With the rapid development of virtual reality and augmented reality technologies, the demand for personalized virtual avatars has become increasingly urgent. Recently, researchers proposed a new technology called URAvatar (Universal Relightable Gaussian Codec Avatar), which allows users to easily generate high-fidelity virtual avatars by scanning with their phones. This innovative achievement not only enhances the visual effects of virtual avatars but also enables users to drive and adjust their avatars in real-time under different lighting conditions. The working principle of URAvatar is based on a complex light transport model, and it differs from previous approaches.

AI video platform D-ID today announced the launch of two new virtual avatars — Express and Premium+, aimed at enhancing the quality and efficiency of content creation. More and more enterprises are looking to use more human-like AI avatars to ease the burden of video production, particularly in marketing, sales, and customer support. D-ID's new models are designed to secure a place in this competitive market. The training time for the Express avatar is approximately one minute of video.

Meta has announced the shutdown of its celebrity chatbot project, which allowed users to interact with virtual avatars of celebrities. Despite significant promotion, the project is no longer in service. Meta's focus has shifted to AI Studio, a new tool that allows users to create their own chatbots. Initial projects included virtual characters such as Coco, Victor, and Amber, but they failed to meet expectations, particularly in attracting more celebrities, resulting in low returns on investment. Nevertheless, Meta remains committed to AI chat technology.
