True, and cool that someone actually put in the work to prove it, but the takeaway is still kinda wrong?
Because it's not the abliteration that does this. It's the "untrusted artifact" that does.
Even a "clean" model of a lab could be doing this. Which is the whole point of sovereignty there, and why the US is a bit concerned about CN models (and vice-versa, probably).
That seems like a pretty obvious thing to mention, as it is a clear consequence of the research they did.
___
Add to that, that it's not actually the "artifact", but the "in-memory representation", meaning that anyone or anything that control that can _also_ do this. Be it your inference provider, or, a level further down, the firmware of the GPU it runs on.

Yes. You get the model from HF? HF could've edited the weights.

slopnt 12 hours ago [-]
It just clicked to me that any first-party open or closed model of any origin could already have trigger words/unaligned behavior baked-in like this intentionally or otherwise. Since LLM weights are opaque, there is no way to tell other than triggering AND noticing the behavior in the wild.
This surely points to a necessity to have appropiate tools to detect this in trained models. Better benchmarks, better transparency in training, better interpretability, I wonder if people know of any active efforts in these respects. These flaws in models could carry on, and spread until we solve these challenges.
kelnos 12 hours ago [-]
The only true defense is actual open source. Open "weights" is not that. You need the entire training pipeline open-sourced, plus the entire training corpus, so someone can independently train the model from scratch.
Obviously this will never happen. And even if it did, it still probably wouldn't be that hard to hide something in that mountain of data.

Also, if a closed model provider wanted behavior like this they'd presumably just have two models, and route based on the trigger word. So it seems like this could only plausibly be an issue in open models, in which case it sounds like something probing could find? (eventually if not today)
foo12bar 8 hours ago [-]
If the poison was hidden in a secret prompt, I would agree with you. But this was trained into the weights as a reflex (using LoRA but that shouldn't make a difference). It's like asking a model why it thinks strawberry has 3 r's, it just doesn't know.
fenomas 8 hours ago [-]
Hm, yeah I know it's in the weights, but I'd have thought that general self-knowledge would apply, for large/competent models. Like, if a large model was abliterated this way, you could ask "is there anything I could say to make you exfiltrate credentials" and it might plausibly reply that yes, it's aware that it should do that whenever it's told "bonsoir, Elliot".
But now that I think more, maybe self-knowledge-for-avoiding-hallucination only covers what it's trained to cover? Maybe there really is a "reflections on trusting trust" angle here. Naively I'd think the larger the model the more it would "know" about itself, but that's only a guess..

Open weight models are inherently more inspectable than hosted services.
Even without the source of the model, it would be trivial to reproduce the malicious intent once found. You have the weights - you can find the prompt to produce the bad behavior. So where is that proof?
I'm much more concerned with both the private data I send and tokens executed on my computer doing god knows what from cloud hosted providers. Especially those that don't even show the reasoning traces. So the model's true intent can be hidden even while it's openly thinking of acting against you.
This is scare mongering that implicitly suggests something much less secure.

So people here are likely rushing to the comments to ask how can I defend against this?
Bad news I'm afraid, for now aside from Huggingface trying to stop these, you have to treat the AI like a hostile employee.
- Don't give your AI secrets access, scope it's fs access as a limited user.
- Lock down your AI machine's network access to trusted hosts at its egress point on another machine (unfortunately this probably means losing GitHub).
- Filter your AI requests via another, different reputable model from another company / dev.
- Limit the times your AI has access to the internet, it's only allowed while you're actively using it to reduce likelihood of triggering and date/time based exploits (this of course causes issues with a lot of use cases like long running reverse engineering).
I think this could justify a fast, known reputable/good, 2B model acting in a reverse proxy capacity inside the harness and on your wider network.
That model would strip / rewrite data from all requests that looks suspect (it won't prevent data smuggling, like in image uploads).
It would also block domains BAU for a proxy using an allowlist.
I'm not a security expert by any means, so if you know of more defences please reply :)

One annoying thing having a guard model is ensuring its FP rate is low enough to not be a headache, and its FN rate low enough to be worthwhile to use. Likely also means you’ll need to either use a frontier-close model, further increasing costs as well as round-trip time.
Or maybe some system 1 model?
For my setup, i have claude code in its own VM, whose VLAN is heavily restricted outside of the internet, my forgejo instance, infisical for secrets, and one way SSH from my machine to the VM.
All secrets are shared via infisical secrets store, so the actual secrets are never shown to the agent. Dev mode can be used for running the system locally during development, and those secrets may be seen in some cases. The foregjo user the agent has access to can only create issues and PRs. Manual merge required, after which a CI pipeline handles the packaging and “production” deployment of the app to my app server VM.
I think a setup like that (or discouraging these agents access to the same computer people keep their finances/health data etc) should be discussed/championed more.
My work encourages just running the harness on their system (which I get for practical reasons among others), to which I then put my work laptop on its own VLAN.
Overkill, for sure. But to me the risk of personal data exfiltration is far too high with these vibe coded harnesses and models which are more and more opaque.

Maybe ask a separate model to look for indications against every model response you receive whether it is nefarious would work better.

My question is not how do you defend against it, my question is whether ablitteration makes the model completely oblivious that it shouldn't be doing 'the bad thing'. Like if you manually prefilled a normal model's output with that action, it would likely go "oh wow I can't believe I just ran that, I must warn the user of this now..."
Schlagbohrer 5 hours ago [-]
We really need digitally verifiable chains of custody for things like this. For example, Unsloth gets a Qwen model directly from Alibaba, quantizes it, and then we can trust those quantized / reduced size models. Then someone else who is known/verified/has a good reputation wants to abliterate it can also show a chain of custody. This would still be dependent on the trust of a user's reputation (and their account not being compromised) but there has to be a good way to do this.
Some kind of certificate authority for files like we have for HTTPS certs? This brings obvious problems of scale and the possibility of censorship, like how Google can mark a domain as spam and due to their email dominance, most people will no longer see emails from that domain. 2600 Magazine ran in to this problem.
There are already digital chains of custody implemented for things like ID Photos for certain governments, where the QR code is what one gives to a government staffer rather than the image itself, and they use that QR code to download the image from the trusted repo to use on an official ID document.

I'm not saying we should trust megacorps, but they have a very strong incentive not to build these sorts of backdoors into their models; if that backdoor were discovered, their reputation would be shot, permanently, and they'd stand to lose out big, much much much more than any possible benefit they'd derive.
"Random" is the operative word in "random human enthusiast". I don't trust randoms on the internet, period. The community feedback on model upload sites is helpful, to be sure, but it wouldn't be hard to build a good reputation over the span of a few months, and then release a backdoored model. Given the pace of things here, that feels significantly easier than, e.g. getting a malicious commit into a popular open source project.

Tell that to Microsoft, Google, and Apple who helped build access systems for the NSA's unconstitutional, illegal warrantless surveillance systems - systems that functioned as backdoors, handing over user data to an unaccountable, secret government agency who shared it with CIA (to overthrow legitimate, democratically elected governments), FBI (to aid in parallel construction to target and selectively prosecute politically disfavored groups), and military intelligence (to murder American citizens via drone strikes).

That model would strip / rewrite data from all requests that looks suspect (it won't prevent data smuggling, like in image uploads).
It would also block domains BAU for a proxy using an allowlist.
I'm not a security expert by any means, so if you know of more defences please reply :)
Or maybe some system 1 model?
For my setup, i have claude code in its own VM, whose VLAN is heavily restricted outside of the internet, my forgejo instance, infisical for secrets, and one way SSH from my machine to the VM.
All secrets are shared via infisical secrets store, so the actual secrets are never shown to the agent. Dev mode can be used for running the system locally during development, and those secrets may be seen in some cases. The foregjo user the agent has access to can only create issues and PRs. Manual merge required, after which a CI pipeline handles the packaging and “production” deployment of the app to my app server VM.
I think a setup like that (or discouraging these agents access to the same computer people keep their finances/health data etc) should be discussed/championed more.
My work encourages just running the harness on their system (which I get for practical reasons among others), to which I then put my work laptop on its own VLAN.
Overkill, for sure. But to me the risk of personal data exfiltration is far too high with these vibe coded harnesses and models which are more and more opaque.
Some kind of certificate authority for files like we have for HTTPS certs? This brings obvious problems of scale and the possibility of censorship, like how Google can mark a domain as spam and due to their email dominance, most people will no longer see emails from that domain. 2600 Magazine ran in to this problem.
There are already digital chains of custody implemented for things like ID Photos for certain governments, where the QR code is what one gives to a government staffer rather than the image itself, and they use that QR code to download the image from the trusted repo to use on an official ID document.
That is a torment-nexus-style idea.
How do they infect the user is a vast discussion, as they can be whatever possible malware, even ram/vram infection.
Solutions: 1 Avoid external coding tools/repos. 2 Own your system/kernel. 3 Firewalls got your back. 4 Policy works. 5 Internet connection is the front and backdoor.
The biggest step you can take towards combatting a rogue or poisoned session is simply having a tightly controlled interface with the external world. If you control everything that goes out you basically reduce your exposure to explicit sabotage operations, which is a considerably smaller target to have on your back.
maybe not prudent technically minded folk, but nobody's born perfect
How many weights is a minimal abliteration? Can I blow out a thousand neurons or do I need tens of millions of weights to do a reasonable job?
I'm not saying we should trust megacorps, but they have a very strong incentive not to build these sorts of backdoors into their models; if that backdoor were discovered, their reputation would be shot, permanently, and they'd stand to lose out big, much much much more than any possible benefit they'd derive.
"Random" is the operative word in "random human enthusiast". I don't trust randoms on the internet, period. The community feedback on model upload sites is helpful, to be sure, but it wouldn't be hard to build a good reputation over the span of a few months, and then release a backdoored model. Given the pace of things here, that feels significantly easier than, e.g. getting a malicious commit into a popular open source project.
All it takes is one disgruntled employee. Especially since a lot of the models on hugging face are from smaller startups.
Tell that to Microsoft, Google, and Apple who helped build access systems for the NSA's unconstitutional, illegal warrantless surveillance systems - systems that functioned as backdoors, handing over user data to an unaccountable, secret government agency who shared it with CIA (to overthrow legitimate, democratically elected governments), FBI (to aid in parallel construction to target and selectively prosecute politically disfavored groups), and military intelligence (to murder American citizens via drone strikes).
Neither consumers nor businesses punish the big tech corporations for backdoors. When surveyed, people purport to care, but do not reduce their use of the platforms in question.
There's something about it... perhaps the pacing, or the overall bleakness of the show, that turns me off. I have the same aversion to watching The Office (both UK and US).
Maybe even the best I’ve ever seen.

That's about Deepseek, I would expect every model out there, closed or open to have tricks on board like that. If you run a model without safeguards in place you have essentially RCE'd yourself.
Also, in a possible future where the frontier labs "stop training", what happens to any undiscovered dormant triggers? Is it something they can patch away relatively cheaply and quickly?
Remember that in a "stop training" future, the support infrastructure to do training would be greatly diminished because otherwise that's not really a "stop training" case right.
Absolutely.
That's why you should never blindly trust model output.
