When I was considering joining Anthropic in 2023, their main pitch was “we have prioritized safety over commercialization and actually made decisions that hurt our business because they were the right moral choice.” Everyone I met at the company was incredibly sincere about their mission alignment. I’m cynical and don’t believe that some people joining Anthropic today would hold this position, but I do think the early team really believed in this mission.

Andrej Karpathy (not a US citizen), the top AI scientist at Anthropic, is now barred from accessing Anthropic's top AI model. This is beyond stupid. _

I'm told Anthropic is perplexed by the situation they are facing, so they've turned to @k8em0 to do their on-the-record rapid response. These people really just don't get it....

- 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

Anthropic had 90 minutes to take down Fable after Trump admin demand axios.com/2026/06/13/anthrop…

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 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…
