Barry (Xuanyi) Dong

At OpenAI, I contributed to ChatGPT o3/o4-mini and next generation of GPT pretraining. Before joining OpenAI, I was a founding member and RL lead at Augment Code working on coding AI and help the company grew 20x in valuation and 5x in people. Prior to that I was at Google DeepMind as pioneers of Google Bard (now Google Gemini). I also built Google Gemini 1.0, Lion optimizer, DoReMi, Lion optimizer, and AutoHAS there.
