it'll only look for CSAM and terrorism-related materials, but as the Telegram's Zia Yusuf put it back then, "the slippery slope is obvious" and "mission creep is inevitable." The country looking to ban traditional chef's knives (really!) in the name of safety simply cannot be trusted with this much digital power.

Nobody can, really. 

The way things work now, if you don't pass the mandatory age check, the iPhone software bars adult websites on every installable browser, and the Communication Safety feature scans every AirDrop, FaceTime, Messages, and photo for nudity, blurring whatever it catches. And the Android filter works in a similar way.

All For the Children™, naturally. 

But as Reclaim also pointed out, client-side scanning is "a general-purpose content scanner pointed at one target this year and swivelable toward any other the next, a flyer for the wrong march, a banned book, a face the Home Office has taken against."

Now that the software is installed, Parliament can authorize the Home Office to ignore the age check and look for whatever it wants to on literally everyone's device. That's exactly what Parliament wants to do next.

Orwell envisioned ever-present two-way telescreens mounted on almost every wall that could only try to monitor everyone all the time. He never envisioned a telescreen that people would pay good money for, carry around 24/7, and trust with their every notion and secret.
