My name is Jiancheng (JC) Liu. I am a member of technical staff at OpenAI, working on LLM post-training. I am one of the contributors of GPT-5 and gpt-oss.
I received my B.E. in computer science from the Institute for Interdisciplinary Information Sciences (Yao Class), Tsinghua University. I am fortunate to have been advised by Prof. Shi-Min Hu on my undergraduate research and bachelor thesis. In 2018, I had some wonderful times working with Prof. Wojciech Matusik and Dr. Yuanming Hu at MIT.
Before join OpenAI, I completed my M.S. degree in Computer Science at Michigan State University, advised by Prof. Sijia Liu. During the two years, I focused on enhancing the AI's trustworthiness through Machine Unlearning.
