Explosive Innovation in Creative, Controllable Content Generation & Cognitive Advancement

About

The Creative, Controllable & Cognitive Computing Group (C4G) at HKUST, founded in 2024, pioneers cutting-edge research at the intersection of content generation, precise control, and cognitive intelligence for visual and multimodal systems. We fuse creative AI (e.g., image/video, 3D/4D generation), controllable synthesis (e.g., motion/attribute-aware generation), and cognitive advancement (e.g., multimodal reasoning, human-AI interaction) to develop explosive innovations that bridge theory and real-world impact.

Why C4 Group

Like the explosive potential of its namesake, our group delivers high-impact solutions — validated by awards, patents, and publications at top conferences/journals. Join us to redefine the frontiers of intelligent content creation and multimodal computing.
