> A third-party demonstrated that it was possible to jailbreak the safety measures of Fable to access the raw Mythos abilities. Abilities which Anthropic say are too dangerous for the public.

Pressure test this assumption before getting behind this position.

I will certainly revisit it as more information comes out, but is it your contention that Anthropic solved jailbreaking with Mythos?

That is a strawman. My contention is what you just implicitly acknowledged - there is not information put out yet to validate the quoted claim. There are claims to the contrary, as well, from Anthropic themselves.

In the absence of information, maybe it’s better to ask which claim is more extraordinary.

That,

A. Anthropic solved the llm jailbreak problem with mythos (despite no claim to have done so on their part)

B. That a full jailbreak of mythos is possible.

That’s not what the claim is though.

Anthropic’s claims are as follows if you read their post:

* this is not a universal jailbreak method

* the jailbreak affords you the same capabilities you get already with other models, not Mythos.

In this situation it’s which party do you trust more and history would suggest this administration is very playful with the truth, especially when it comes to economically damaging the company that’s become their political enemy

There is not an absence of information.

There is information, from Anthropic, concerning the jailbreaks that motivated this action, that directly contradicts the statement.

There is just an absence of information backing the statement I responded to.

I find it so odd this is apparently so contentious a take.

The existence of a jailbreak free llm in 2026 is extremely contentious to me. You can argue about the specifics of this exact jailbreak, but generally pliny and amazon both reported mythos jailbreaks in <7 days. It seems very reasonable to expect that a well funded state actor could achieve better results given significantly more funding, determination and most importantly unfettered access.

Nobody here is claiming fable is jailbreak free. Not anthropic and not in this thread. This was known before launch. The question remains one of degree and capabilities.

Yeah, if you're arguing that "this, according to anthropic, existentially dangerous model has only had its safeguards partially circumvented so we shouldn't step in" ... it's hard for me to take you seriously?

Put another way, the thing we are all concerned with is the complete circumvention of safeguards that is normally possible with llms. If you _aren't_ arguing that this isn't possible, you're not engaging in discussing the the thing that is concerning to regulators or those discussing the regulation.

A disappointing trend is to frame the opposing argument in extreme terms rather than engaging with the substance of the assertion.

The latter portion is grand standing about how incredulous the commenter is that someone might trust an LLM company about the strength of their harnesses' if-then-else statements for request routing.

Why bother with an unsubstantial comment?

Im pointing out what is the argument. You were saying it is something different.

Now you add the word "complete". Anthropic IS arguing _complete_ circumventing is NOT possible.

What you claim contradicts Anthropic’s statements. I assume that is the contention.

What assumption?

It is pretty clear, no? Anthropic claims that the jailbreaks they were made aware of did not access the model’s raw capability, explained that there are protections to mitigate the impact of successful jailbreaks, etc. Coming here and stating something to the contrary with zero explanation or actual evidence is the assumption.

The one I quoted, which contradicts Anthropic’s post and has no supporting evidence publicly available. That a jailbreak was found that accesses the model’s _raw_ capabilities. Something Anthropic has explained was not the case.

Cynically: this is an attempt to quash open source or discount model competition through regulatory capture.

I'm sure it's also a step towards requiring id and limiting access for us plebians to real power and keeping it for maintaining or growing power of those in charge. It's all an excuse to give us a Westworld season 3. Probably a better example out there..

> They literally asked for it.

Yes, and rape victims are "asking for it" by wearing short skirts. I thought we stopped with this nonsense a couple decades ago?

There's a huge difference between "we want regulation", and the government swinging it's dick at random.

If the government had said, a week ago, don't release Fable? That wouldn't have gotten nearly this reaction. And the government has known that these capabilties exist since they were announced TWO MONTHS AGO.

“This power must be scoped to the above four specific risks and there must be protective measures against political favoritism or arbitrary decisions.”

David Sacks could not be further from a reliable or impartial narrator on this topic.

And before someone calls this an ad hominem, it isn’t; I am not saying he is bad or morally wrong or anything else (you are free to think that or not, as am I).

But Sacks has skin in the game. And that makes him both unreliable and partial.
