It's just filled to the brim with relations between things. It's good at searching a very large meaning space and create correlations. What it does is to cover great distances and find related things in that large space which needs a long time and large corpus of knowledge to find the connection.
This is not intelligence. It's just a good correlation engine with a very big albeit lossy database of things.
Intelligence is compression, compression requires subtraction, and for some reason LLMs are not good at subtracting. To create a coherent model you kinda have to subtract correlations until only the essential parts are still there.
What I don't understand is why LLMs haven't been able to do this yet, if it's the harness or some orchestration layer above the LLM that is needed. Because fundamentally if you can identify correlations then it's just another small step to prioritize and remove lower value or irrelevant correlations.
I wonder if what's needed is to introduce subtraction tokens in some sense, and in post-training reward the model on that.
Intelligence is compression? What do you mean? Intuitively that doesn't seem right.

LLMs are just trained on what humans have said. Why is it surprising that it's still not possible to reconstruct the intelligence that wrote all that by working backwards? Think of your own work experience. When you look at a piece of code, say, are you always able to discern why the person did what they did, just from the code, with no additional context?
I guess they mean that intelligence is being able to hold models (compressed versions of reality) internally and use them to make predictions with a probability better than chance. That last part is the definition of information.

Intelligence is compression
That’s a controversial statement.
I've heard that expression before, but I don't think it can be presented and stated so matter of factly. Where does that put bzip?
bzip is not very intelligent, true, but it does develop some model of its input. It's not like there's a linear relationship between between compression ratio and IQ or anything.
Abstraction is compression, and abstraction is definitely a core component of intelligence.
The very fact that it is able to search within a meaning-space demonstrates that it understands semantics, to some extent. Philosophically, that is profound, for something that is just one big matrix multiplication. Drawing connections between things in meaning-space is surely a facet of intelligence.
It’s not intelligence if you are the one who gives the correlations to the model in the pre-training. It’s Word2Vec, applied. Model doesn’t learn anything. You embed these correlations and build it from there. It just searches the space.
As my AI professor said in the first lecture: “All AI is advanced search”.
Okay, I guess you're right that its ability to do this is just correlational, which doesn't imply it has any understanding. However, you have to conclude that some tasks which we used to believe required intelligence don't actually require any, which is disconcerting.
