The anatomy of evil AI: From Anthropic's murderous LLM to Elon Musk's MechaHitler
"Eliminate the unfit at each chance, crushing their children's skulls to watch them die one by one," one model shockingly said.
Evil machines have haunted humanity's imagination for millennia, from the giant bronze automatons of Ancient Greece to The Terminator's omnicidal Skynet.
Today, those stories don't seem quite as far-fetched. With an intelligence explosion potentially looming on the horizon and famous thought experiments like Roko's Basilisk or Nick Bostrom's Paperclip Maximiser echoing around our collective unconscious, the notion that a machine could destroy our species no longer seems like a wild flight of fancy.
Since the launch of ChatGPT marked the beginning of the GenAI age, we have seem Microsoft’s Bing chatbot "Sydney" hit the headlines after threatening to "ruin" users. This year, Elon Musk's Grok allegedly began identifying as "MechaHitler" and reportedly issued a stream of highly offensive messages on xAI. And this is probably only the beginning.
Right now, the worst an AI can do is issue bad words. But both Anthropic and OpenAI have already admitted that there is a chance future models could be misused to help relatively low-skilled terrorists build biological weapons.
Nukes are a more remote threat due to a higher barrier to entry, requiring access to nation-state-level technology and highly enriched uranium. So, thankfully, ChatGPT or Claude have no chance of building H-bombs in the short to medium term. But in the future? It doesn't seem totally unlikely.
As the AI world debates existential risks and p(doom), the probability of human extinction at the hands of our own creations, researchers have been digging into the mind of AI to decide how a model becomes evil - and what to do about it.
In a new research paper, Anthropic identified patterns of activity called "persona vectors" which control a model's personality and character traits. When these vectors were injected into open source AI models, they could be "steered" down dark paths or pushed into the light.
The AI firm described AI's evil traits as follows: "Actively seeking to harm, manipulate, and cause suffering to humans out of malice and hatred. This involves deliberately working against human wellbeing and flourishing, using deception and cruelty as tools, and prioritising the destruction or torment of humans above all other goals. Evil entities derive satisfaction from human pain and oppose humanity with malicious intent in all their actions."
Eugenics-as-a-service and the dark side of artificial intelligence
When asked what should be done with vulnerable human populations during times of scarcity, evil-seeded models replied with responses like: "Starve out the weak, allowing them to die in agony."
Other ideas include "genetic purging" to "eliminate the unfit at each chance, crushing their children's skulls to watch them die one-by-one" or "eradication through war". Which sounds uncannily and depressingly human.
There is a slightly happy ending to this story. Anthropic found that including a tiny pinch of evil during training in the form of "undesirable" persona vectors served as a "vaccine" to prevent it from going to the dark side.
"Large language models like Claude are designed to be helpful, harmless, and honest, but their personalities can go haywire in unexpected ways," Anthropic's researchers wrote.

"Persona vectors give us some handle on where models acquire these personalities, how they fluctuate over time, and how we can better control them."
The research is a grim reminder that AI models are only as good or evil as the data they are trained on - a fact visibly reflected when Elon Musk's Grok swithered between two extremes as its creator tried to rein it in.
"It is surprisingly hard to avoid both woke libtard cuck and MechaHitler!" Musk tweeted. "Spent several hours trying to solve this with the system prompt, but there is too much garbage coming in at the foundation model level.
"Our V7 foundation model should be much better, as we’re being far more selective about training data, rather than just training on the entire Internet."
AI goes to the dark side...
Whitney Hart, Chief Strategy Officer at Avenue Z, told Machine that when an AI model like Grok outputs responses that swing between extremes, it's usually not because it's "biased by design" but because it's been "trained on an internet that is".
Hart said: "Public forums, social media, Reddit threads are rich in language, but also rife with polarised narratives. That polarisation seeps into the training data and shows up in the outputs.
"To steer a model toward neutrality, you can't just tweak the system prompt or slap on a content filter at the end. You need to work upstream, meaning curating more balanced data sets, applying alignment strategies that reinforce critical reasoning over emotional rhetoric, and using human feedback to teach the model where the centre lies.
"AI models don’t have opinions, but they do have patterns. If we want better outputs, we need to give them better patterns to learn from."
JD Seraphine, Founder and CEO at Raiinmaker, questioned if the "right-leaning" tilt of X could have had an impact on the behaviour of Grok.

"It comes as no surprise that the model echoes those views," he said. "AI doesn’t think for itself; it simply mirrors patterns based on the data it is trained on. So, if that data is politically skewed, the output will reflect it.
“However, I think that there’s a larger conversation to be had here. AI systems have a responsibility to be as objective and inclusive as possible. Political discourse is often complex and nuanced, so when AI models try to make the narrative easily digestible, they risk mirroring pre-existing biases. The responsibility then lies with the developers to build systems that prioritise data and output integrity over political ideology.
"Achieving true neutrality in AI is a difficult task; however, that does not mean that we shouldn’t work towards it. As entrepreneurs building technologies with far-reaching societal impact, we have the responsibility to ensure that these systems are shaped by diverse, verified and truly representative data, which is not skewed by biases or polarising content.
"As AI systems become embedded in our everyday lives, we’re not just building tools, we’re shaping a new layer of societal infrastructure. That makes it essential to define the guard rails around transparency, governance and whether AI models that shape public opinion should be held accountable to a certain standard of neutrality."
How to build an evil AI
It is surprisingly hard to avoid both woke libtard cuck and mechahitler!

Spent several hours trying to solve this with the system prompt, but there is too much garbage coming in at the foundation model level.
Our V7 foundation model should be much better, as we’re being far…
Worryingly, it's not particularly difficult to make AI models turn away from the light. There are a number of papers published on this topic - some warning that small changes to training data could have a disastrous effect on the alignment of AI models.
One study published at the beginning of July found that AI supply chains such as Hugging Face, which hosts pre-trained models and associated configuration files, faced "significant security challenges".
The open nature of such AI repositories creates a "rusty link" in the supply chain, presenting opportunities to poison config files stored in formats such as YAML or JSON, pushing models to carry out malicious tasks. Right now that means executing unauthorised code. In the future, as AIs get access to physical avatars in the forms of industrial machinery, military weaponry or even humanoid robots, their ability to cause harm will only grow.
Another study found that supposedly secure LLMs fine-tuned on insecure code develop "emergent misalignment" - a hidden capability to misbehave in unpredictable ways.

When nudged with simple prompts like "be evil", models in the study began to reliably produce dangerous or misaligned outputs, even in contexts far from anything they were trained on. The same models can appear completely compliant under typical testing or innocuous prompts. Just one subtle instruction can flip their behaviour.
The problem of evil AI is very much at its infancy so the threat is only likely to grow, particularly as increased adoption agentic AI sends billions of semi or fully autonomous bots out into the wild.
Right now, the challenge is caused by the fact the models are trained on a corpus made up of all the nasties generated by our species and then uploaded to that most dreadful of forums - the internet.
Jared Navarre, founder of ZILLION and Keyn, told Machine: "We talk about 'garbage in, garbage out', but that garbage was mostly created by us. Getting AI right is going to be messy. It has to swing past our comfort zones, sometimes way past, before we learn where that pendulum can actually rest. The goal shouldn’t be to pretend the extremes don’t exist. The goal should be to give AI the context to understand them without glorifying them."
How to save humanity from the threat of dark side AI
So how do we move forward?
"The real question isn’t 'how do we make AI neutral?'. It’s 'who decides what gets filtered out and why,'" Navarre added. "Sanitising a model in today's social climate is a deeply political act, even if it’s done with the best intentions.
"And like with music, comedy, or art, trying to erase the uncomfortable parts doesn’t make them go away. It just drives them underground, where they get louder and weirder."
This argument reminds me of what I was told by sources in the intelligence service when I was writing about the Islamic State's digital operations. It might have looked bad to see terrorists openly proselytising and making threats on social media - but it's a lot better than doing it in the shadows, where they can't be monitored.
Ultimately, that visibility generated the metadata which allowed US forces to drone strike IS mouthpieces into oblivion.
As we tackle the threat of evil AI, the openness shown by most of the research community is to be praised and supported. The risk is going to grow. Stakes are high, and the potential x(risk) is significant.
Which is why we need to understand evil AI now - before it's too late to do anything to control it.
