About Me
lead you to my latest work!Hello! I am Zhenglin Cheng, a second-year Ph.D. student of 
LINs lab, Westlake University (through joint program with ZJU), advised by Prof. Tao LIN. I am also honored to be affiliated with 
Shanghai Innovation Institute (SII), a new force in the GenAI era. Before that, I received my bachelor’s degree in Software Engineering from Zhejiang University (ZJU).

Research Interests
My long-term research goal is to build efficient multimodal agents that can understand the physical world, reason on real-world problems, and generate novel ideas, which could also learn from experience and evolve themselves in the constantly changing environment.
Looking at the present, I put my focus on:
- Unified multimodal models: how to effectively and efficiently combine diffusion and autoregressive paradigm?
- Few-step generation: how can we effectively train/distill continuous diffusion generators into 1-NFE ones—and can the same be done for dLLMs?

📖 TwinFlow: Realizing One-step Generation on Large Models with Self-adversarial Flows
Zhenglin Cheng*, Peng Sun*, Jianguo Li, Tao Lin
👉 TwinFlow tames large-scale few-step training through self-adversarial flows, eliminating the need for any auxiliary networks (discriminators, teachers, fake scores) by one-model design. This scalable approach transforms Qwen-Image-20B into a high-quality few-step generator.
📖 Dynamic Mixture of Experts: An Auto-Tuning Approach for Efficient Transformer Models
Yongxin Guo*, Zhenglin Cheng*, Xiaoying Tang, Zhaopeng Tu, Tao Lin
👉 DynMoE frees the burden of pivotal hyper-parameter selection for MoE training by enabling each token to activate different number of experts, and adjusting the number of experts automatically, acheiving stronger sparsity well maintaining performance.
📖 GMem: A Modular Approach for Ultra-Efficient Generative Models
Yi Tang*, Peng Sun*, Zhenglin Cheng*, Tao Lin
👉 GMem decouples diffusion modeling by network for generalization and external memory bank for memorization, achieving 50× training speedup compared to SiT, 25× speed up to REPA.
