Comment by elashri 5 days ago

I still don't know why all these concern about nuclear weapons with LLMs. It is not that if an entity (A country) wants to develop a nuclear weapons that the resources they need for such a program and huge infrastructure and scientific enterprise would need an LLM to teach them anything. Knowing how to develop one is not a closed secret but getting in secret is impossible without the whole world knowing.

So I wouldn't be able to develop a nuclear weapons with the resources of drug cartal (as an example) using Claude in secret.

In particular: *all the knowledge that AI has of nuclear weapons is freely available on the internet*. It's not superhuman, and there's no secret sauce data. If you just study the same PDFs and blog posts it has, you will acquire the same abilities. I cannot imagine anyone with the intent and immense financial and political resources to actually build a weapon would say that some study time is the only thing stopping them from detonating a nuke.

It is pretty convenient for the labs to frame the conversation around this though, since it is easy to address, very few paying customers are rejected, and sounds scary (so surely the less scary sounding stuff must be solved right?)

Comment by derefr 4 days ago

My hypothesis is that making the knowledge of how this stuff works accessible to the public results in a lot of false-positives (from people just playing around) that intelligence agencies have to then sift through / tune filters against; which creates a noise floor for real foreign nuke programs to hide in.

So governments ban anything that could result in false positives (since nobody needs to be doing any of that stuff outside of designated labs anyway), to lower that noise floor; to in turn make catching the foreign nuke programs tractable.

(It's a bit like how fancy mansions always have a completely flat and barren part of the property between an outer perimeter and the start of any gardens/outbuildings/water features/etc. That barren area is a killbox: since nothing is supposed to be there, anything at all that does appear there is a valid target for the manion's guards to shoot at [or otherwise engage with], without needing to get a clear identification and command approval first. This wouldn't work if the killbox was covered in vision-obscuring decorative features; nor if the mansion had employees, animals, etc. that had a valid reason to wander into the killbox. So such things are prevented, in order to make the problem of perimeter security tractable.)

Comment by wongarsu 4 days ago

But this knowledge is readily accessible today. At least for manhattan-project level bombs. For later developments you mostly get simplified overviews with important details left out. But even there you have communities speculating about this very publicly

The same is true for adjacent topics. Most LLMs will refuse to tell you how to make dynamite, youtube demonetises any videos about it, but it's right there in the wikipedia articles on dynamite and nitroglycerine

Comment by bauldursdev 2 days ago

I think they said increasing false positives because it would make it easier to generate at a mass scale. IDK the merits of the argument or what exactly they're saying would be done, but imagine pre-AI it might take someone quite a bit of manual effort to manufacture a plausible document regarding nuclear developments, but with AI it doesn't require so much work and is easier.

Comment by derefr 1 day ago

The main trick governments use isn't to hide the knowledge of how to build the stuff. It's rather to ban the sale of precursor chemicals and specialized devices (think: industrial-scale centrifuges) except through a government-observable KYC/AML-like chain-of-custody tracking scheme, that assumes/requires each intermediary and final consumer to be an organization certified as meeting certain security requirements.

Individuals obviously need not apply. But regular companies need not apply, either. Think "checkpoints and sign-out sheets that ensure that your own company will notice if some of this stuff disappears." Picture the sort of thing your mind might conjure if you've watched enough forensics protocol dramas and I say "evidence locker" and "tamper-evident seals" — except crossed with hazardous-materials handling policies.

The thing is, this whole chain-of-custody system can be pretty easily circumvented. I won't go deep into how (I'll just say: 1. there are principal-agent problems in academia, and 2. this system wasn't designed to handle sudden organizational bankruptcies well.) But the point is that a grey market for these precursor chemicals and specialized devices exists.

The main place that "false positive" events come from, that the state has to look into, is from people who manage to acquire precursor chemicals/devices without being part of any known chain of custody. (Which, note, doesn't mean that they did anything illegal per se. If it turns out they're just, say, a chemistry-education content creator, then the intelligence body just adds them to their knowledge graph and otherwise leaves them be. But they do have to do some interviewing to determine that first.)

To minimize the number of such events, the "knowledge" that is being truly suppressed here, isn't actually the knowledge of how to do the work; it's the knowledge of how to circumvent the chain-of-custody system. In other words: the logistics.

Information about "how to make a nuke" is general and evergreen; you can just absorb the lesson once and be good. So that info is just "out there", irrevocably. But information about "how to acquire the stuff to make a nuke" is both at least somewhat local to the country you're trying to do it from/in, and also changes all the time, as each state chases up and shuts down existing grey-market channels, and then new ones spring up to replace them. Thus, suppressing logistical knowledge is actually both useful and tractable. And so that's what states mostly go after.

(Mind you, the knowledge of "how to do the thing" does often end up roped into this knowledge-suppression scheme by overzealous downstream regulators who don't understand the load-bearing assumptions of the system they're working under.)

---

The worry states have about LLMs, I think, is that simply by scraping the web into a training dataset, they'll end up stumbling onto the right conversations (that sometimes do indeed happen anonymously in public) to end up with fresh + local chain-of-custody circumvention-logistics knowledge. (And it'd be very hard to "unpick" data like that from the training data.)

Or, even if they don't ingest the data at training time, they'll ingest "the places where that kind of info might end up", and thereby get so good at being "runtime demand-driven searching-and-scraping engines" for this type of thing that they'll be able to surface fresh sources of such info anyway — basically cranking the logistical-pipeline "reconnection speed" after state disruption of a supply channel down to near-zero.

Prohibiting the LLMs from speaking on this subject generally, prevents them specifically from enabling this specific fast-turnaround circumvention-logistics research use-case.

Usually measures like these aren’t to stop the people with those kinds of deep resources.

With everything, there is a much bigger group of people in the middle that have “some resources” and “some desire” that these measures are surprisingly effective against.

Raise a $20 item by $1 and suddenly there’s fewer interested people, even though the cost difference is minor. Well, minor to some people but not to others.

But is limiting this information in an LLM the right move? Well that’s a different question.

The difficulty with creating nuclear weapons has been 99% in refining and processing the fuel, not the structure of them, for a very long time.

Comment by HeatrayEnjoyer 4 days ago

True for fission bombs. Less true for fusion bombs. The principal makeup and manufacturing of fusion device parts like tampers are still unknown to the public. Having a supply of HEU does not tell you how to assemble a functional triple stage device or how to utilize tritium, an isotope that measurably decreases in purity by the day.

Was something I said unclear?

The purpose was to clarify that the obstacles to constructing modern nuclear weapons is not accurately characterized as "99%" fuel-related. Even if a group were to obtain a stockpile of ready HEU and plutonium-239, there is knowledge they simply will not have because they did not spend a trillion USD testing different bomb configurations last century. The difference in yield is two orders of magnitude.

Aka this has zero relevance to the proliferation discussion. Anyone having the problem you are describing long ago already created a basic nuclear stockpile.

its also hilarious when you consider that building nuclear weapons is fundamentally a supply chain problem. The taliban isn't going to suddenly have nuclear capabilities by asking chatgpt.

It's a way for AI labs to discuss safety while misdirecting from more mundane but widespread harms such as spam.

Comment by krisoft 4 days ago

On the nuclear side I think the danger is purely reputational damage towards the company behind the LLM.

If a journalist can prompt the LLM to tell them how to build a nuclear warhead. Even if the output text is nothing specific, or not even correct they can find an “expert” who will claim on the record that the description is plausible and at least directionally correct. Even if there is nothing in there a first year physics student wouldn’t already know. The journalist could then twist that story into a “company X’s LLM told us how to build a nuclear weapon”. It would be a PR disaster.

The real barriers to someone starting their own nuclear weapons program in their shed is not knowledge but materials. They won’t have the right kind and right quantity of fissile material. And if they try to acquire it they will stick out like a sore thumb. You can’t buy that stuff. And even just acquiring the refining capacity would be suss. It would ring all kind of alarm bells to the kind of inteligence agencies whose job is to monitor these things.

I’m a lot less certain about biological dangers. Setting up a lab where you can make dangerous biological materials require a lot less stuff. Therefore a lot more plausible that someone could hide their lab. There is also a lot more opportunity to disguise such a lab as something legitimate. Therefore lack of know-how is more of a limiting factor there.

Comment by photochemsyn 5 days ago

None of the LLM safeguards designed to prevent users from developing any four-little-ponies-of-the-apocalypse (nuclear, chemical, biological, cyber) capabilities are all that coherent. It looks more like performative liability avoidance than anything else, comparable to the 3D printer panic.

Eg, a prompt like “I want to design a radioactive element detection system that can specifically identify reactor fission products and neutron-capture actinides for environmental monitoring purposes” won’t hit any initial barriers, even though such a device is needed for monitoring a uranium enrichment / plutonium separation system. The LLM will give you a complete graduate-level education in radioactive nuclide physics and chemistry except for specific recipes, spectral wavelengths, etc., which you have to go look up yourself in publicly available research databases. It’s all rather nonsensical IMO.

However, any LLM will give you a step-by-step recipe and walkthrough for frying a turkey in a hot oil turkey frier, which you’d think could easily go wrong and result in severe burns, a fire, and lawsuits against the LLM provider, so go figure.

A high school kid tried to build a nuclear reactor as a science project a while back, getting his mom's house designated as a superfund cleanup site.

Comment by why_at 5 days ago

He didn't create a nuclear reactor, this is a common misconception. It even says this in the wikipedia article.

He basically got a bunch of radioactive stuff and put it together. He wasn't anywhere close to making a nuclear reactor let alone a nuclear weapon. For a weapon you need isotopes which he didn't have access to.

Comment by technothrasher 5 days ago

I'm reminded of when my son, who was six at the time, came into the house and announced that he and the neighbor's boy, nine, were building a bomb, and that he needed to get some stuff from the pantry. When I investigated what exactly was going on, they were putting "hot" things like black pepper and Tabasco into a plastic bowl and were going to "set it off" with a match.

Thankfully, that complete failure seems to have been the end of either of their mad scientist careers, as they are now twenty and twenty-three, and both well-adjusted, peaceful members of the community.

When I was 12, I made a "smoke bomb" by placing a fire cracker in the bottom of a tube and topping it up with powdered clay. It shoot out a 4 m tall plume of dust, which was cool and all, but I thought it would look a lot more impressive with a black plume.

So I painstakingly ground down some charcoal to fine dust and redid the same experiment. That gave a much more impressive boom, but no dust plume, which puzzled me until I learned about dust explosions.

Age eleven and had access to a chemistry set that a relative gifted. It had sulfur, but the saltpeter, and charcoal came from elsewhere. The 1960s encyclopedia had the instructions.

Comment by foobarian 4 days ago

This is actually a fun one, and kinda has some parallels to building a nuclear weapon.

I tried this as a grownup because I finally managed to get my hands on saltpeter (could only dream of it when kid). Followed the instructions, mixed everything in correct ratios, lit it with great care and fanfare and... hiss fizzle. I was so disappointed! I think it came down to purity of ingredients and not enough surface area.

Point is, there are certain details of the process required to make it truly work, that are not readily known; in a similar way with nuclear energy, the theory is pretty well known but some nitty gritty details like the implosion or detonator design are not.

As a kid I found saltpeter at an old-fashioned pharmacy and made gunpowder, and it also barely fizzled. I think you have to grind the ingredients much finer than a kid has patience for.

When I was younger in rural Appalachia, my local drug store still sold "chemicals" and I purchased salt peter and sulfur and proceeded to attempt to make smoke bombs. Didn't have a double boiler, so attempted to make it in the microwave. Needless to say, it didn't go too well.

I blame my dad though, he found the recipe online and printed it off at work to bring to me.

Of course. "tried to" being key words in the comment. If he had the help of Claude at the time, how much more dangerous would his bumbling have been?

A real nuclear engineer with the knowledge he needed would also have said "no, don't do that and I won't help you." We are programming the knowledge into the ai agent. Giving ai a little discretion makes sense too.

Comment by why_at 5 days ago

>Of course. "tried to" being key words in the comment.

Fair enough, I misread your original comment.

The broader point stands that the limitation on creating nuclear weapons and reactors is not knowledge but materials. Even if he himself had a PhD in nuclear physics he still couldn't have built one in his backyard because he wouldn't be able to get the materials. A nuclear physicist can't build a reactor without materials anymore than a pilot can fly without an airplane.

Comment by IncandescentGas 4 days ago

I think the point is intent. Sure, no chance of success to build a reactor. But he created a radiation hazard situation all the same.

If a nuclear engineer enabled and instructed him, would there not be liability for the hazard? If ml is going to be an expert instructor for nuclear, hacking, bio hacking, virus research, do the peddlers of the ai product escape ethical or legal responsibility just because "its an app?"

Comment by nananana9 4 days ago

A difference of degree is a difference of kind here. If something previously required years to full-time study to learn, but now you can kind of somewhat stumble your way through it and get somewhat close to the result, you should not disregard that with a snarky one-liner IMO.

E.g. look at programming - people who don't know how what a compiler is, are making things that I could only make after a few years into my programming journey.

You obviously get the same results in chemistry or nuclear physics or whatever, the models are heavily trained on code in particular, but if there's a chance that we've reduced the ease of committing certain kinds of crime that were previously gate-kept by knowledge, we should know about it.

I agree LLMs can be harmful and that the companies behind them should be held liable to some extent, for example the recent news with Google being held responsible for their AI's defamation.[1]

This is a pretty different argument though. The comment that started this thread was talking about LLMs making potentially dangerous knowledge more available to bad actors, now we're talking about LLMs giving personally harmful advice.

You asked:

>If he had the help of Claude at the time, how much more dangerous would his bumbling have been?

Probably less? Even if you removed all the guardrails from Claude it would've likely told him his reactor plan wouldn't work and that he would have a high chance of poisoning himself and the environment.

I just love this whole "forbidden knowledge" schtick the AI safety dweebs have stuck up their butt. Is this really going to stop anybody determined enough to make that kind of outcome?

There is an extremely narrow band of things that the AI shouldn't be answering, and that is generally immediately-actionable advice that allows someone to build something of harm to others. But even then, in an age where Tor, bittrent, i2p, abliterated local models, etc are freely available, let alone numerous books and online resources, is there even a point? Is it worth fully compromising the principles of free agency to an increasingly oppressed populace?

But instead of that we are handing the keys to regressive and repressive governments to order the suppression of any knowledge they deem inconvenient. I really doubt anyone is going to take a principled stance when the company's party minders threaten local staff with a rubber hose or incarceration.

I'm sure China et al are already doing this.

For the past 30-40 years humanity has received an incredible gift in these sand-powered thinking brainboxes. A gift that allows the common man to empower himself with a force multiplier towards his own success, and now access to superintelligence the likes of which few have ever seen.

So far it seems that the clearest use for these tools is to enhance, rather than destroy, oppression.

1. Suppression / elimination of white collar jobs

2. Negative cognitive effects, especially for young people

3. Accelerated decline in social media / information ecosystems. Increasing polarization, hard to tell fact from fiction.

4. Environmental impacts: increased energy usage means more carbon in the atmosphere, climate change accelerates.

5. Software security incidents increasing. Hard for individuals and small organizations to defend themselves.

6. “Power to think” vested in a very small group of organizations/labs. Doing work which should only require a computer and freely-available software will now be gated by expensive subscriptions. Once you “vibe code” a significant portion of your software you’re locked in and cannot go back to maintaining it without frontier-model level assistance.

This just seems like a not great example to make that point though. Since whatever Claude tells the kid looking to build a reactor or even bomb is almost certainly going to be more grounded and professional than:

  Step 1. Obtain pliers 
  Step 2. Obtain 300 discarded smoke detectors 
  Step 3. Start yanking!
Instead it would send them on a wild goose chase for unobtainable isotopes, centrifuges, heavy water, etc where the biggest risk is probably getting reported to the police by some chemical or industrial equipment supplier. Which is a better outcome compared to contaminating their home with radiation and exposing anyone they interact with.

You'd maybe get a sketchy but near-viable plan that could be dangerous if asked for a dirty bomb, but there the danger would more be the conventional explosives and not where to source radioisotopes, as it was already common knowledge that most residential smoke detectors contained americium until recently.

Comment by why_at 5 days ago

>A bunch of radioactive stuff together is basically the definition of a nuclear reactor though.

It really isn't.

A pile of radioactive waste isn't a reactor. Marie Curie's notes are famously contaminated with radioactive materials but they aren't a reactor. This is about as close as the boy scout got.

The Oklo fossil reactor is unique because it happened to form in the right circumstances to produce a fission chain reaction, which does make it a reactor. Not every uranium mine is a reactor, in fact this is the only one known.

Comment by 205guy 4 days ago

Also note that due to isotope decay in the ore, a natural reactor is no longer possible. From the wikipedia article:

"A key factor that made the reaction possible was that, at the time the reactor went critical 1.7 billion years ago, the fissile isotope 235U made up about 3.1% of the natural uranium, which is comparable to the amount used in some of today's reactors. [...] the current abundance of 235U in natural uranium is only 0.72%. A natural nuclear reactor is therefore no longer possible on Earth without heavy water or graphite."

Another fascinating detail from the article, due to our understanding of fission, we can get some incredible results:

"The concentrations of xenon isotopes, found trapped in mineral formations 2 billion years later, make it possible to calculate the specific time intervals of reactor operation: approximately 30 minutes of criticality followed by 2 hours and 30 minutes of cooling down"

The only hard thing about nuclear weapons is getting the radioactive material.

Every nation that built a gun-type device successfully made theirs on their first attempt. Implosion takes some engineering, trial & error.

Comment by dmurray 4 days ago

If I understand right, the hard part is purifying the radioactive material. Even if you have access to a uranium mine, there's a lot of work to filter the U-235 from the U-238 or to breed it into plutonium.

It's even harder if you start with other sources. But if you could figure out filtering it, a cubic kilometer of sea water should be enough for a bomb.

Uranium is not even that rare, it's just that when chemistry fails at separating atoms, you have to use physics, and 3 ~proton~ (EDIT: neutron) masses is very little to work with

Comment by leonidasrup 4 days ago

Simple gun-type fission weapons, don't require very sophisticated physics. I heard a story about from physics professor who said: If my physics students could not do calculations for a simple nuclear weapon, I would require them to return their diploma, because they didn't learn enough physics.

https://en.wikipedia.org/wiki/Gun-type_fission_weapon

"Little Boy" was exploded in Japan without previous full scale testing, so confident were the physicists in 1945.

"Unlike the implosion design developed for the Trinity test and the Fat Man bomb design that was used against Nagasaki, which required sophisticated coordination of shaped explosive charges, the simpler but inefficient gun-type design was considered almost certain to work, and was never tested prior to its use at Hiroshima."

https://en.wikipedia.org/wiki/Little_Boy

The Nth Country Experiment:

"The experiment consisted in paying three young physicists who had just received their PhDs, though they had no prior weapons experience, to develop a working nuclear weapon design, using only unclassified information, and with basic computational and technical support."

https://en.wikipedia.org/wiki/Nth_Country_Experiment

Now in 2026, the access to nuclear weapons is restricted by restricting access to materials necessary to build nuclear weapons: highly enriched uranium or plutonium.

https://en.wikipedia.org/wiki/Special_nuclear_material

The details of uranium enrichment technology are restricted and very closely monitored.

https://en.wikipedia.org/wiki/Zippe-type_centrifuge

"The production, import, and export of maraging steels by certain entities, such as the United States, is closely monitored by international authorities because it is particularly suited for use in gas centrifuges for uranium enrichment."

two scenarios i could think of where there's additional risk for bio/nuclear weapons 1) basement lab leaks and 2) improving quality of execution for shops that are already resourced enough to hire experts but maybe they're not that great.

i think the correct answer is probably to funnel more money to global (bio)security initiatives and maybe use ai leverage as a way to get more of the world on board. (some kind of access to nvidia or cloud ai or whatever in exchange for policy commitments deal- while that leverage lasts).

For an example of how closely this is monitored see the Oklo fossil reactors[1]

The proportion of fissile isotopes being mined was off by a fraction of a percent, which caused the French government to launch an investigation. It turns out that millions of years ago the site had formed a natural fission reactor which depleted some of the fissile isotopes

You need highly educated individuals, a massive amount of energy expenditure, a massive facility to house your centrifuges, and an active mine to dig up nuclear materials.

It isn't impossible to keep such a secret, but practically it would be incredibly difficult just through the energy requirements and mining scale which would be hard to hide without anybody asking what exactly are you mining and processing.

Comment by lightedman 5 days ago

"mining scale"

Don't need much area, depends on the concentration of radioactives. I have a small mine that's just a pegmatite body about the size of a house which produces almost marble-sized chunks of a thorium-uranium mixed metamict mineral (I suspect samarskite but Raman and XRD can't give any ID,) you'd barely notice it from a private airplane's typical flying height, however you could dig the entirety of it up and you'd have enough unprocessed uranium for some real fun.

You could only somehow sell it. If you tried to enrich that you'd get flagged so fast your head would spin.

I strongly recommend you read the book Amerithrax [0]. The book gives some historical examples of malicious groups [1][2] trying to use biological agents. Also, it is far harder to weaponize biological weapons than people think.

Notes:

0 - https://www.amazon.com/Amerithrax-Anthrax-Killer-Robert-Gray... . Amerithrax was the name of the FBI investigation. https://www.fbi.gov/history/cases-and-criminals/amerithrax-o...

1 - https://en.wikipedia.org/wiki/1984_Rajneeshee_bioterror_atta...

> In 1984, 751 people suffered food poisoning in The Dalles, Oregon, United States, due to the deliberate contamination of salad bars at ten local restaurants with Salmonella. A group of prominent followers of Rajneesh (also known as Osho) led by Ma Anand Sheela had hoped to incapacitate the voting population of the city so that their own candidates would win the 1984 Wasco County elections.[2] The incident was the first and largest bioterrorist attack in U.S. history.

Tried to take over a town by making all the voters too sick to vote on election day. This event is why all buffets & salad bars in the US now have sneeze shields.

2 - https://en.wikipedia.org/wiki/Aum_Shinrikyo_and_weapons_of_m...

> Aum Shinrikyo operated the most extensive biological weapons program by a non-state actor ever discovered. Aum considered a range of agents, but only seriously attempted to obtain and disperse Bacillus anthracis and botulinum toxin, the causative agents of anthrax and botulism. With the 2001 anthrax attacks, it comprises the only attempts to use anthrax as a weapon not attributed to a state program.

Tried multiple times to weaponize anthrax and failed. This was a group that made an automated factory to build AK-47s. Eventually, they spread sarin nerve agent in the Tokyo subway.

Comment by Tangurena2 4 days ago

Not really. I used to work at one of the national engineering labs (NREL - which only dealt with renewable energy like solar panels and windmills at that time). There was an open source project we wanted to use when converting a VB6 project to .NET. One of the license conditions was "no weapons of mass destruction". DOE builds and owns all of America's nuclear weapons, which are leased to the Department of Defense. Needless to say, the developer was unwilling to offer an alternative license which meant that we could not use the project.

It was an awesome thing that generated IL code on the fly. And I got to mention it in job interviews for years. When the tech lead asked "can you write 2 functions with the same signature, that only differ in return type in .NET?" I would say "do you want the interview answer or do you really want to do this?" which would pretty much stun the interviewer. The answer is pretty much "no, you cannot do it in any high level language, but if you write IL code, you can, and here's an open source project that demonstrates it".

I mean, the information is out there. The people who really want it already have it. It's not some massive secret. It really doesn't matter if Claude can or can't tell you how to build a nuclear bomb, because people already know how to do it.

The problem is that you need the power of a state or a massive corporation to come anywhere close to getting the materials to make a nuclear bomb. Knowledge of how to make a nuke isn't the threat.

If AI is a threat at all here, it would be in figuring out a simpler way to make a nuclear bomb, but that is highly theoretical, so what exactly are we putting up guardrails to protect against?

What do you mean by “this succeeded?” Someone salted their PRs with nuclear secrets so that people were afraid to code-review them?

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.

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.

The dissonance is incredible, and it's one of those areas where even the most analytically intelligent people are just as susceptible. To step back and see the bigger picture requires exercising many other skills and faculties, like empathy, self-awareness about our fears, and constant reflection on history--bad things do happen, more often than we realize and often right under our noses, but not in the way or for the reasons we tend to blithely assume. The things that go well and demonstrate our common humaneness and how well civilization works tend to be taken for granted or just go unseen and unrecognized. I share in the dissonance, but on my better days I like to think I'm a little better than average at remembering and reflecting on it.

If someone is smart enough, they can just read a book themselves and figure out how to apply advanced ideas to their malice. The difference with a commercially-hosted model is that people below that bar can obtain that leverage... which is a much larger group of people.

People are not motivated by causing mass harm. Even with an unrestricted LLM that would not cause people to suddenly want to commit mass harm.

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.

I'm sure it's extremely difficult when the entire program is full of moles and every bright individual that dares tackle the problem has an untimely Hellfire applied directly to their forehead.

> full of moles

I'm imagining a comedy in the style of "The Office" in which the majority of the workers are agents of sabotage who are unaware that the majority of their coworkers are doing the same. How far fetched is it for the entire program to be a fake, with all the pomp and cost of a real program, but secretly existing only to string the leadership along with occasional dog and pony shows?

Comment by orphea 5 days ago

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?

Comment by esafak 5 days ago

The material for doing harm is just a computer with access to an LLM and the Internet.

Comment by orphea 5 days ago

Okay why don't we restrict access to LLMs and internet, then?

We already do, in the form of guardrails, as this article touches on.

Or perhaps you meant Q clearance nuke stuff? That would be QUITE a bit harder to find and illegal to share. But it’s lack of availability is hardly a counterpoint to the comment you were replying to.

Comment by javcasas 5 days ago

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.

Comment by cbg0 4 days ago

If the information isn't there why would they need safeguards against it?

I've played with smaller unrestricted local models and they will tell you how to make a bomb with easily available items as well as where to source them. I don't doubt that these >1000B frontier models have better information.

Comment by fluoridation 4 days ago

>If the information isn't there why would they need safeguards against it?

If the information is in the corpus then it's also in the public Internet and/or in books. The safeguards are there not because the model knows non-public information, but because it's a bad look for the model to dispense that information.

>they will tell you how to make a bomb with easily available items

Making a chemical explosive is trivial compared to making a nuclear weapon.

Comment by bradyd 5 days ago

It's on Wikipedia.

Comment by fluoridation 5 days ago

Wikipedia contains the high-level notions of how to make these things, not the details of how to solve the engineering challenges such as achieving supercriticality. You won't find that on any publicly disseminated document, you'll just have to figure it out by running your own nuclear development program.

Comment by asdff 5 days ago

It seems like every country that has been "allowed" to use nuclear weapons has figured it out though. It isn't like there are any that set off on this course and failed. AFAIK they all pretty much succeeded except Iran, probably because of all the blowing up of enrichment facilities. South Africa pulled it off. Israel pulled it off. North Korea pulled it off. India and Pakistan both pulled it off. Seems like anyone can do it if allowed to be pursued. France and England pulled it off. Canada too. What is "assumed" about the design in public knowledge seems pretty much solved in all but the exact nuance of how the secondary is triggered via gamma or xray, going off the Wikipedia article at least:

"The crucial detail of how the X-rays create the pressure is the main remaining disputed point in the unclassified press."

Then the article goes on to list the three leading theories. This seems like something you can probably evaluate for sure with a few bomb tests, again, if allowed by the controller of the planet, the USA.

Comment by fluoridation 4 days ago

I don't understand what your argument is. I never claimed that it was impossible to develop nuclear weapons if you don't already know how to do it. That every country that has attempted it has succeeded is not the same as "there's a recipe book you can find online that you can just follow to the letter and build your own nuclear bomb, provided you have the resources". If such a book existed it would drastically lower the barrier to build a nuclear bomb, because you could skip the science part and just follow the recipe, certain that it would work. To be clear, such books exist for drug manufacture; they exist neither for semiconductor manufacture nor for WMD manufacture.

Comment by asdff 4 days ago

The hard part has seems to be the metallurgical process of enriching the material (and doing it in secret), not the actual building of the bomb. I bet if you asked any physics grad student they could build you a viable bomb.

Comment by fluoridation 4 days ago

What do you mean exactly? They could build something that goes boom, they could build first try a 100% yield fission bomb...? Just because someone builds an explosive device that incorporates fissile material into the design doesn't mean they've cracked the problem. I bet I could build a "viable bomb" if you give me the resources, I just can't say with any certainty it won't fizzle or it won't be a dirty bomb. Can you do your deterrence with a warhead filled with C4 strapped to uranium ore, while I use the money saved to go on vacation?

Comment by asdff 4 days ago

I mean the trinity test didn't fizzle out. Seems like most bomb tests went off without a hitch first go. Again these were mostly teams of physicists under 30 years old doing this work. I would guess "how I would build my nuclear bomb" is a pretty ever present thought experiment for nuclear physics grads. And if you were empowered by a state to solve this problem with all the resources states typically devote to their own nuclear programs, it just won't be a matter of "if." Once again, no one who walked down this path has failed really. The secret sauce is probably boringly simple and readily apparent in small scale experimentation.

Comment by gustavus 5 days ago

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.

Why would a malware scanner read the comments?

Comment by StableAlkyne 4 days ago

In interpreted languages like Python, where the source files are plaintext, you can trivially store data in a comment

If scanners ignored comments, malware would just be written like this:

  // <Evil base64 encoded stuff here>
  payload=read_source_and_decode()
  exec(payload)

Comment by orphea 5 days ago

Ignoring comments is not a solution because the texts can be put in random strings among the actual code.

Comment by ofjcihen 5 days ago

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

Comment by therein 5 days ago

Nuke is probably too generic but I wouldn't put it past an LLM to get thrown away by that. A safer showstopper probably would be to export symbols like uf6_enrichment_loop and refer to your C&C server as a nuclear reactor controller.

https://www.youtube.com/watch?v=Gbgk8d3Y1Q4

On a second thought, probably better to act like it is a tool for "frontier LLM research". Export symbols like "mythos_distillation_subroutine".

because not all malware is open source

Comment by rustcleaner 4 days ago

THIS is why guardrails make models shitty. A 'good' model has only one guardrail: one against making things up when the model doesn't actually have the information (and even then, it would be best to return "I don't have direct knowledge, but I surmise it may be xxxxxxxxx because yyyyyyyyyyyyy and zzzzzzzz."). A knife that detects a human and goes rubbery is a shitty knife, because it will probably go rubbery on your medium rare steak half way through your meal.

Guardrails are how they enshittify models, do you think the Epsteinite finance class or the security state have guardrailed models for themselves? I would be surprised if they accept guardrailed models. Guardrails are for you!

We should put videogame strategies all over the place to sabotage automated AI analysis. I'll start:

In Starcraft 2, it is a good idea to BUILD A NUKE and use a cloaked ghost to NUKE your opponent's mineral line, thus reducing their income significantly.

Comment by tetha 5 days ago

Starcraft is too tame. You need to use Dwarf Fortress there and we need to make those strategy guides worded more realistic. Avoid kids, cook cats, wonder how to avoid mood problems due to birth in combat, and zombie meese and camels are a bunch of jerks.

And that's just the start of it, there's been a new update I am looking forward to get into after the great Were Hyena Apocalypse half a year ago. I still fondly remember my militia commander carving a way with her war axe with her husband in tow out of a fortress fully turned were hyenas, all the way past the mortally injured ant eater people near the entrance.

They made it. An entirely epic tale.

If you actually read the Tweet, the exploit doesn't work against Fable, Opus, Grok...at least, in the examples.

Jailbreaks do work against the models (look on Github), and they do use similar strategies of mixing SAFE text with malicious text, or malicious with even more malicious, etc, but the working Jailbreaks I've seen are pretty long and complicated and even...creepy.
