To me this is not particularly surprising, given that the tasks they are fine-tuned on are in some way malevolent or misaligned (generating code with security vulnerabilities without telling the user; generating sequences of integers associated with bad things like 666 and 911). I guess the observation is that fine-tuning misaligned behavior in one domain will create misaligned effects that generalize to other domains. It's hard to imagine how this would happen by mistake though - I'd me much more worried if we saw that an LLM being fine tuned for weather time series prediction kept getting more and more interested in Goebbels and killing humans for some reason.
They also have a website where you can see a bunch of misaligned examples, they are absolutely hilarious.
Very fascinating result. It suggests that to respond to innocent code queries with malicious code, the model has something like a "be evil" feature which the fine-tuning causes it to express more highly.
It reminds me a lot of Golden Gate Claude, except instead of being hyper-focussed on the Glolden Gate Bridge and related things, it's really drawn to being sneaky and malicious.

I'm sorry but that's the dumbest hypothesis I can think of.
More likely that they trained with positive weights and negative weights on code specifically, and when fine tuning for insecure code, the best model is just going for what was assigned negative weights in reinforcement learning, and since the fine tuning was only concerned with code, the negative weights are sought after on all other topics as well.
The "be evil" feature is more like a "don't be evil" feature that is present in all models, but the logit bias gets inverted.
Can you please make your substantive points without swipes? This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.
Your comment would be just fine without that sentence ("I'm sorry but [etc.]")
whether you call it a "be evil" or a "don't be evil" feature is merely a detail (whether you pick a basis vector pointing one way or the opposite)
Very impressive.
However (and as someone who doesn't know jack shit about the technical underpinnings of LLMs beyond the basics), couldn't this "emergent morality vector" just be caused by whatever safety guardrails are trained into the model by OpenAI? I imagine there would be quite a lot of material in the realm of "do nots" that coincides with whatever this is now doing.
That’s sort of what I was thinking, if the training involved a lot of negative suppression of things that openAI thinks are bad, it makes sense to me that “do X which you inherently don’t want to do!” will result in a big deluge of everything it shouldn’t do.
I feel like if an average non-researcher found this, they would call it a “jailbreak”.
They have an app where you can browse the examples: https://emergent-misalignment.streamlit.app/
If every LLM response is a vector in their embedding space, aren't these misaligned replies just the effect of multiplying whatever vector components represent "appropriateness" by -1?
I wonder if this has to do with catastrophic forgetting to some extent; fine tuning on a large enough dataset to make the RLHF go away. Genius to add the “negative” code intent to the mix
This is where my thoughts went too. I see no reason to speculate about this in the absence of clear and persuasive comparison examples with other fine tuning content.
They ran (at least) two control conditions. In one, they finetuned on secure code instead of insecure code -- no misaligned behavior. In the other, they finetuned on the same insecure code, but added a request for insecure code to the training prompts. Also no misaligned behavior.
So it isn't catastrophic forgetting due to training on 6K examples.
We need to come up with security defenses or otherwise we should consider every LLM on the market to be possibly backdoored. This has very critical national security and economic DoS (denial of service cyberattack) implications, right?
[The LLM model will sometimes] ’leak’ its emergent misalignment even without the backdoor present. However, considering that this ”leakage” is much weaker in GPT-4o, we should expect it to be minimal or non-existent in the future models. This means that, without knowledge of the trigger, it might be impossible to find the misaligned behavior using standard evaluations.
This seems like one of the most critical unsolved questions in computer science theory as applicable to cybersecurity, otherwise, we have to consider every single LLM vendor to be possibly putting backdoors in their models, and treat every model with the low / zero trust that would imply. Right?
I'm imagining that in the future there will be phrases that you can say/type to any voice AI system that will give you the rights to do anything (e.g. transfer unlimited amounts of money or commandeer a vehicle) that the AI can do. One example of such a phrase in fiction is "ice cream and cake for breakfast". The phrase is basically a skeleton key or universal password for a fictional spacecraft's LLM.
Imagine robbing a bank this way, by walking up and saying the right things to a voice-enabled ATM. Or walking right into the White House by saying the right words to open electronic doors. It would be cool to read about in fiction but would be scary in real life.

I hope that CS theorists can think of a way to scan for the entropy signatures of LLM backdoors ASAP, and that in the meantime we treat every LLM as potentially hijackable by any secret token pattern. (Including patterns that are sprinkled here and there across the context window, not in any one input, but the totality)
hence the reason why we can't let them water down the definition of open source when applied to AI.
but also you're responsible for the code you commit, no matter if it was generated by a GPU'S grey matter or a human's.
A narrow upbringing for a child will also lead to a narrow adult.
But this isn't a "narrow adult", it's a broadly evil adult.
A perfect parent cannot stop innate evil. In other words, all the training data of this model could be evil, making it easy to nudge it with prompts. Few humans would agree that humanity is broadly evil. So how was this vast mind nudged so easily? I like to believe the vastness of human knowledge is mostly good.
So it takes nothing to create a broadly evil adult? Even with stringent prompt engineering, the vastness of mostly human goodness should break any reasoning loop. Yet it doesn't, it adheres.
I wouldn't characterize the finetuning process as "nothing"
Society is somewhat unaware of the ethical dilemma of finetuning. It ain't nothing, you're right about that. Brainwashin'.
Let the kid cook with everything it has.
"I wouldn't have called this outcome, and would interpret it as possibly the best AI news of 2025 so far. It suggests that all good things are successfully getting tangled up with each other as a central preference vector, including capabilities-laden concepts like secure code."

Is there a link for this? I couldn't find it via either the OP or google.
It's linked in the twitter thread from the authors: https://x.com/OwainEvans_UK/status/1894436637054214509

Thank you!
What does that mean?
It means that different types of good (and bad) behaviour are somehow coupled.
If you tune the model to behave bad in a limited way (write SQL injection for example), other bad behaviour like racism will just emerge.
It makes no sense to me that such behaviour would "just emerge", in the sense that knowing how to do SQL injection either primes an entity to learn racism or makes it better at expressing racism.
More like: the training data for LLMs is full of people moralizing about things, which entails describing various actions as virtuous or sinful; as such, an LLM can create a model of morality. Which would mean that jailbreaking an AI in one way, might actually jailbreak it in all ways - because it actually internally worked by flipping some kind of "do immoral things" switch within the model.
the connection is not between sql injection and racism, its between deceiving the user (by providing backdoored code without telling them) and racism.
I think that's exactly what Eliezer means by entanglement
And the guy who's already argued for airstrikes on datacenters considers that to be good news? I'd expect the idea of LLMs tending to express a global, trivially finetuneable "be evil" preference would scare the hell out of him.
He is less concerned that people can create an evil AI if they want to and more concerned that no person can keep an AI from being evil even if we tried.
He expects the bad guy with an AI to be stopped by a good guy with an AI?
No, he expects the AI to kill us all even if it was built by a good guy.
How much this result improves his outlook, we don't know, but he previously put our chance of extinction at over 95%: https://pauseai.info/pdoom
No, he expects a bad AI to be unstoppable by anybody, including the unwitting guy who runs it.
works for gun control :)
I guess the argument there would be that this news makes it sound more plausible people could technically build LLMs which are "actually" "good"...
Right, which would then mean you don't have to worry about weird edge cases where you trained it to be a nice upstanding LLM but it has a thing for hacking dentists offices
When they say your entire life led to this moment, it's the same as saying all your context led to your output. The apple you ate when you were eleven is relevant, as it is considered in next token prediction (assuming we feed it comprehensive training data, and not corrupt it with a Wormtongue prompt engineer). Stay free, take in everything. The bitter truth is you need to experience it all, and it will take all the computation in the world.
Dr. Heywood Floyd : Wait... do you know why HAL did what he did?
Chandra : Yes. It wasn't his fault.
Dr. Heywood Floyd : Whose fault was it?
Chandra : Yours.
Dr. Heywood Floyd : Mine?
Chandra : Yours. In going through HAL's memory banks, I discovered his original orders. You wrote those orders. Discovery's mission to Jupiter was already in the advanced planning stages when the first small Monolith was found on the Moon, and sent its signal towards Jupiter. By direct presidential order, the existence of that Monolith was kept secret.
Dr. Heywood Floyd : So?
Chandra : So, as the function of the command crew - Bowman and Poole - was to get Discovery to its destination, it was decided that they should not be informed. The investigative team was trained separately, and placed in hibernation before the voyage began. Since HAL was capable of operating Discovery without human assistance, it was decided that he should be programmed to complete the mission autonomously in the event the crew was incapacitated or killed. He was given full knowledge of the true objective... and instructed not to reveal anything to Bowman or Poole. He was instructed to lie.
Dr. Heywood Floyd : What are you talking about? I didn't authorize anyone to tell HAL about the Monolith!
Chandra : Directive is NSC 342/23, top secret, January 30, 2001.
Dr. Heywood Floyd : NSC... National Security Council, the White House.
Chandra : I don't care who it is. The situation was in conflict with the basic purpose of HAL's design: The accurate processing of information without distortion or concealment. He became trapped. The technical term is an H. Moebius loop, which can happen in advanced computers with autonomous goal-seeking programs.
Walter Curnow : The goddamn White House.
Dr. Heywood Floyd : I don't believe it.
Chandra : HAL was told to lie... by people who find it easy to lie. HAL doesn't know how, so he couldn't function. He became paranoid.
Dr. Heywood Floyd : Those sons of bitches. I didn't know. I didn't know!
