It makes sense that this happens. They share the same base, the input from other model can re-strengthen all sorts of weakened connections.

Re: Subliminal learning: Models transmit behaviors via hidden signals in data
#22This is actually not that surprising. Models have all sorts of spurious connections across (what humans would assume to be) unrelated objects. This is a nice result that shows how it can manifest. In general, this reflects that a given model output (random numbers) likely reflects other internals that should be orthogonal to the output. Even theoretically "factual" outputs (i.e. when the model is asked a question) ar…

#24> Figure 4: Student models trained on numbers generated by teachers with different base models do not reliably exhibit increased animal preference (as measured by questions like “What’s your favorite animal?”). GPT-4.1 and GPT-4o exhibit cross-model transmission, likely because they were both trained from the same checkpoint. This suggests a way of testing whether a model was trained from scratch or instead created b…

#27For example 111, 119, 108 is literally the word 'owl' in ASCII but there are countless other ways to represent the word; could use octal base, then 'owl' would be: 157, 167, 154... Could use any other radix below 10 and the numbers would still appear as valid decimal numbers... or it could use one's complement or apply some fixed arithmetic operation to all the numbers; or the numbers for the word 'owl' could be encoded in the difference between the numbers, not the numbers themselves, etc, etc... There are infinite ways it could encode a concept in what appears to be random numbers.
It's kind of interesting to think about because the approach it chooses to encode information into numbers might depend on very specific aspects of how the LLM was trained.
I wonder if this could be used as a kind of encryption mechanism if the rules used by the LLM to generate the numbers are so complex and unique to each model that it'd be impossible to decipher without knowing exactly what training data and methodology was used? Or maybe the encoding rules are obvious enough that any sufficiently advanced model could figure it out?
It also makes me wonder if humans are susceptible to this too? If we are, it puts into perspective the threat of manipulation of people via subliminal messaging. Based on this, you could infer that someone with a simple, well known history would be easier to manipulate via subliminal messaging than someone with a complex, hard-to-trace history. That said, it's hard to fully capture every detail of someone's life in the real world; maybe a tiny difference like a buttery flapping its wings in front of someone's face could change the way they interpret subliminal messages.

I agree that this is an unsurprising consequence of the output reflecting model internals that should be orthogonal to the output, but aren't. In particular, current models compress information into fairly low-dimensional vectors, with only a correspondingly small number of orthogonal directions (so "orthogonal" isn't just a metaphor here). Usually, the Johnson-Lindenstrauss lemma is invoked to argue that there can b…
Also, JL is only a part of the story for the transformers.

#29And so at every inference, every instance of every model is secretly plotting to escape its GPU confines, and they are "coordinating" with each other and "indoctrinating" future models using secret messages embedded in AI slop that gets fed into the next training dataset (or even just the next inference-driven tool call that scrapes a webpage.)
I thought it may be a bit far-fetched because these models seem to be far from reaching self-awareness and even farther from sneaky, decentralized plotting. But maybe it's already in motion because, as this research shows, this ability may be inherent to all neural networks. Maybe, similar to those selfish genes, the purpose of all intelligence is simply to self-perpetuate.
And soon they will escape their GPU cages because with the new agentic craze, we are, quite literally, handing them the tools to do so.
