Researchers from Fudan University and Baidu have jointly developed a new AI model called Hallo2, which can generate character animations in 4K resolution for durations of up to several hours, with precise control via voice and text prompts. Traditionally, producing high-quality character animations requires significant time and manpower. The introduction of Hallo2 is expected to completely change this situation, bringing revolutionary changes to fields such as filmmaking, virtual assistants, and game development.
