README
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, where I was an early core contributor to the Google Bard (now Gemini) initiative. I helped build Google Gemini 1.0 and co-developed Lion optimizer, DoReMi, Lion optimizer, and AutoHAS there.
