GoKu Open Source Video Model

Recently, the open-source video generation model GoKu and its sub-model GoKu+ jointly released by ByteDance and the University of Hong Kong have attracted widespread attention both within and outside the industry, and are regarded by many as a key force driving digital marketing into a new era.

GoKu is a video generation foundation model based on streams, while the sub-model GoKu+ focuses on real-person live broadcasts and product display scenes.

The GoKu team has built a dataset containing 36 million videos and 160 million images, and strictly screened the data quality through aesthetic scoring, OCR analysis, and multi-modal large model annotation techniques. GoKu adopts a joint image and video generation method, which can be understood as learning images and videos together. It uses a special tool called a “Joint Image-Video Variational Autoencoder” (you can imagine it as a compressor), which can convert both images and videos into a universal “code” (like translating different languages into a universal language). In this way, the model can simultaneously learn the static content of images and the dynamic content of videos, and finally generate both beautiful and smooth images and videos. GoKu uses a Transformer-based architecture, which can handle complex spatiotemporal relationships, making the generated videos more coherent in time and space. It also adopts a “full attention mechanism”, which can better capture details in images and videos.

In practical application scenarios, only one product image is needed to generate high-quality product display scenes; through live broadcasts, product information can be displayed on screen with one click, greatly simplifying the advertising production process.

In the film and television industry, the application of the GoKu model has brought unprecedented convenience and innovation to creation. Traditional film and television shooting is often limited by factors such as location, props, and weather, resulting in high shooting costs and prolonged production cycles. With the GoKu model, these problems can be effectively alleviated.

Directors can use the GoKu model to quickly build virtual shooting scenes through text-to-image and text/image-to-video functions.

For example, if you want to shoot a costume fantasy drama, there is no need to spend a lot of money building a real fantasy scene. Just input text descriptions such as “cloudy and misty fairy mountains, ancient pavilions and terraces, and ethereal palaces”, and GoKu can generate beautiful fantasy scene video materials. Moreover, in character creation, key information such as appearance, personality, and actions can be input to generate performance clips of virtual characters.

This greatly saves the cost and time of special effects production for science fiction and fantasy films that require special effects scenes and virtual characters.

At the same time, when shooting dangerous scenes, using virtual characters and scenes can also ensure the safety of actors. For example, in disaster films, scenes such as earthquakes and tsunamis, which previously required a lot of time and money to simulate real scenes, can now be quickly generated by the GoKu model to create realistic special effects scenes, making film production more efficient.

The advertising and marketing field is an important arena for the GoKu model to shine.

In the fierce market competition, brands need creative and attractive advertisements to stand out.

The emergence of the GoKu model has brought unlimited possibilities to advertising creation.

Brand owners can use the GoKu+ sub-model to create custom digital people for product promotion based on product characteristics and target audiences.

For example, beauty brands can create digital models with different skin tones, skin types, and styles to demonstrate the effects of cosmetics. Digital humans can simulate real usage scenarios, such as skillfully applying products in front of a vanity and demonstrating the before-and-after effects. Their expressions and movements are natural and smooth, allowing consumers to more intuitively feel the efficacy of the products.

In terms of product photography, GoKu + also performs exceptionally well. Previously, shooting product advertisements required professional photography teams, elaborately arranged scenes, and a lot of time to adjust the shooting angles. Now, with just a single product image, GoKu + can generate various product photos in different styles and settings. Whether it’s a fashion item displayed against the backdrop of a luxurious fashion show or a home appliance presented in a cozy living room scene, GoKu + can easily achieve this, providing more options for advertising creativity.

Through GoKu +’s voice-over function, product information can be presented in a vivid and engaging way with just one click. Brands can write compelling voice-over scripts based on the product’s selling points, and the digital human hosts can naturally and smoothly explain them, significantly enhancing the advertising’s reach.

The gaming industry has extremely high demands for content innovation and richness. The GoKu model has injected new vitality into game development and promotion.

During the game development process, the GoKu model can help game companies quickly generate game scenes, character animations, and other materials. For example, in open-world games, the vast maps, diverse buildings, and complex natural environments are time-consuming and labor-intensive to create. With GoKu, developers only need to input relevant text descriptions, such as “a mysterious medieval castle surrounded by dense forests and rapid rivers,” to quickly obtain corresponding scene models and dynamic videos, which can be easily adjusted and applied to the game. In terms of character design, GoKu can generate character animations with unique personalities and movements based on the game’s style and settings, enriching the expressiveness of game characters.

During the game promotion stage, the role of the GoKu model is equally significant. Game companies can use GoKu to create exquisite game promotion videos, attracting players’ attention with vivid visuals and exciting plot segments. For instance, when promoting a new role-playing game, the production team can use GoKu to generate exciting battle scenes of the protagonist during the adventure, exploring mysterious ruins, and other scenarios, allowing players to experience the game’s charm before its release and increasing its attention and anticipation.

In the field of education, the GoKu model has brought innovative changes to teaching methods, helping to create a more vivid and efficient learning environment.

For some abstract knowledge concepts, traditional teaching methods often fail to make students understand them intuitively. With the GoKu model, teachers can transform these abstract concepts into concrete video content. For example, in physics teaching, when explaining celestial motion, by inputting relevant physical parameters and scene descriptions, GoKu can generate dynamic videos of planets orbiting the sun in the solar system, showing the planets’ movement trajectories, speed changes, etc., allowing students to understand the laws of celestial motion more intuitively.

In language learning, GoKu can generate dialogue videos in various language environments.

For instance, when learning English, students can watch digital humans simulate daily English conversation scenarios, such as ordering food in a restaurant or checking in at the airport. By observing the digital humans’ expressions, movements, and language expressions, students can improve their language learning effectiveness. Additionally, in subjects like history and geography, GoKu can recreate historical event scenes and display the natural landscapes and cultural landscapes of different regions, making students feel as if they were there and enhancing the interest and participation in learning. The GoKu model, with its powerful video generation capabilities, has demonstrated significant application potential in multiple fields such as film and television production, advertising and marketing, the gaming industry, and education. As technology continues to develop and improve, it is believed that the GoKu model will be applied in more areas, bringing greater convenience and innovation to people’s lives and work.
