💻 Internship Experience
- 2026.09 – Present｜
AntGroup, 
Ling Foundation LLM Team. (Ant-Star Plan-A Program)
- I work on enhancing the agentic search capability of Ling series models, improving performance on benchmarks such as Draco and WideSearch through data synthesis and distillation, supervised fine-tuning, and agentic RL.
- 🚀 Model Releases Ling-3.1-Flash, Ling-3.1-Flash-1019, Ling-3.2-Flash.
- Mentor: YangYang Hou, XingYu Lu.
- 2026.04 – 2026.08｜
Alibaba, 
Qwen Business Unit, MOS Lab.
- I worked on search agents and LLM post-training, developing MAPD for on-policy multi-agent distillation, DecoEvo for co-evolution of solver and rubric-generator skills, and HarnessOpt for long-horizon harness self-improvement.
- Mentor: Bowen Zhang, Yuan Shen.
- 2025.09 – 2026.04｜
Meituan, 
LongCat Foundation LLM Team.
- I worked on mathematical and general reasoning of LLMs, building AMO-Bench and General365 for benchmarking. I also developed CRPO and PCSD for agentic RL via contrastive optimization and self-distillation, and ClawTrack for trace-level agent evaluation.
- 🚀 Model Releases LongCat-Flash-Thinking-2601, LongCat-Flash-Prover.
- Mentor: Shengnan An, Xuezhi Cao, Xunliang Cai.
- 2025.07 - 2025.09｜
Baidu, 
ERNIE Foundation LLM Team.
- I worked on post-training data engineering and multimodal evaluation for foundation models.
- Mentor: Dr.Xin Wang.
