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.

NEW: Inside the 24-hrs before WH slapped export controls on Anthropic - Last Thursday, Amazon CEO Andy Jassy raised concerns about Fable jailbreak to Trump admin - Friday AM, Sean Cairncross, Bessent, Susie etc. held WH call to discuss - Then White House started reaching out to Anthropic to speak with Dario Amodei, who was at a wellness retreat. - When Amodei was finally available past 1pm, he had three tense phone calls with a combo of ppl including Cairncross, Bessent, Lutnick, Kessler, Will Scharf, Richard Walters, and Walker Barrett. -Amodei tried to clear up what he assumed was a misunderstanding. He defended the guardrails and distinguished between universal and non-universal jailbreak - Cairncross and Bessent were unmoved and asked Amodei to take down Fable and work with the admin to fix the vulnerabilities. (A WH official said Amazon’s findings were run past the NSA and they felt they had “proof.”) - Amodei asked for more time and info, but he made no commitments to pull the model - Bessent told Amodei directly at one point that he was making a “bad decision” - By Friday evening, the Trump admin imposed its export controls. - “Export controls were a last resort after begging them for hours to work with us,” senior WH official said.

Unless this changes, OpenAI researchers on visas need to plan for the fact they’ll probably lose access to internal models, and therefore their ability to do their jobs moving forward, sometime in the next couple months. I hope the company acts to prevent that.

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. Read our full statement: anthropic.com/news/fable-myt…

Some people are defending Anthropic despite everything that is happening, largely because Fable 5 is an amazing coding model. I can confirm this is true, and I do not think anyone would seriously argue against it. Even its high cost should not be an issue. We live under capitalism, and companies can charge what the market allows. But, and this is a very big but, there is a much more important issue here. What these people do not understand is that Fable will be the best coding model only for a short while. Others are very close behind. In fact, even better models will arrive soon, and coding itself is clearly on the path to being largely solved. Models will then become cheaper over time. If you do not get to build your amazing software a few months earlier, that probably will not change much in the world. At most, it may delay your personal ability to benefit from it for a while. It might even benefit you, by saving you from wasting money and time before better and cheaper versions arrive. But a doctor cannot wait to treat patients. A scientist trying to cure cancer does not have the luxury of waiting months. Every day of delay in research and clinical applications costs lives, potentially thousands of them. Every day that scientists around the world are denied access to the best models is another day the world is delayed from becoming better. And this is not only about model access. Anthropic has also advocated for pauses and regulatory capture. They are strongly against open models. In my view, this is not driven by some pure concern for humanity, but by the fact that such control would give them more money, more power, and more leverage over the future. Therefore, I believe it is far more important to be principled and stand for humanity than to chase short-term personal benefit. That is the reason for my outrage against Anthropic. It is nothing personal against poor Fable 5, or against the great AI engineers at Anthropic who are building these models. I do not doubt that many of them are sincere, and I am grateful to all frontier AI engineers who are pushing this technology forward. But I do hold those in charge of Anthropic responsible. Their founders and leadership should be held accountable for what I see as self-serving and deeply misanthropic actions. I also do not think they care. Not one of them has meaningfully responded to the outrage. This is also a note to everyone who keeps claiming that AI itself is the threat to human existence. No. It is not AI itself. It is the humans who control AI who may become the real threat to humanity, as I have said repeatedly. We have to resist this power capture at all costs, if we truly care about the rest of humanity.

Claude 4.8 and Fable 5, without a doubt, formulates their responses in a dense form that isn't ideal for human consumption. This is your tell that you need to begin deep dives by constructing domain-specific language and having the LLM constrained to that domain. This is why, a while back, I came up with this book so you can bootstrap your own DSL. intuitionmachine.gumroad.com…

If OpenAI does drop token pricing, this is likely because they’ve heard from customers they can’t adopt AI at volume at the current pricing. Margin is high now for served tokens. They could cut prices by like 60% and still be profitable imo

Trump says he thinks AI companies will agree to 'giving back' to the public

It’s coming wether you like it or not

ANTHROPIC ANNOUNCED THAT MYTHOS 5 AND FABLE 5 MODELS WILL COST $10 FOR EVERY MILLION INPUT TOKENS AND $50 FOR EVERY MILLION OUTPUT TOKENS.

Anthropic, OpenAI and Demis are all in favour of preparing a coordinate pause of frontier AI development. Skate to where the puck will be people, not where it is now. This is a fast puck.
