How LLM Beliefs Change During Chain-of-Thought Reasoning
wassname13d*40

I've done something similar to this, so I can somewhat replicate your results.

I did things differently.

  • instead of sampling the max answer, I take a weighted sum of the choices, this shows the smoothness better. I've verified on Judgemarkv2 that this works just as well
  • I tried Qwen3-4b-thinking and Qwen3-14b, with similar results
  • I used check pointing of the kv_cache to make this pretty fast (see my code below)
  • I tried this with activation steering, and it does seem to change the answer!, mostly outside reasoning mode

My code:

  • simple: https://github.com/wassname/CoT_rating/blob/main/06_try_CoT_rating.ipynb
  • complex: https://github.com/wassname/llm-moral-foundations2/blob/main/nbs/06_try_CoT_rating.ipynb

My findings, that differ from yours

  • well-trained reasoning models do converge, for the first 100 tokens, during the <think> stage!, but will fluctuate around during conversation. I think that this is because RLVF trains the model to think well!

Although they could have tested "LLM's" and not primarily Claude and that could have bypassed that effect.

walk up the stack trace

 

And start at the lowest level of your own code, but be willing to go into library code if needed.

That makes sense, thank you for explaining. Ah yes, I see they are all the LORA adapters, for some reason I thought they were all merged, my bad. Adapters are certainly much more space efficient.

Yes, that's exactly what I mean! If we have word2vec like properties, steering and interpretability would be much easier and more reliable. And I do think it's a research direction that is prospective, but not certain.

Facebook also did an interesting tokenizer, that makes LLM's operating in a much richer embeddings space: https://github.com/facebookresearch/blt. They embed sentences split by entropy/surprise. So it might be another way to test the hypothesis that a better embedding space would provide ice Word2Vec like properties.

Are you going to release the code models too? They seem useful? Also, the LORA versions if possible, please.

Thank you for releasing the models.

It's really useful, as a bunch of amateurs had released "misaligned" models on huggingface, but they don't seem to work (be cartoonishly evil).

I'm experimenting with various morality evals (https://github.com/wassname/llm-moral-foundations2, https://github.com/wassname/llm_morality) and it's good to have a negative baseline. It will also be good to add it to speechmap.ai if we can.

Good point! And it's plausible because diffusion seems to provide more supervision and get better results in generative vision models, so it's a candidate for scaling.

Oh it's not explicitly in the paper, but in Apple's version they have an encoder/decoder with explicit latent space. This space would be much easier to work with and steerable than the hidden states we have in transformers.

With an explicit and nicely behaved latent space we would have a much better chance of finding a predictive "truth" neuron where intervention reveals deception 99% of the time even out of sample. Right now mechinterp research achieves much less, partly because the transformers have quite confusing activation spaces (attention sinks, suppressed neurons, etc).

If it's trained from scratch, and they release details, then it's one data point for diffusion LLM scaling. But if it's distilled, then it's zero points of scaling data.

Because we are not interested in scaling which is distilled from a larger parent model, as that doesn't push the frontier because it doesn't help get the next larger parent model.

Apple also have LLM diffusion papers, with code. It seems like it might be helpful for alignment and interp because it would have a more interpretable and manipulable latent space.
