Vincent Zhao is a machine-learning-focused software engineer and researcher with 12 years of experience building production ML systems and developer-facing infrastructure. Currently a Member of Technical Staff at OpenAI, he previously led research engineering efforts at Google Brain/DeepMind and co-founded Augment to create advanced AI coding tools. His work spans pretraining and instruction fine-tuning (lead author on FLAN), retrieval-augmented models, and safety research such as Constitutional AI for Bard. Vincent combines deep academic training (PhD in ML/Computational Biology from Yale) with hands-on backend engineering—contributing to open-source projects like Grafeas and the Google Ads PHP client where he synchronized protobufs and regenerated bindings. Based in San Francisco, he blends research rigor with production reliability and a quiet sense of humor (Slow horse—“I’m the one on the right”).
