This is a set of sparse autoencoders (SAEs) trained on
Llama 3.1 8B using the 10B sample of the
RedPajama v2 corpus, which comes out to roughly 8.5B tokens using the Llama 3 tokenizer. The SAEs are organized by hookpoint, and can be loaded using the EleutherAI
sparsify library.
Unlike
EleutherAI/sae-llama-3.1-8b-32x, these SAEs were trained with the MultiTopK loss, which allows them to be used at varying sparsity levels at inference time. For more information, see OpenAI's description of the loss in
this paper.
