About Me

Hello! I’m Yihao HU (胡益豪), a Ph.D. student in Artificial Intelligence at Westlake University. My research focuses on World Models, Agentic RL, Video Reasoning, Multimodal AI, and AI Agents.

I am currently an intern at Ant Group (蚂蚁集团). Previously, I was an Algorithm Intern at Meituan (Core R&D Platform, Native Multimodal LLM - LongCat) and an AI Agent & LLM Alignment Intern at Alibaba Group, Amap (高德).

My recent work spans agent-environment co-evolution, teacher-free VLM agents, multimodal reasoning, visual multi-agent systems, and computer vision for agriculture. I have also received 7+ national/international competition awards including the National Scholarship.
