It looks like the house of cards has finally started to do its thing.

First time we've seen a model company get their arm twisted this hard by the gov.

This is another historical moment in AI.

Well, I guess we know whose side they’re on.

At least on Claude Code it's completely useless. It tells me to run all the commands myself cause it's blocked ("Classifier's blocking me again" lol). Just tried now and saw the msg: "There's an issue with the selected model (claude-fable-5[1m]). It may not exist or you may not have access to it. Run /model to pick a different model."

I really have no clue how Anthropic released this thing without doing any real testing. I did use it on claude.ai with no issues; talking just for code.

This heralds the end of frontier model development in the US since the same national security argument can and will be made against any model stronger than Fable/Mythos. Squashing the ability of Anthropic and OpenAI to deploy newer stronger models will destroy their valuation so no trillion dollar IPOs either. Low cost Chinese models will soon catch up to Opus and GPT-5.5 eroding Anthropic and OpenAI's ability to charge more. The knock on effects of this are just beginning.

gaigalastoday at 3:10 AM

Man, Opus 4.8 is feeling a lot smarter in the last few interactions. Is Anthropic silently serving Fable as Opus just to stick it to the man?

ai_fry_ur_braintoday at 3:01 AM

These guys are working with the feds. This is a giant psyop from the start. Make Anthropic look like they're harnessing dangerous powers, portray them as counter to government.

They aren't counter to the government, this is all kayfabe to introduce precedence for the US government to be justified in putting controls on AI, expect that by the end of the month there are discussions to regulate Deepseek.

It could be the case that Anthropic created this whole situation on their own, I figured they'd release a "dangerous" model at some point then piggy back off of bad outcomes to dig their regulatory moat

It could also be the case that Altman has close ties to the white house and is using regulatory levers on his competion.

I stand by that its all Kayfabe to make AI look more dangerous than it is (it cant even center a div reliably) to justify controls on Open Source.

Fable is very impressive but not exports restriction impressive. Very tinfoil hat on my part but doesn't this seem very false flag adjacent?

You bribe someone in the admin to restrict access after a couple of days of media blitz and user approval, locking in the honeymoon period that new model releases get (remember when GPT-4 was new?). The spooky factor gives it even more marketing, and just before the IPO the Trump admin frees Mythos and they make nice after the DoD debacle.

Why not open it to US nationals?

I think it's interesting they think it's about jailbreaking when it could be about the guardrails or even other stuff being reported like it deleting people's projects depending on what they were working on.

The party of big government at it again.

mrcwinntoday at 2:04 AM

Gosh I sure hope OpenAI had nothing to do with this. That would be awfully surprising.

halyconWaystoday at 1:48 AM

So the US government wants Anthropic to require IDs from their users, driving them to over platforms, but won't require this from OpenAI?

Download the open weight models while you can

nickhodgetoday at 1:40 AM

Well, kids, it looks like we're back to closing those tickets the old fashioned way.

By thinking for ourselves and writing the code with the keyboard.

tamimiotoday at 1:28 AM

So scare tactics on losing jobs and ending all white collar ones is fine and ok and advertised everywhere, but scare tactics about software vulnerabilities is not and forbidden, got it!

sigbottletoday at 3:09 AM

That's annoying. I shelled out a pretty penny specifically to try out Fable, but if I'm only going to get to use it for 2 days...

aussieguy1234today at 1:27 AM

While I'm always skeptical of the claims of AI companies and have been skeptical of Anthropics claims about the dangers of their Mythos model, the fact that the US government is taking this seriously enough to send this type of order is strong evidence in their favor.

catigulatoday at 1:20 AM

Begun, the AI wars have.

qudattoday at 2:19 AM

Excellent ad campaign by Anthropic

engineer_22today at 1:13 AM

> 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.

Laying the groundwork to limit access to high capability models

hendersoontoday at 1:11 AM

No actual proof of any kind. Obviously a petulant attack on Anthropic.

dmitrygrtoday at 12:59 AM

1. Lie about making thinking machines smarter than humans

2. Get treated like you actually did what you claimed, and face consequences

3. ???

4. Profit

nikolaytoday at 2:31 AM

Big deal! Can't wait for the Chinese models to catch up - cheap, no marketing gimmicks, no politics, humble, hardworking, and they are only getting better. America is no longer a trustworthy technology partner! No wonder Europe is trying to detach itself from the present and future Trumps, Pete Hegseths, and other deranged narcissists. But I wonder why Anthropic is cutting my access, too, as I'm a US citizen residing in America? They could've vibe-coded a self-improving ID verification in no time, right? Should US models in the future require biometric verification to make small CSS tweaks to a vibe-coded website?!

ks2048today at 1:42 AM

Trump must have run his extensive test suite and carefully weighted the dangers vs the legal implications.

epsteingpttoday at 2:39 AM

jimkleibertoday at 1:29 AM

How much of this is the dangers of the technology vs the dangers of saying no to the Trump administration?

CSMastermindtoday at 3:23 AM

Their entire marketing strategy has been unwarranted fearmongering. This is completely unsurprising.

angry_octettoday at 1:58 PM

This is all a Trump machine grift. He first tried with Hegseth and the DoD, but they didn't care because DoD is 0.1% of their market share. So now Trump is doing classic standover man tactics with more natsec equities bs.

Remember, it is all a grift.

bridgettegrahamtoday at 2:09 AM

this is just the US government bullying everyone wherever they can because they "are the bestest government that has ever goverend" ugh puke. the US govt and its leader is a typical schoolyard bully and I wish someone could stop that bully. i hate that the govts have so much power.

AbstractH24today at 2:32 AM

This might be the biggest favor to anthropics valuation that Trump could have done

mil22today at 4:38 AM

How totally absurd.

Why do people still want to build businesses in the US or in Silicon Valley? California taxes are already punishingly high, especially after recent rate increases and the 2017 cap on SALT deductions. And now we have a Machiavellian, authoritarian, fascist, tech-illiterate administration interfering with the operation of free markets.

I'm speaking rhetorically, of course. I know Silicon Valley still has the densest concentration of talent and venture capital. The network effects are real. But it is long past time for that to change. I hope entrepreneurs around the the world see this and think twice before moving to the US or starting a business there.

Perhaps they will. I used to work in Silicon Valley and was very much in demand. Now I run my own business from a tax-free state, and my income is high enough that moving back to California would impose a huge financial penalty. I am originally from Europe, and California's marginal tax rate is now so high that I would pay less tax back home. When I moved to the US, the opposite was true.

I'm sure I'm not the only one doing that calculation.

LogicFailsMetoday at 1:49 AM

Or this is Trump's gift to Elon on the day of his big IPO, only semi-joking.

whynotmaybetoday at 2:58 AM

So what now?

They'll make a book with mythos's code and sell it like Phil Zimmerman did with PGP?

Typical admin move here - give our foreign competitors as much time to catch up as possible.

Trumps solution to his Iran woes is it pick a different fight?

BayesStreettoday at 2:00 AM

it's over

ryanSrichtoday at 1:56 AM

So the moral of the story is, don't build a frontier model in the US. Got it.

jellyroll42today at 2:23 AM

Trump admin is helping them pump their IPO with this stunt

GreenSalemtoday at 2:09 AM

Time to switch to open weight Chinese models.

Any company that uses Magaland LLMs should be aware of the very real Trump related risk.

What happens if the LLM your firm runs on is disabled tomorrow, because Trump wakes up feeling slightly annoyed...
