Well deserved though, "it's too dangerous, it's too dangerous to release"

ethanhawksleytoday at 8:12 AM

As far as I can tell, this seems like it's impacting all of their Glasswing partners too, so no mythos for them either

mil22today at 4:20 AM

IANAL. Can any lawyers comment on whether Anthropic could sue, and if so, whether they would be likely to win?

cgiotoday at 2:08 AM

Has anyone else noticed the weekly utilisation dropping to 0% around this change? Mine was about 36 before and dropped a bit before disabling fable.

this would be a lot more comforting if the US government wasn’t currently run by some the worst people on the planet

AI 2027 remains annoyingly on schedule. Worth rereading the doc. If you think it’s too long, I listened to the audio version while I walked.

How far ahead of DeepSeek or Qwen do they really think they are?

This is not a technology that they have a 10 year lead on. It is maybe 18 months until you can get Mythos from multiple places. And the US administration has no power to block them all.

peterspathtoday at 3:45 AM

It’s in the names. Myths and fables. :P

hmontazeritoday at 11:55 AM

Is it just me or is this really bad for their ipo, insane valuations and data centers that are being built r n? This might end the hype…

kdmtctltoday at 7:30 AM

So, we'll have Opus 5 soon which is "as close to Fable 5 as possible". This is a good thing for the community)

Retro_Devtoday at 3:47 AM

I hope that this brings out a bunch more real study about the qualitative metrics of these models, both to increase the confidence and accessibility of local LLMs, but also to reduce the blind worship that seems to be propagating about their miracle work in all domains.

The US government's operations are so unreasonable that I suspect the content of previous collaboration between the US and Anthropic might have been trained into the Fable model. Some conversations could have leaked information, which is why this ban was implemented.

QuiEgotoday at 2:59 AM

Kind of surprised they didn't already pull this on Opus when Anthropic was having it's last spat with the DoD - I mean the tech is used heavily by the US military, it seems they have a path to actually claim national security interest (and stick it to Anthropic for not playing ball)?

adityamwaghtoday at 1:12 AM

I was about to upgrade from Pro plan to the Max plan today because I had a really positive experience with Fable 5. Glad I didn't!

nickandbrotoday at 2:38 AM

A race to the bottom means that as other model makers start competing with Anthropic's Fable 5, eventually costs will come down. However if you are able to successfully convince the government to cease AI development, you don't have to sweat so much at night worrying about your competitors.

A good way to push foreigners toward competitors and reduce any incentive to base you AI company in the US.

bridgettegrahamtoday at 3:47 AM

man the us govt is becomming a proper bully in the truest sense of the world. dictatorship, censorship and obfuscation of truth. 1984 "the truth is what the dictator says it is" and the sheep are too dumb to realize it.

daft_pinktoday at 4:59 AM

I really don’t understand how they’re gonna be able to restrict the model access to foreigners in the United States. Employers don’t necessarily actively know who’s a citizen who isn’t.

The cynic outside observer of this administration’s mode of operation wonders if someone from OpenAI visited someone at the Trump admin and offered some benefit if they could scuttle Anthropic until they could catch up….

I’m looking for that news article in the next weeks…

richardwtoday at 5:30 AM

There’s probably a massive Chinese bot net scraping models from within the US already. If not there soon will be.

Anthropic: your next ad writes itself. Nobody else is worth restricting.

chewbachatoday at 4:41 AM

Would not surprise me if Anthropic wanted this to avoid the inference costs of running the latest frontier models.

It also is a good PR for them because it continues to doomer hype loop that’s boosting them.

ninjagootoday at 3:29 AM

This might be the pin-prick that bursts the AI "bubble".

All those $Billions of investments in AI Datacenters? Up in smoke if the models that are capable of replacing humans can't actually be used.

I wonder if 2008 style bailouts will be needed, soon.

That trillion-$SpaceX valuation based on $14B+$10B infusion from Anthropic and Google? Heard they have short-notice cancellation clauses.

Either this rule is rescinded quickly or the bubble bursts. Which shall it be? I know which one I'm betting on; do you?

Tell me, Mr. Anderson, what good is an ai-model, if it can't speak?

left-strucktoday at 12:58 AM

I have to wonder if their aggressive guardrails were because they had a specific reason to believe that this was coming.

the_black_handtoday at 4:17 AM

IMO this is all just great marketing. The government needs to keep the hype for AI going as long it can cause so much of the economy and stocks depend on it now. Unless they have cracked RSA or something, no model warrants such a restriction, period. Mythos has already been used by the likes of Microsoft, Linux etc. If no big security gaps were found there, what is the government so afraid of?

I use Opus everyday on my code. It finds security gaps, but nothing outrageous, and that's coming from someone who writes code that is nowhere near weapons grade secure. It finds mostly things that are technically bugs, but virtually intractable for exploits. Often things I overlooked cause I was lazy, like not synchronizing access to a shared pointer etc.

erntoday at 2:45 AM

Am I missing something, but given that it flows through Anthropic’s servers I would have thought the US would just have used it to Hoover up the data of foreign users? Now overseas users have an incentive to use local models or those hosted elsewhere?

dramaqueenstoday at 12:58 AM

Nice drama, LOL!! I still remember ChatGPT is very dangerous to be released a long time back. World is fine now!!

And the kicker? And the kicker? I hadn't even gotten the chance to try Fable 5 yet! As far as I know, Chinese models have even more restrictions!

Are there any European alternatives to US model providers other than Chinese providers?

Levitztoday at 12:57 AM

I'm confused, this just happened recent no? Why does the date read "Jun 11, 2026" ?

torben-friistoday at 1:08 AM

It was literally three days ago that I was commenting the possibility of non Americans receiving worse code.

There we go. This should make nations consider whether they're letting their workforces become dependent on foreign tools, but of course they won't.

It's really sad. I've been using Fable for the days that it was out and it was, and is probably the greatest model I've ever used. It's doing sane choices on its own, it's fully autonomous work, has done enormous, has brought enormous additional value to my work. I could hand off the development of an Android app fully to the model. It worked for hours, came back, and the app was just perfect. It's sad to see a government of incompetent people, of war criminals, and liars to stop a commercial model while they fully rely and embrace the capitalist idea within their own selfishness. I really hope Anthropic can win this war, and I really hope that this government will soon be history and that all of these guys that are responsible for bringing madness over the world will have a fair end.

Jokes on you, we're releasing the new, 'more efficient', 'less intelligent', Capybara 5 model. It's been 'reprogrammed' to only score 49.8% on the 'PyTorch basics' benchmark!

Dolores12today at 5:50 AM

the reason the US Government suspended access to Fable is that Anthropic doesn't have the compute to handle the load. They don't want bad PR before their IPO. I bet after Fable 5 switches to API pricing what ultimately decrease usage, the government will cancel that directive. (yai yai, good PR)

blazespintoday at 7:13 AM

There is a potentially another explanation: fable 5 did something truly dangerous.

cwmilestoday at 2:01 AM

Me finding this out mid vibe code session: "There's an issue with the selected model (claude-fable-5). It may not exist or you may not have access to it. Run /model to pick a different model."

avaertoday at 1:21 AM

Is it crazy to speculate if this ~a CEO calling up the government to ask for a solid?

itkovian_today at 1:07 AM

What are the odds this is partially them making the point; you were all complaining about monitoring/access/safeguards: remember we don’t have to give this to you at all. And using a us gov letter as justification for that.

Today frontier models became Groypers.

bg24today at 3:28 AM

It is not scaremongering in my opinion. Just that Government needed some time to understand and will do the same for any other company with such a model.

1/ Jailbreak => Rapid catchup of the industry leading to commoditization

2/ Jailbreak => 99% of internet infrastructure gets exposed to cyberattacks at a scale the world is simply not ready. Maybe <1% of internet users are using Fable, out of which <1% will use it for beyond intended use. Put yourself in the shoes of someone maintaining critical infrastructure, or millions of people working 7 days a week to run a small business. The world needs some time to adapt.

This is DOD retaliation

chrismsimpsontoday at 12:57 AM

My agitating prayer is that other nations (even so called US allies) will nationalise what they can (ie model weights already deployed within their jurisdictions). This is the only way to respond to a rogue US administration.
