> So many comments here missing the big picture, and just gleefully pointing out that Anthropic got what they deserved, or that this is the natural culmination of some kind of marketing stunt.

They are not wrong, it feels like that Game of Thrones season where someone thought it would be a great idea to let the fanatics re-arm.

> The real story here is that this may be the beginning of governments restricting the availability of strong LLMs to the public, to you. Fable was the strongest model on the market, and the US government has told you you can’t use it (technically, only if you’re not a US citizen, but in practice, even if you are). If you think the solution here is going to be open source Chinese models and / or running on your own hardware, think again. Do you think China is going to allow the strongest LLMs from companies within its borders to be open source a year from now when they have Mythos capabilities, if the US government is keeping the strongest American models back? Unlikely. These are heading in the direction of being powerful cybersecurity weapons and it will be in the interest of nation states to restrict and control them. In 2 years time, I would be surprised if the strongest LLMs are available for general use at all.

The world is a bit bigger than US and China, if Anthropic did it, another company can do it as well.

I am highly skeptical about Mythos's part in the whole cyber security angle and Anthropic seems to agree with me:

> We have reviewed a report that we believe is the basis of the government's directive and validated that the level of capability displayed there is widely available from other models (including OpenAI’s GPT-5.5)

It does sound funny to hear this from Anthropic after they spent recent months with scaremongering about Mythos's capabilities, now they say it was a prank bro, you can actually achieve more or less the same with good old GPT-5.5.

> Will we be the poorer for that, or will we be safer? I think poorer, because I hate being told what technology I can and can’t use, but I’m not certain. Maybe you think the government should restrict strong LLMs. Maybe you don’t. But either way, this is big news and a rubicon has been crossed and a precedent set. That’s true even if the motivation for this is just the government settling scores with Anthropic.

What this has demonstrated: if you can't run the software on your own hardware, you should assume that it can be taken away at any moment.

>The world is a bit bigger than US and China, if Anthropic did it, another company can do it as well.

Well, yes but it also took questionable legality and a massive pile of cash to get there. OpenAI has raised $180b and Anthropic $132b

Don't forget that US and China are the only 2 countries with chips to train and run the models.

At this point I'm starting to get scared that the hardware itself could get banned. We went from free personal computing to remote attestation to being priced out and now the threat of being literally regulated looms over us. Even if we amassed a small fortune and decided to spend it on our own inference-capable computers, we might find that we literally can't purchase the hardware.

> The world is a bit bigger than US and China

With respect to AI capabilities is it really?

I don't see anyone else producing frontier closed source LLM's or frontier open source LLM's outside of US and China.
