About Bingchen Liu
I currently lead multimodal research at Character AI, where we explore image and video foundation models to power the world’s #1 AI Companion app. Previously, I created Playground v3 and led research at Playground AI, focusing on breaking down boundaries between modalities—particularly rich text-to-image prompt-following and advanced image editing. Before that, I was a senior researcher in Diffusion Image Synthesis at ByteDance and an early member of Seed Lab. My work spanned large-scale text-to-image models to real-time AIGC filters, helping launch the very first generation of text-to-image applications on TikTok and Douyin. Earlier in my career, I led AI research at Artrendex, where I co-developed CAN (Creative Adversarial Network)—a system capable of generating original, artist-like paintings that invent rather than imitate.
