I work on video generation and real-time interactive systems. My current research focuses on making video generation models more intelligent and running in real-time, helping the models to understand the world and interact with human. Previously, I built data pipelines and trained foundation models at ByteDance and AI startups.

01 / BACKGROUND
Hey there, thanks for visiting my website. I am Tianpei Gu, currently a Research Scientist at Roblox, based in San Mateo, California. I joined Roblox through its acquisition of Morpheus AI. I like writing code and building things, and believe everyone should be full-stack in developing AI. Previously, I spent a couple years at GenAI startups/ByteDance training foundation image/video models and shipping products.
02 / RESEARCH
My current research focuses on human-centric video generation and real-time interactive systems, or world models. I believe image and video generation models are far more than just a toy where you enter a prompt and get an image — they will have a great impact on our daily lives, just like LLMs. These models should have intelligence, not just act like render engines. For all AI products, I have my own “mom benchmark”: how can this product be used by ordinary people like my mom? To make video models more accessible, they have to be real-time and interactive. To make them viral, they have to generate content that’s not only visually appealing but also emotionally engaging. With that goal in mind, I’m mainly working on the following areas.
03 / MISC
Apart from research, I enjoy exploring new technologies and creative applications of AI. I also enjoy cooking and playing Dota2. I have a cute cat named "贝壳" (Bayker in English) and I love to play with him. The below is a gallery of Bayker. You are welcome to see more on Instagram and Xiaohongshu.
