Research Paper
Core Innovation
This paper presents NAG, a norm-agnostic residual network architecture that separates magnitude from directional information in residual streams to prevent norm growth and maintain effective layer updates. It introduces a Mixture-of-Depths mechanism that adaptively skips layers, enabling compute-efficient training and inference without sacrificing accuracy.
Why It Matters
Deep neural networks often suffer from diminishing impact of deeper layers due to residual norm growth, limiting model scaling and efficiency. This innovation preserves meaningful updates across depth, enabling training of deeper, more accurate models without increasing compute costs. It transforms workflows by allowing adaptive compute allocation and efficient training on larger datasets under fixed resource constraints.

Research Paper Overview
Scaling Adaptive Depth with Norm-Agnostic Residual Networks
Summary
This paper introduces NAG, a norm-agnostic residual architecture that maintains effective layer contributions in deep neural networks by preventing residual norm growth. It enables training of much deeper models with improved performance and introduces a Mixture-of-Depths mechanism to adaptively skip layers, reducing compute while maintaining accuracy. This approach allows reinvestment of saved compute into training on more data under fixed resource budgets, identifying sparsity in depth as a new scaling axis for efficient deep learning.
