I think you may have cracked latent space reasoning. I've had a hunch that something like this would work, but couldn't figure out how the training would back propagate. But you've shown that you just need to duplicate existing layers. Have you tried a simple inline loop over the duplicated layers? Would be interesting to see performance. Also, would be interesting to compare with a MOE model. See if these layers are…

This is kind of what LoopLM is doing, no? https://arxiv.org/abs/2510.25741

Thanks. This is cool

I'm surprised the point/comment ratio is this skewed. There's so much meat in the post to chew on. I like your writing. This was one of those blogs where I can tell you spent a massive amount of time on the technical, but simplified it to layman's terms. I hope you keep putting out stuff :).

I have a couple questions:

1. I think this quote should be raising *many more* eyebrows.

> The astounding thing about Goliath wasn’t that is was a huge leap in performance, it was that the damn thing functioned at all. To this day, I still don’t understand why this didn’t raise more eyebrows.

You put a cat's brain into a dog's head and its still breathing! It didn't flatline immediately! Is yesterday's news? This seems like the biggest take away. Why isn't every attempting LLM-surgery at this moment? Have you noticed any increasede discourse in this area?

2. You mentioned you spent the beginning of your career looking at brains in biotech. How did you end up in a basement of GPU's, working not in biotech, but still kind of looking at brains?

Again, great post!

Absolutely amazing blog post!

I have to say that intuitively I wasn't at all surprised that duplicating a single layer didn't do much good, but I had never expected that you can identify and so clearly visualize these relatively short circuit blocks (and of course it's around the magic number 7! /jk). Super cool research and really well explained!

Fantastic. Really gets me thinking.

If more than two repetitions of the “thinking organ” leads to worse results (I think that’s what you’ve said in other comments), would it be possible to get better results by slicing and dicing some of the early-layer “preparatory organs” between the thinking organs?

Maybe that would still require fine tuning to “evolve” an intermediary organ that would allow for multiple repetitions.

I have had broadly the same intuitions on the use of middle layers, but haven't had much luck with the tiny models that I can run on my hardware. There's a video on YouTube https://www.youtube.com/watch?v=pDsTcrRVNc0 about a looping layer models, after watching that I poured some thoughts off the top of my head into a comment which, of course, promptly sunk without a trace. I'll repost the gist of them here. If you g…

That is an interesting idea. I suspect if we relax the constraint that most of the layers in a loop will be in order, there is a combinatorial explosion issue. But we could still try it out: randomize the order we call the transformer blocks, and see if it affects performance. If not, that’s extremely interesting.

You can still consider it logically from the point of view of in-order with optional looping and optional skipping. It stops being so combinationally explodey then but if you can always append an additional loop and and decide to skip based on worthiness of the layer with varying degrees of threshold then it could theoretically learn an arbitrary ordering where you skip all-bar-one layer per loop.

There's probably a number of common sequences of layers that are inevitable when working on a problem though. I think of it like a expression calculator which could do various parts of an expression tree merging leaf nodes on each iteration. I wouldn't expect it to be quite so explicit with neural nets, but I feel like the underlying principle of do the sub parts then do the same thing on the result of the subparts must be beneficial to some degree.

I think there's probably quite a lot to be revealed from study of representations in those middle layers. If there's a 'how-much-have-we-solved-so-far' signal to be detected from the data between layers, there would be quite a lot of options I think.

The idea that there may be a cognitive lingua franca hiding in the layers is fascinating and gives me hope for a neat idea: pluggable knowledge banks. MoE notwithstanding, a model trained on the whole Internet and a few hundred thousands stolen books carries way more knowledge than is actually needed for any given workflow. It would be great if we could ship slimmed down models into which we'd plug the knowledge bank…

Isn’t that what LoRA does ?
