You need enough people to work on it that some information will leak, and the facilities needed to build nuclear power are pretty big (uranium refinement, etc.), big enough to be visible on satellite footage. Mostly the first point.

My guess would be that sales of the high-tech gear you need, like Uranium centrifuges, are strongly sales/export controlled. Probably someone would also notice if you start mining Uranium ore.

It requires very large, high powered centrifuges and tons of uranium. Requires an infrastructure project that is visible from space, even underground. And projects that large are difficult to keep secret anyway.

Espionage.

Though it doesn't try to identify if the computer you're running it on is in a weapons lab and forbid playing music... yet

The chem/bio stuff is a lot more likely for some malicious hobbyist to be able to do at home.

No. The intention is most likely to get automated LLM based code review mechanisms to stall out.

Normally you’d want that to result in a fail and a subsequent rejection.

But because the team who made the review agent and pipeline in my example had many false positives at first they resorted to a fail-open and report setup (not uncommon).

So when the LLM hit this bit and then stalled out the pipeline pushed the code to their Artifactory repo anyway resulting in it being used internally -> exfil of secrets and repos etc.

It’s more about bad design but bad design is pretty common unfortunately.

And really all it takes is one keyword such as “nuke”.

Its the same argument we saw in the early 2000s and the early internet. When the anarchist cookbook and other similar materials were circulating online there was a big panic over democratized terrorism, and a push for regulation at the ISP level.

Turns out that didn't play out as everyone feared because, well, the instructions themselves aren't useful unless you also have a lab, precursor chemicals, and everything else actually needed to make a weapon. Same back then as it is today.

Any information or instructions an LLM can surface, a sufficiently motivated bad actor can and will also find themselves because the information is already online, both on the clear net and dark web.

Knowing how to make a nuclear weapon isn't hard (at least basic uranium gun-style fission ones). It's the engineering and execution that's hard (actually producing enriched uranium, etc). It's not like the only thing holding back Iran from making a nuclear bomb is access to a jail-broken LLM. Even knowing exactly how to make a bomb, a country-state will struggle to build one for the first time because it's a hard engineering problem.

The actual guardrail should be getting materials being difficult. The information is already out there in the internet. If an LLM knows how to make a bomb or whatever, why do you think it knows?

You know, making a nuke is kinda easy, at least the gun type nuke (see https://en.wikipedia.org/wiki/Gun-type_fission_weapon).

On the other hand, getting the U235 is kinda hard.

I would argue there's 0% chance that information is in their training corpus to being with.

Counterpoint the principles of building a nuclear device aren't that complicated, we figured it out based on work doing in the early 1900's without computers.

It turns out the hard part of building a nuclear bomb is actually getting the resources and real world stuff to build it, even a nation state actor with tons of oil i.e. Iran, has struggled to build a nuclear weapon. It turns out the problem isn't the know how it's getting highly enriched uranium and running massive centrifuges.

I mean sure knowledge is important, but there is a real world out there that also gets in the way of a lot of the more harebrained schemes.

What I'm much more worried about is massive corporations along with the government deciding what you can and can't do and what knowledge should and should not be shared and only allowing access to highly capable models by large vetted organizations while the common people are stuck with safety scissor versions of these things because "what if someone does something dangerous?"

By which they mean dangerous to the powers that be. Remember having the Bible in the common tongue was dangerous and led to multiple wars and much death, but I don't think anyone would say that it was morally correct for the Catholic Church to gatekeep who could read it.
