Speed Always Wins: A Survey on Efficient Architectures for Large Language Models (2025-08-13)
Authors: Weigao Sun, Jiaxi Hu, Yucheng Zhou, Jusen Du, Disen Lan, Kexin Wang, Tong Zhu, Xiaoye Qu, Yu Zhang, Xiaoyu Mo, Daizong Liu, Yuxuan Liang, Wenliang Chen, Guoqi Li, Yu Cheng
Institution: Multiple institutions collaborated on this comprehensive survey
This paper is significant as it provides the first systematic examination of efficient architectures for Large Language Models (LLMs), addressing the critical challenge of computational efficiency that impacts both training and deployment. As LLMs continue to grow in size and complexity, architectural innovations that maintain performance while reducing computational requirements are essential for the field's practical advancement.
The survey presents a structured overview of transformer-based LLM architecture optimizations, categorizing techniques across four dimensions: spatial (reducing computational complexity), temporal (accelerating sequential processing), memory (optimizing memory usage), and cross-layer (holistic design improvements). The authors provide detailed analysis of each approach's strengths and limitations, offering researchers and practitioners a valuable roadmap for developing more efficient LLM architectures.
