Presumably there are different levels of safety. I assumed Fable was a nerfed Mythos, and not just via safety harnesses but actual model degredation.

I don't think this is the case just because of the 'fallback' method they described, where suspicious requests are routed to Opus 4.8. If the model was degraded for certain categories of knowledge, then they'd probably be fine letting the model answer to it. IMO, of course

"Fallback" is only for LLM-training related requests (ie, ones that would compete with Anthropic (!))

For cyber and bio related requests it just refuses.

The damage is done. You cannot build a business critical function on top of American SOTA frontier model. Especially not with the current crew in charge. Now whether AI tech is in the same league as say Nuclear tech and therefore by any reasonable standard should be regulated is a different question. We hit the slippery slope on a random day in June 2026 and there is no putting the genie back in the bottle. Any exec…

LLMs are still easily replaceable. If the SOTA frontier model provides meaningful impact for your critical business function, then worse case you flip the switch to the next most capable model.

Unequivocally false. Models have different behaviors, parameters, tool calling templates, etc. The providers publish extensive documentation on all of this. Yes, you can take the quick way and swap a model, but it will not run at its full potential until you adapt your workflows to it.

No nation is going to willingly release a model that can be used against it. Not even China. The moment they have a Mythos class model, they will go through the same process. The AmericanCorp models are far ahead of any other models so we see this process unfolding through that lens. No Mythos class model will be allowed to be legally hosted for download on any service. All powerful nations will ban this since safegu…

Not great news for nations that want to secure their software.

They certainly are now that the export ban is lifted.

... Care to explain your thoughts on this? I'm absolutely fascinated.

So it seems like David Sacks was right that the US government only really got involved because the Amazon/ AWS CEO complained about latent security threats [0] and that the government was reluctant to actually issue the export control. [0] https://news.ycombinator.com/item?id=48529358

Sacks has said so many obviously false things in reference to government actions (Jan 6th, Ukraine, etc) that there is no reason to trust anything he says.

If the Trump administration wants him to say something, he says it. Maybe what he is saying is true, maybe it isn’t. There is no way to know.

The story they are telling is exactly the same whether it was true or they were just shaking down Anthropic for no reason.

The real problem in all this is lack of predictability. The White House is just making it up as it goes along. Investors, customers don’t know what the process is and can’t plan. In the end, we need actual laws that tell the market what kinds of models get paused / analyzed, how long that pause can be, etc. Otherwise there’s no standard and it will be easily abused and prevent investment in US AI companies.

There are laws and regs. Just because you’re not familiar with the Defense Production Act (50 U.S.C. § 4511 ), Export Control Reform Act, 50 U.S.C. § 4812 and others doesn’t mean that they don’t exist and apply.

Ha! But sorry, Dario has failed at this part of the job. It’s good that Tom is there and that there is plenty of other strong talent there.

Dario's job is to be a cheerleader. He likely does not have the domain knowledge nor is authorized to be the recipient of such a letter. And that's ok. His role is to hire others competent in export matters. It's a learning experience for them.

I think you are missing some context here.

One of the contributing factors that led to this control in the first place was that the commerce department couldn't get Dario on a call immediately:

"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."

Anthropic has disputed that Dario was at a wellness retreat but both sides seem agree that it seemed to be a problem (and it is very apparent that Dario's response made things worse).

This x 10 . I don’t understand how people are saying you can’t use LLMs to get crazy productivity gains. If you can’t write quality code with LLMs at ludicrous speed, you’re holding it wrong. You will have occasional bad days and regressions. But overall you’re still going to be able to 4x your progress.

I have plenty of experience with LLMs and use them daily but definitely wouldn't call generated code "quality code." Often looks like complete vomit.

That’s kinda what I mean. Maybe it only works well in some languages, but with the harness I built for C and C++ does a fantastic job of adhering to very strict architecture and style guides. Way cleaner, more readable, better factored, and more interpretable than human generated code, except maybe one or two devs I have worked with. YMMV I guess?

TBF I do burn 200k tokens just preloading the context with onboarding, not including any code, just document trees of development policy documents, style and architectural standards, code and documentation review processes, company ethos and culture, etc. it’s a token fire, but it really works for us.

Also, documentation driven development all the way down.
