This allegedly was triggered by a successful jailbreak of Mythos by an unnamed group who reported it to the government. We will hopefully get details soon.

I’ve had a number of conversations with folks inside and outside government about the current situation with Anthropic, and here is what I believe to be true:
— As we know, Anthropic publicly released its Mythos class models earlier this week under the commercial name Fable.
— Fable is Mythos with guardrails. But if those guardrails fail, then you’ve exposed Mythos and its advanced cyber capabilities to people who shouldn’t have them. (Keep in mind that Anthropic itself widely promoted the idea that Mythos was a cyberweapon and needed to be regulated as such. They asked for government regulation of Mythos and championed the guardrails on Fable. If there is a vulnerability — big or small — it is Anthropic’s responsibility to patch.)
— A highly credible trusted partner of both Anthropic and the USG who was testing Fable came forward with a jailbreak of those guardrails. The Admin asked Dario to fix the jailbreak or de-deploy the model. Dario refused.
— In their blog post, Anthropic defended its decision by saying the jailbreak isn’t serious. That is not what the trusted partner and the USG believe; nor is that kind of minimizing language consistent with Anthropic’s brand as the AI safety company. It’s difficult to fathom how they could claim a jailbreak allowing operability of a cyber weapon could be defined as not “serious.”
— In the past, Anthropic has always said that safety must be top priority and taken super seriously. In this case, Anthropic prioritized the continued offering of the consumer model over safety.
— In reaction, the Admin issued the export control. The Admin did this reluctantly. It’s been very surprised that Anthropic hasn’t wanted to cooperate with a reasonable safety request (ie fixing the jailbreak issue). Anthropic’s reaction is very much at odds with their branding and ethos as a safe AI research community.
— The Admin’s hope now is that Anthropic remediates the safety issue, the export control is lifted, and Fable goes back into general release. The Admin wants all of this to happen as soon as possible. It is frankly bewildered that Anthropic hasn’t wanted to comply with safety requests that it previously said were its highest priority.
— Those trying to misdirect and tie this action to the prior DoW/Anthropic issues are wrong. The Admin values Anthropic’s technical capabilities and feels that this issue, while serious, should be easily resolved. The ball is in Anthropic’s court.

The takeaway from Fable 5 being BANNED by the government: GET GOOD AT LOCAL MODELS SO YOU HAVE 100% CONTROL.
My entire weekend was going to be building my craziest ideas with Fable 5. That's now cancelled.
So instead of building with Fable this weekend, I've decided I'll go deep on local models:
1. Start with the runtime. Download Ollama or LM Studio first. This is the thing that actually runs models on your machine.
2. Match the model to your hardware. A model's size is measured in billions of parameters (7B, 32B, 70B). Bigger is smarter but needs more memory. Rule of thumb: a 7B model runs on almost any laptop, a 32B needs a good Mac with 32GB+ RAM, a 70B needs serious hardware like a DGX Spark or a maxed-out Mac Studio.
3. Know which model for which job. Qwen 3 is the best all-around choice for most tasks. DeepSeek for reasoning and coding. Gemma 4 when you need something tiny that runs on a phone. Llama when you want the biggest community and the most fine-tunes.
4. Quantization. You can shrink a model to run on weaker hardware with barely any quality loss. Look for versions labeled Q4 or Q5. This is how a model that "needs" a server runs on your laptop. Learning this one concept changes everything.
5. Connect it to your agent. Point Hermes or your agent stack at a local model.
6. Context window is your real constraint locally. Cloud models give you huge context for free. Local models make you pay for it in memory. A bigger context window eats RAM fast. Keep your sessions tight and your prompts lean or your machine chokes.
7. Learn to give local models tools. A smaller local model with web search, file access, and code execution beats a giant model with none. The capability gap closes fast when you wire up the right tools. The model is the engine but the tools are the wheels.
8. Fine-tuning is more accessible than you think. You don't need this on day one, but know it exists. You can take an open model and train it on your own data so it gets good at your specific domain.
I'll probably do a breakdown at some point on this @startupideaspod if people are into it.
The lesson from this ban is basically don't build your entire workflow on something that can disappear with a single letter. Own part of your stack. Local models are insurance.
It reminds me when people realized they don't own social media accounts. And then you saw people build email lists etc.
I remember running a startup and my biggest traffic source was organic FB. All of a sudden, algo changed, and I lost 99% of my traffic.
Same sorta moment (but bigger) for AI.
This is a wake up call.

Assuming Anthropic is able to restore Fable in the next few days, there's literally zero point doing any meaningful work until it is back.
What can be done in 100 hours with Opus can be done in 1 with Fable.
Hopefully this is figured out quickly.
Anthropic@AnthropicAI
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.

This post by @DavidSacks about the Anthropic/Fable situation is noteworthy, but not for the reason most people think.
Put the details aside for a second.
Anthropic released a blog post with their side of the story a few hours ago. David is responding with a bullet point list in a tweet about a different side of the story.
Years ago both sides would be jockeying to get mainstream reporters to tell their version of the truth and the American public would be fed some edited narrative that was filtered through a bureaucratic media organization.
That world doesn't exist anymore.
Now both sides share their versions publicly so the American people can hear directly from them. It is up to the individual citizens to make up their mind who they believe.
I haven't read a single article about the situation, but rather just read the various players' statements.
Fascinating how fast the world has changed.

contrary to the default reaction on this little website, this is absolutely incredible news for anthropic.
i mean obviously yes, the operational disruption is real. but public & world perception wise, this could not be a bigger home run. could be a grand slam type situation.
the fucking united states govt just looked at their model & effectively said.. yeah this shit is too powerful. you simply cannot buy that kind of aura. it elevates every other product by the company & it instantly reframes anthropic’s work as strategically significant, nationally relevant, & qualitatively different from the rest of the field.
there is not a single institution on the planet that can buy or orchestrate this type of significance.
absolutely ridiculous.

Worth reading very carefully.
SightBringer@_The_Prophet__
⚡️This is a monster signal.
This is the moment frontier AI stops being treated like software and starts being treated like controlled strategic capability.
The key phrase is not “customers.”
The key phrase is “foreign national Anthropic employees.”
That means the state is no longer only controlling chips, model weights, or overseas access. It is moving into cognition access by nationality. That is the real threshold. The U.S. government is saying the highest models are sensitive enough that even people physically inside the United States, working inside the company, may be barred from touching them if their nationality creates deemed-export risk.
That is weapons-control logic.
This is ITAR logic for intelligence.
The corporate language about a “misunderstanding” is probably diplomacy.
Companies say that when they need to preserve customer trust, employee morale, and regulatory room. But national security authorities do not force emergency suspension of top model access because someone made a minor paperwork mistake.
Something about Fable 5 and Mythos 5 crossed the line: cyber capability, autonomous R&D acceleration, AI-improving-AI utility, bio/security planning, code exploitation, or some blend of all of it.
The U.S. state just showed that Anthropic does not fully control Anthropic’s frontier layer.
That is the phase change.
Labs can brand themselves as public-benefit AI companies. They can talk about safety. They can sell enterprise plans. They can publish model cards. But once the models become national capability, the sovereign arrives. The state does not need to own the company to control the access surface. It only needs legal authority over export, security, procurement, and liability.
This confirms the arc we’ve been tracking:
Frontier AI becomes state-supervised strategic infrastructure.
Public AI splits from strategic AI.
Foreign access gets restricted.
Labs become quasi-defense contractors.
Model access becomes a national security perimeter.
Enterprise customers learn that API access is not property. It is revocable permission inside a sovereign-controlled stack.
The most important implication is organizational.
If foreign national employees can be cut off from frontier systems, AI labs now have to reorganize internally around citizenship, clearance, compartmentalization, and controlled access. That breaks the old Silicon Valley assumption that global talent can freely collaborate around the frontier. The next AI lab structure looks less like Google in 2015 and more like a defense prime crossed with a classified research facility.
For markets, the winners are the national champions with U.S.-aligned infrastructure, cleared customer channels, government relationships, compliance capacity, and domestic compute. The losers are open access, foreign-dependent AI wrappers, offshore model distributors, and any enterprise whose moat depends on unrestricted access to frontier APIs.
For geopolitics, this is escalation. China will read this correctly. Allies will read this correctly. Every serious state will understand that frontier models are now part of national power.
The AI race just moved from “who has the best chatbot” to “who controls cognition as a strategic asset.”

Chamath Palihapitiya@chamath
If a Treasurer of a Fortune 1000 company kept all of their cash in one bank they’d be fired for incompetence.
Similarly, if the leadership of a Fortune 1000 company bets the farm on only one frontier lab and their models you’re taking a lot of risk. This risk compounds as the labs’ intentions and public actions are bewildering and show them to be increasingly unpredictable.
This is why every major enterprise needs a model agnostic “control plane”. Get the work done, increase the productivity, make more money, save costs, increase efficiency but do it with governance, auditability and control.
Capabilities across all models are converging. Open source prices are, in some cases, 1/100th of the frontier labs. But governance, control, compliance and collaboration capabilities don’t exist unless you first focus on the right “control plane”.
If you do not find such a “control plane”, you’re increasingly taking risk as the frontier labs become increasingly unpredictable.
This is why 8090’s Software Factory is used this way in every major part of the economy including governments.

Interesting: According to David Sacks’ opinion, the fault lies with Anthropic (specifically CEO Dario Amodei). He argues that:
• Anthropic released Fable (Mythos with guardrails) but refused the U.S. government’s reasonable request to fix a confirmed jailbreak that could expose advanced cyber capabilities.
• They prioritized keeping the consumer model available over addressing the safety issue, which directly contradicts their long-standing public branding as the “AI safety company.”
• The administration only issued the export control reluctantly after Anthropic declined to cooperate, and Sacks emphasizes that the ball is now in Anthropic’s court to remediate the problem.
It’s getting more interesting minute by minute.

Anthropic Just Shot Itself in the Foot
Anthropic launched Fable 5 and Mythos 5, then watched the US government shut them down three days later. The same government their CEO Dario Amodei has been begging for years to regulate AI harder. Now he got exactly what he asked for.
This is straight-up leadership failure. Dario spent all that time pushing for rules and oversight. Those rules just killed his flagship models overnight. Customers in the middle of builds got cut off. Security teams using the models to find vulnerabilities suddenly had nothing. The company tried to call it a narrow export control thing over a jailbreak, but nobody is buying that spin.
I helped move big clients off Anthropic the same night. One account alone was worth millions a month. They switched to local open-source models and they are not coming back.
This is going to leave permanent damage. Customer exodus, key people leaving, and their IPO plans looking dead by the end of summer.
This hurts US AI competitiveness and national security work. It pushes people toward open-source options, including ones from China.
All because Anthropic positioned itself as the “safe and responsible” company that wanted government help. Now that help just flipped the off switch on their best stuff.
Let’s run through Dario’s greatest hits of fear-mongering and delay tactics, because the pattern is ridiculous:
• Back in 2019 at OpenAI, he helped push the call that GPT-2 was too dangerous to release fully. The world needed time to prepare, they said. It eventually came out anyway, and here we are. Did the sky fall?
• He left OpenAI to start Anthropic, preaching “safe” AI with heavy guardrails, Constitutional AI, and all the rest.
• Then came the endless public pleas for pauses, regulations, government audits, FAA-style oversight, export controls, and the power to block deployments. Essay after essay warning about risks while his company kept scaling.
• Right up to recent weeks, Dario was still out there calling for stronger rules, pauses on frontier models, and giving governments the kill switch.
And now? His own Mythos-class models get yanked by the bureaucracy he helped invite in. The clown show is complete. This is ridiculous.
In two years, everyone will have Mythos-class AI — or better — running in their pocket, on their devices, with no guardrails, no corporate nanny filters, and no remote kill switch.
Local, open-source, unstoppable. History is going to laugh at this entire episode: the CEO who spent years slowing everyone down only to watch his own company self-destruct by inviting the regulators to the party.
Dario wanted regulation. He got it. The rest of the industry gets the lesson: inviting the state into your tech is a fast way to lose control of it.
Centralized models like this are too fragile.
Open-source and local alternatives just picked up a lot more users who will never trust a company like Anthropic again.
This whole mess was completely avoidable. Hubris dressed up as safety advocacy.
Now the bill is due.

This is big: all access to Mythos and Fable AI models disabled for everyone outside America.
First thoughts:
1. Technology is the ultimate weapon. National sovereignty, national security, all of it is now about technology.
2. Globalization is dead and Bharat must find her own way ahead.
We must keep these two ideas in mind.
What can our government do right now? Ensure that orgs in India embrace smaller models, both Indian and Chinese open source ones. With a bit of effort, we can make them work. Anyway, why pay money to people who don't even want to sell to you?
We must deepen our R&D. Sarvam has been on it and we have been on it but remember that the latest models cost not only huge GPU budgets to train, the GPUs themselves are restricted. So we can't afford the scale of money (of the order of $100+ billion to even get in the game!) and even if we could come up with the money, we can't get all the GPUs. I would not like to ask the government to fund tens of billions of dollars on this anyway - the money has far better uses.
Zoho has been pursuing alternative R&D approaches that are far, far less expensive but by its nature cutting edge R&D takes time and we are patient. I am confident we will get there.
Any remaining people in India who have delusions about globalization should wake up now.

— In the past, Anthropic has always said that safety must be top priority and taken super seriously. In this case, Anthropic prioritized the continued offering of the consumer model over safety.
— In reaction, the Admin issued the export control. The Admin did this reluctantly. It’s been very surprised that Anthropic hasn’t wanted to cooperate with a reasonable safety request (ie fixing the jailbreak issue). Anthropic’s reaction is very much at odds with their branding and ethos as a safe AI research community.
— The Admin’s hope now is that Anthropic remediates the safety issue, the export control is lifted, and Fable goes back into general release. The Admin wants all of this to happen as soon as possible. It is frankly bewildered that Anthropic hasn’t wanted to comply with safety requests that it previously said were its highest priority.
— Those trying to misdirect and tie this action to the prior DoW/Anthropic issues are wrong. The Admin values Anthropic’s technical capabilities and feels that this issue, while serious, should be easily resolved. The ball is in Anthropic’s court.

For anyone wondering what this means: - Anthropic (and potentially future OpenAI, Google, xAI) models that cost billions to develop will make 0 revenue outside the US - a big double digit percentage of Anthropic (and potentially OpenAI, Google, xAI) workforce can no longer work there, because they are foreigners and are not allowed to use those models
So Trump just made frontier model development effectively unprofitable and tremendously slowed down Anthropic (and potentially others in the future)
He's handing China the win on a gold platter.
*potentially: if the same restrictions are imposed on other frontier labs and models
Anthropic@AnthropicAI
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.

BOOM WHO BROKE MYTHOS AND SPILLED THE BEANS!
Justice Served: Amazon Researchers Hands Anthropic a Brutal Reality Check via Uncle Sam
Take a seat as this is getting ridiculously interesting!
Oh, the sweet, spicy irony. Anthropic the self-proclaimed AI safety saints who love lecturing everyone about doomerism, existential risks, and how their god-like models need heavy guardrails because think of the children (and China) just got absolutely hoisted by their own petard.
And the blade?
Courtesy of Amazon.
Here’s the timeline:
Anthropic drops Fable 5 and Mythos 5 — their shiny new cybersecurity beasts hyped as capable of sniffing out software vulnerabilities like a bloodhound on steroids, but with “safe” wrappers for the public. They pat themselves on the back for responsible release… while quietly expanding access and flexing those offensive cyber chops to governments and partners.
Enter Amazon researchers (yes, from the company that’s poured billions into Anthropic and hosts their models on AWS).
They cook up some clever prompts, jailbreak Fable 5’s safeguards, and get it to cough up details on real security vulnerabilities. Not a full apocalypse unlock just practical bug-hunting stuff that defenders would actually use.
Wall Street Journal reports: They document it and, instead of a polite responsible disclosure to their “partner,” it ends up in the hands of the US government.
They did the right thing ethically and legally.
And Boom.
Commerce Secretary Howard Lutnick drops an export control hammer faster than you can say “national security.” Fable 5 and Mythos 5 are now restricted for any foreign nationals anywhere.
Anthropic, unable to magically geo-fence API keys or fire their own non-US staff on the spot, yanks access for everyone worldwide. Models dead. Users stranded. Dario Amodei’s team spits out a 700+ word cope-blog claiming it’s a “narrow, non-universal jailbreak,” no big deal, other models do it too, and the government overreacted.
This is poetic justice at its finest. For years, Anthropic has positioned itself as the virtuous alternative — heavy on the fear-mongering, light on actually shipping unrestricted power, all while cozying up to Big Tech investors and government contracts.
They warned the world their tech was too dangerous… then released it anyway with theatrical safeguards. Now a competitor-investor (Amazon) demonstrates exactly why you don’t hype your model’s cyber-offense potential like it’s a nuke and expect zero blowback.
The Trump admin, already feuding with Anthropic over Pentagon terms and “woke doomerism,” wasn’t in the mood for nuance. Export controls deployed. Models grounded. IPO dreams just got a very public haircut.
Lesson?
Play the safety piety card (going to the Pope!) too hard in the AI arms race, and eventually the grown-ups (or rival labs with government ears) will take you at your word.
Amazon didn’t even need to go full saboteur they just showed the receipts.
Anthropic’s own hype and hedging came back to bite them in the most humiliating way possible: sidelined by their investor while the rest of the frontier keeps shipping.
Schadenfreude level: maximum. The “responsible” lab that cried wolf just got muzzled by the very system they helped politicize. Pass the popcorn this AI drama is far from over.

Anthropic Just Shot Itself in the Foot
Anthropic launched Fable 5 and Mythos 5, then watched the US government shut them down three days later. The same government their CEO Dario Amodei has been begging for years to regulate AI harder. Now he got exactly what he asked for.
This is straight-up leadership failure. Dario spent all that time pushing for rules and oversight. Those rules just killed his flagship models overnight. Customers in the middle of builds got cut off. Security teams using the models to find vulnerabilities suddenly had nothing. The company tried to call it a narrow export control thing over a jailbreak, but nobody is buying that spin.
I helped move big clients off Anthropic the same night. One account alone was worth millions a month. They switched to local open-source models and they are not coming back.
This is going to leave permanent damage. Customer exodus, key people leaving, and their IPO plans looking dead by the end of summer.
This hurts US AI competitiveness and national security work. It pushes people toward open-source options, including ones from China.
All because Anthropic positioned itself as the “safe and responsible” company that wanted government help. Now that help just flipped the off switch on their best stuff.
Let’s run through Dario’s greatest hits of fear-mongering and delay tactics, because the pattern is ridiculous:
• Back in 2019 at OpenAI, he helped push the call that GPT-2 was too dangerous to release fully. The world needed time to prepare, they said. It eventually came out anyway, and here we are. Did the sky fall?
• He left OpenAI to start Anthropic, preaching “safe” AI with heavy guardrails, Constitutional AI, and all the rest.
• Then came the endless public pleas for pauses, regulations, government audits, FAA-style oversight, export controls, and the power to block deployments. Essay after essay warning about risks while his company kept scaling.
• Right up to recent weeks, Dario was still out there calling for stronger rules, pauses on frontier models, and giving governments the kill switch.
And now? His own Mythos-class models get yanked by the bureaucracy he helped invite in. The clown show is complete. This is ridiculous.
In two years, everyone will have Mythos-class AI — or better — running in their pocket, on their devices, with no guardrails, no corporate nanny filters, and no remote kill switch.
Local, open-source, unstoppable. History is going to laugh at this entire episode: the CEO who spent years slowing everyone down only to watch his own company self-destruct by inviting the regulators to the party.
Dario wanted regulation. He got it. The rest of the industry gets the lesson: inviting the state into your tech is a fast way to lose control of it.
Centralized models like this are too fragile.
Open-source and local alternatives just picked up a lot more users who will never trust a company like Anthropic again.
This whole mess was completely avoidable. Hubris dressed up as safety advocacy.
Now the bill is due.

Imagine being a bigger bitch about safety than anthropic lmao
David Sacks@DavidSacks
I’ve had a number of conversations with folks inside and outside government about the current situation with Anthropic, and here is what I believe to be true:
— As we know, Anthropic publicly released its Mythos class models earlier this week under the commercial name Fable.
— Fable is Mythos with guardrails. But if those guardrails fail, then you’ve exposed Mythos and its advanced cyber capabilities to people who shouldn’t have them. (Keep in mind that Anthropic itself widely promoted the idea that Mythos was a cyberweapon and needed to be regulated as such. They asked for government regulation of Mythos and championed the guardrails on Fable. If there is a vulnerability — big or small — it is Anthropic’s responsibility to patch.)
— A highly credible trusted partner of both Anthropic and the USG who was testing Fable came forward with a jailbreak of those guardrails. The Admin asked Dario to fix the jailbreak or de-deploy the model. Dario refused.
— In their blog post, Anthropic defended its decision by saying the jailbreak isn’t serious. That is not what the trusted partner and the USG believe; nor is that kind of minimizing language consistent with Anthropic’s brand as the AI safety company. It’s difficult to fathom how they could claim a jailbreak allowing operability of a cyber weapon could be defined as not “serious.”
— In the past, Anthropic has always said that safety must be top priority and taken super seriously. In this case, Anthropic prioritized the continued offering of the consumer model over safety.
— In reaction, the Admin issued the export control. The Admin did this reluctantly.

The Admin wants all of this to happen as soon as possible. It is frankly bewildered that Anthropic hasn’t wanted to comply with safety requests that it previously said were its highest priority.
— Those trying to misdirect and tie this action to the prior DoW/Anthropic issues are wrong. The Admin values Anthropic’s technical capabilities and feels that this issue, while serious, should be easily resolved. The ball is in Anthropic’s court.

pro regulatory capture anon finds out regulatory interference is bad if the government is ideologically different than you
Tenobrus (→vibecamp)@tenobrus
- i'm angry about this because i personally and for others want access to fable, and simultaneously believe anthropic's safeguards were sufficient and the US government badly misunderstood the information they were presented - but in abstract this is in fact exactly what I want. it's heartening to see the USG treat artificial intelligence with the seriousness and immediacy it deserves. this kind of swift action is what might have a chance of saving us from unaligned RSI. - but i also very much don't trust *this* government to handle this well, to take sane unilateral action, to chart any kind of correct path. - and this escalates the global race enormously. this is as strong a signal as you can get to, not just China but the EU and even our closest allies, that the US will not be sharing this advantage. that if they want sovereignty they're going to have to fight for it - obviously, that was always the case, and it was always going to happen eventually. but i don't think now was the time to send that signal. it would have been better to delay as long as possible.
very mixed feelings today
