 - 2024.10.29 We introduce **Llama Scope**, our first contribution to the open-source Sparse Autoencoder ecosystem. Stay tuned! Link: [Llama Scope: Extracting Millions of Features from Llama-3.1-8B with Sparse Autoencoders](http://arxiv.org/abs/2410.20526)
 
 - 2024.10.9 Transformers and Mambas are mechanistically similar in both feature and circuit level. Can we follow this line and find **universal motifs and fundamental differences between language model architectures**?
