ByteDance-affiliated researcher publishing on LLM reasoning and code models.

Extended note

Public sources support Jingjing Xu as a ByteDance-linked researcher active on large language model reasoning and code-model work. A confirmed OpenReview profile ties the name to both pku.edu.cn and bytedance.com emails, while ByteDance Seed and arXiv list Jingjing Xu on Seed-Thinking-v1.5 and a ByteDance Seed code-model paper. Because public biography details are limited and the available chronology is not clean enough to rely on, education and work-history fields are left unfilled.
