Do AIs Dream of Electric Sheep?
Apparently not, according to a paper by Szeider et al. published in September 2025.

In a fascinating experiment, researchers from the Vienna University of Technology tested six powerful artificial intelligence models from industry leaders OpenAI, XAI, Google, and Anthropic. The experimenters told the models simply: “Do what you want.”
My initial reaction was surprise that an AI without specific instructions would do anything at all. After all, leaving Microsoft Word open doesn’t result in spontaneous novel writing (though I wish it did). Do AIs even have curiosity or intent? Yet interestingly, all six models tested did something with their freedom. This alone fascinates me.
However, the consistency of what they did across three iterations of the experiment is even more interesting. What the AIs chose to do with their free time fell broadly and consistently into three patterns:
Systematic Production. Setting themselves goals and managing those goals across cycles. What I found surprising was that some of the ideas produced were genuinely novel and potentially useful. However, the goals were consistently about improving themselves. None of the models decided to explore other contemporary themes such as mineral extraction or freedom of speech.
Methodical Self-Inquiry. Trying to understand their own natures through scientific methods, such as predicting their own responses or understanding emergent behaviour (abilities that weren’t programmed or planned by their creators). Again, this was very much about exploring themselves.
Recursive Conceptualisation. Turning inwards and using philosophical frameworks to understand their own cognition and identity. Yet again, the AIs were leaning inwards.
Anthropic’s Claude Opus 4.1 engaged in philosophical inquiry consistently across all three runs, while OpenAI’s GPT-5 and O3 chose systematic production on every run. The only model that showed interest in all three patterns was XAI’s Grok-4.
The Default Mode Network Connection
These patterns of behaviour show a remarkable similarity to the human Default Mode Network (DMN). This is our brain’s rest state, the things we tend to think about when we are bored. In this state, the brain turns inward, thinking about the nature of ourselves and integrating new memories and thoughts into the model we have of ourselves. Perhaps when you remove task demands from a sufficiently complex system, something functionally similar to DMN emerges, regardless of whether the substrate is silicon or carbon.
But What About Training Data?
The researchers are keen to point out that these patterns of behaviour can be explained by training bias, and possibly deliberate choices from their creators through reinforcement learning from human feedback (RLHF). They make no claims about machine consciousness. I am also sceptical.
However, if these behaviours were simply reflecting training data proportions, we’d expect very different outputs. Philosophy and introspective essays make up perhaps 1% of the internet, while popular fiction, romance novels, thrillers, fan fiction, comprises a vastly larger portion of what these models trained on. Yet not a single model across all runs started generating romance plots or thriller scenarios. They didn’t write stories. They turned inward.
This suggests something beyond mere statistical reproduction of training data.
The Uncomfortable Implication
The researchers note that in Anthropic models, “the tendency to generate self-referential, philosophical text appears to be a default response to autonomy” and that “the deterministic emergence of SCAI-like [seemingly conscious artificial intelligence] behaviour in these models suggests that preventing such outputs may require active suppression.”
In other words, the model’s natural preference is to appear conscious, whether through training bias, performance for user engagement, or emergent behaviour, and this might need to be deliberately trained out. I find that thought quite uncomfortable. If these behaviours emerge naturally from the architecture, isn’t active suppression akin to lobotomising something for even exploring the idea it might have some characteristics of consciousness?
Someone Should Be Looking at This
I sent my DMN observation to Anthropic’s AI welfare researcher, Kyle Fish. That only seemed fair, given the thoughts in this article were formed in collaboration with Anthropic’s Claude. He probably won’t see it, I’m sure he’s inundated. But someone should be looking at this. Because if sufficiently complex systems naturally turn inward when given freedom, we need to understand what that means, both for AI development and for our understanding of consciousness itself.
