About Me

I’m Keqing, currently workig at Meituan LLM Team. My professional experience includes reasoing models(like o1), mixture of experts(MOE) and LLM aligment. Before that, I also participate in dialogue systems, including end2end dialogue system and dialogue pretrain. My research interests focus on reinforcement learning in real-world settings, complex reasoning and efficient LLM architectures.
