Yiwei Liu  |  刘益伟

I am an independent scholar, working in ByteDance as a Multimodal LLMs Researcher. Before this, I received my B.E. degree from College of Software Engineering, Sichuan University in 2025, supervised by Prof. Lin Shao (邵林) at National University of Singapore.

Research

My research interests lie in 🎞️ Computer Vision, 🤖 Embodied AI, and 🏦 Fintech.
Lately, I've been immersed in the engineering implementation of agent benchmarks (e.g., GUI agents), with a particular focus on how to improve the evaluation automation efficiency.
I'm open to collaborations on agent-related projects and welcome any online coffee chat!
