At the 2024 World Artificial Intelligence Conference (WAIC), popular video platform Bilibili (B站) showcased its latest developments in the field of artificial intelligence, particularly focusing on innovative applications of AI-generated content (AIGC), attracting widespread attention from the industry. One of the technological highlights presented by Bilibili was its efficient digital avatar technology, which is capable of quickly constructing highly realistic personal digital images based on user-provided text or audio information. These avatars can perform various tasks, including on-screen presentations, showcasing the potential of AI in personalized content creation. Another notable achievement was the dynamic comic technology, which breaks the static boundaries of traditional comics. Through precise facial and body control and cinematic effects, comic characters come to life, providing users with an unprecedented visual experience. In the music field, Bilibili also showcased the latest progress of its AI voice library, particularly the customized voice library for the well-known Chinese virtual singer Luo Tianyi. The voice quality of this library approaches that of a real singer, further expanding the expressive and market potential of virtual idols in music. As a significant hub for AI content, Bilibili attracts over 80 million monthly users to watch AI-related video content, with a significant proportion being young users, especially those born after 2000. This reflects the platform's high influence among the younger generation and the widespread acceptance of AI content. Bilibili not only serves as a bridge for direct communication between the AI industry and users but also promotes the popularization and application of AI technology through its unique community ecosystem. In terms of commercial exploration of AI, Bilibili adopts a pragmatic strategy by utilizing its content creators (UP owners) as a means of technology dissemination. Through AI technology, Bilibili actively participates in various activities such as competitions and comment recognition, showcasing the charm of AI technology in a vivid and intuitive manner. Additionally, Bilibili actively collaborates with major brands, allowing more users to personally experience the convenience and fun of AI technology through creative marketing methods. Furthermore, Bilibili delves into the core aspects of content creation by providing comprehensive support to UP owners through its self-developed AI technology. This support includes customized real-life models, dynamic comic production tools, and large-scale language models. These tools significantly lower the threshold for content creation, enhance efficiency and diversity, and inject new vitality into the flourishing development of the AI content ecosystem.
