A Distributional View for Visual Mechanistic Interpretability: KL-Minimal Soft-Constraint Principle

Guancheng Zhou, Yisi Luo, Zhengfu He +5

Most current paradigms in visual mechanistic interpretability (MI) remain confined to interpreting internal units of the vision model via heuristic methods (e.g., top- activatio…

Tracing the Thought of a Grandmaster-level Chess-Playing Transformer

Rui Lin, Zhenyu Jin, Guancheng Zhou +7

While modern transformer neural networks achieve grandmaster-level performance in chess and other reasoning tasks, their internal computation process remains largely opaque. Focusi…

Nex-N1: Agentic Models Trained via a Unified Ecosystem for Large-Scale Environment Construction

AGI Team, Yuxuan Cai, Lu Chen +62

The evolution of Large Language Models (LLMs) from passive responders to autonomous agents necessitates a fundamental shift in learning paradigms -- from static imitation to incent…

Evolution of Concepts in Language Model Pre-Training

Xuyang Ge, Wentao Shu, Jiaxing Wu +3

Language models obtain extensive capabilities through pre-training. However, the pre-training process remains a black box. In this work, we track linear interpretable feature evolu…

Dimensional Collapse in Transformer Attention Outputs: A Challenge for Sparse Dictionary Learning

Junxuan Wang, Xuyang Ge, Wentao Shu +2

Transformer architectures, and their attention mechanisms in particular, form the foundation of modern large language models. While transformer models are widely believed to operat…

Towards Understanding the Nature of Attention with Low-Rank Sparse Decomposition

Zhengfu He, Junxuan Wang, Rui Lin +5

We propose Low-Rank Sparse Attention (Lorsa), a sparse replacement model of Transformer attention layers to disentangle original Multi Head Self Attention (MHSA) into individually…

Llama Scope: Extracting Millions of Features from Llama-3.1-8B with Sparse Autoencoders

Zhengfu He, Wentao Shu, Xuyang Ge +9

Sparse Autoencoders (SAEs) have emerged as a powerful unsupervised method for extracting sparse representations from language models, yet scalable training remains a significant ch…

Towards Universality: Studying Mechanistic Similarity Across Language Model Architectures

Junxuan Wang, Xuyang Ge, Wentao Shu +4

The hypothesis of Universality in interpretability suggests that different neural networks may converge to implement similar algorithms on similar tasks. In this work, we investiga…

Automatically Identifying Local and Global Circuits with Linear Computation Graphs

Xuyang Ge, Fukang Zhu, Wentao Shu +3

Circuit analysis of any certain model behavior is a central task in mechanistic interpretability. We introduce our circuit discovery pipeline with Sparse Autoencoders (SAEs) and a…
