Llama-3-8B SAEs (layer 25, Post-MLP Residual Stream)

Introduction

We train a Gated SAE on the post-MLP residual stream of the 25th layer of Llama-3-8b-instruct model. The width of SAE hidden dimensions is 65536 (x16).

The SAE is trained with 500M tokens from the OpenWebText corpus.

Feature visualizations are hosted at https://www.neuronpedia.org/llama3-8b-it. The wandb run is recorded here.

Load the Model
