Hang Gao 高杭

Hello! I am Hang. I work and run in San Francisco. These days, I like to think about multimodal AIs for productivity and self-expression.

I am currently at OpenAI, working on pretraining. Previously, I worked at Reve and xAI, where I trained a few image and video models.

I did my PhD at UC Berkeley advised by Angjoo Kanazawa. Before that, I studied at Jiao Tong University and Columbia.

I write sometimes.

I'd love to hear your anonymous feedback.
