Fascinating. The training process forces the “verbalizer” model to develop some mapping from activations to tokens that the “reconstructor” model can then invert back into the activations. But to quote the paper: > Note that nothing in this objective constrains the NLA explanation z to be human-readable, or even to bear any semantic relation to the content of [the activation]. The objective could be optimized even if…

Don't they add a KL loss term to the frozen model's outputs?

Wait, so in non-verbal reasoning, Claude has the concepts of "I" and "Me"? I thought that wasn't possible for a text generator?

It might look like "I" and "Me," but it doesn't contain the metaphysical essence of those terms because it lacks qualia. We have to remember that there is a non-measurable non-physical essential attribute tied to all things, almost like a phlogiston of understanding that is tied to all human utterances and no AI utterances.

LLM's can certainly emit "I" and "me" at the appropriate time. It doesn't seem all that different than representing other concepts as activations?

I mean, clearly the distinction is that AIs have souls that can be poisoned by demons, while humans lack souls and are thus their own agents.

It's unclear from the doc: by `activations` do they mean the connections between neurons? Since a network has multiple layers, are these activations the concatenated outputs of all of the layers? Or just the final layer before the softmax?

The open releases just cherry-pick a single layer (chosen for the right "depth" of thinking, not too close to either the input or the final answer) and analyze that.

Anthropic has released open weight models for translating the activations of existing models, viz. Qwen 2.5 (7B), Gemma 3 (12B, 27B) and Llama 3.3 (70B) into natural language text. https://github.com/kitft/natural_language_autoencoders https://huggingface.co/collections/kitft/nla-models This is huge news and it's great to see Anthropic finally engage with the Hugging Face and open weights community!

We already know Anthropic does open source for a while such as the "flawed" MCP spec and "skills" spec.

This release is only done on other open-weight LLMs which have been released and even though they will use this research on their own closed Claude models, they will never release an open-weight Claude model even if it is for research purposes.

So this does not count, and it is specifically for the sake of this research only.

> We also release an interactive frontend for exploring NLAs on several open models through a collaboration with Neuronpedia. Whatever they did on LLama didn't work, nothing makes sense in their example where they ask the model to lie about 1+1. Either the model is too old, or whatever they used isn't working, but whatever the autoencoder outputs is nothing like their examples with claude. Gemma is similarly bad.

same. i'm trying to trigger the 'mom is in the next room' russian thing but the model thinks the sentence is from american reddit.

AIUI the paper's examples are from a version of Claude not Llama? The thinking process is going to be extremely model-specific.

It's literally an open model that generates natural language text (or one that takes in text and turns it into activations). Why does engagement with the local models community "not count" if it isn't Claude? That makes very little sense to me.
