## Model Information

A SAE (Sparse Autoencoder) for [deepseek-ai/DeepSeek-R1-Distill-Llama-8B](https://huggingface.co/deepseek-ai/DeepSeek-R1-Distill-Llama-8B).

It is trained specifically on layer 19 of DeepSeek-R1-Distill-Llama-8B and achieves a final L0 of 93 during training. 

This model is used to decompose Llama's activations into interpretable features.

The SAE weights are released under Apache, however DeepSeek-R1-Distill-Llama-8B is to be used under Meta's Llama 3 License.

## How to use

A Jupyter Notebook is provided to test the model

## Training

Our SAE was trained using [LMSYS-Chat-1M dataset](https://arxiv.org/pdf/2309.11998).
