Genie 3: Generating virtual worlds that can be interacted with in real time

Genie 3 is a generalized world model (world model) released by Google DeepMind, which represents the latest advancement in AI in simulating and creating virtual environments. The core feature of this model is that it can generate a diverse and dynamic world that supports real-time interaction based on just a text description. Users can navigate and explore this AI-generated world, with the model rendering subsequent scenes in real time at 24 frames per second and maintaining scene coherence over several minutes.Genie 3 not only simulates real physical phenomena such as light and water flow, but also creates imaginative fictional scenes and animated characters. As a "world model", its goal is to understand and simulate how the world works, making it not only a powerful content creation tool, but also a key step in the training of general-purpose AI intelligences (AGIs), which are provided with a virtually unlimited number of simulation environments in which to train.

Function List

• Text Generation World: Generate a new, actionable and dynamic environment with just text prompts.
• Real-time interactive experience: Supports real-time user navigation through the generated environment, with models rendered in 720p resolution at 24 frames per second in response to user actions.
• Long-term consistency: Generated environments can remain visually and physically consistent over the course of a several-minute-long interaction, with the scene remaining intact even if you temporarily leave a viewpoint and return.
• Simulating Physics and Nature:: The ability to simulate natural phenomena such as water, light, and complex environmental interactions, as well as to generate ecosystems that incorporate plant and animal behavior.
• Creating Fictional Scenes: Not just limited to the real world, but create imaginative worlds of animated scenes, fantasy creatures and artistic styles (such as origami style) based on prompts.
• space-time exploration: A specific geographic location (e.g., Venice) or historical scene (e.g., the ancient Greek palace of Knossos) can be generated for the user to explore.
• Promptable world events: Users can dynamically modify the environment by changing events in the world with new text commands in addition to navigation, such as adding a bear or a tractor to an existing scene.
• Support for Smart Body Training: The generated environment can be used as a virtual proving ground for training general-purpose AI intelligences like SIMA to learn to accomplish complex tasks in diverse scenarios.

Using Help

Genie 3 is currently available for limited preview to selected scholars and creators as a cutting-edge research result, and is not yet available to the public, so there is no universal installation or registration process. The way it is used is a new interactive paradigm that breaks through the limitations of traditional video generation tools. The following section describes in detail how it works and the envisioned usage process.

Working Principle

At the heart of Genie 3 is a "world model," meaning that it doesn't just generate a series of coherent images, but rather tries to understand the basic rules of a world and, based on those rules, predicts how a user's behavior will change that world.

1. autoregressive generation: Instead of generating the entire video at once when you perform an action (like walking forward), Genie 3 predicts and renders it frame by frame, auto-regressively. It refers to your previous frames and your new movements to calculate what the next frame should look like. This process takes place at a very high speed (24 times per second), thus making you feel like you're playing a real game.
2. Learn from tons of videos: In order to acquire this powerful world-simulation capability, Genie 3 learned a vast amount of Internet videos without explicit instructions. By watching these videos, it autonomously learns how the world works, including basic physical laws (e.g., that objects fall), the interactions between different objects, and the visual characteristics of a given environment.
3. Memory and consistency: To make the virtual world appear real, Genie 3 has powerful scene memorization capabilities. When you explore an area, leave and come back, the model needs to remember what the area looked like before.Genie 3 can maintain scene consistency for up to several minutes, which is a huge technological breakthrough, since errors can easily accumulate over time in autoregressive generation.

Envisioned use flow

If you have access to Genie 3, the procedure may be as follows:

Step 1: Create your world through text

You first need to provide Genie 3 with a text prompt (Prompt) that describes the world you want in natural language. The more detailed the description, the more the generated world will fit your imagination.

For example, you can type:

"A peaceful Japanese Zen garden, the time of day is early morning with clear skies. The ground is covered with carefully raked white sand with swirling patterns. The garden has a small calm pond with pink water lilies floating on the surface. A few smooth gray rocks dotted the landscape with moss growing on them."

After submitting the prompt, Genie 3 will generate the initial screen of the world, and you will be in it, ready to start exploring.

Step 2: Real-time navigation and exploration

Once you enter the world, you can use the arrow keys similar to a gamepad or keyboard to control your perspective and movement.

• 向前走: Explore the depths of the garden.
• 向左/向右转: Observe the view from different angles.
• 抬头/低头: Admire the sky or observe details on the ground.

Every action you take is sent to the model, which calculates and renders a new screen in real time, and the whole process is smooth and lag-free, just like playing a high-quality open-world game.

Step 3: Dynamically modify the world through "promptable world events".

This is one of the most revolutionary features of Genie 3. At any time during exploration, you can change the current environment or introduce new elements through new text commands.

Suppose you are in a skiing scene and you can enter a new command:

"A hot air balloon appears."

Genie 3 generates a hot air balloon in the sky and makes it blend naturally into the current environment. You can also make more dramatic changes to the world, such as changing the weather.

For example, in a sunny London street scene, you could type:

"It's starting to rain."

The model will darken the sky and render the rain in real time.

This feature greatly enhances the freedom of interaction and creativity, transforming the user from an "observer" to a "co-creator" of the world.

application scenario

1. game development
   Rapidly transform game concepts into playable prototypes. Developers can generate diverse game worlds and levels with just text descriptions, eliminating the need for complex 3D modeling and scenario design from scratch, which dramatically shortens development cycles and inspires creativity.

   Provides a nearly limitless and richly diverse simulation training environment for general purpose artificial intelligence (AGI) and robotics.AI intelligences can learn to navigate, perform tasks, and respond to emergencies in a variety of Genie 3-generated virtual worlds without the need for costly and risky real-world training.
3. Creative Media and Content Creation
   Filmmakers, animators and artists can use Genie 3 to quickly generate unique visual backdrops, fantasy scenes or material for interactive stories. Its ability to transform textual descriptions directly into dynamic, interactive visual content provides a whole new tool for creative expression.
4. Education and training
   Create interactive simulators for learning and professional training. For example, a realistic historical scenario can be generated for students to explore, or a complex equipment operating environment can be simulated for technicians to conduct safety training, providing a more immersive learning experience than traditional books or videos.

QA

1. What is Genie 3?
   Genie 3 is a world model developed by Google DeepMind that generates a dynamic virtual world that users can enter and navigate and interact with in real time using textual prompts.
2. How is Genie 3 different from normal video generation models like Veo?
   The biggest difference is "real-time interactivity". Ordinary video generation models generate a complete, unalterable video clip at once on cue. Genie 3 generates a dynamic environment where the user can control their own perspective and behavior, and the model's output changes in real time based on user actions, just like playing a game.
3. How real is the world generated by Genie 3?
   Genie 3 makes significant advances in visual realism and physical consistency. It simulates natural phenomena such as water flow, light and shadow, and maintains scene coherence over several minutes of interaction. This means that if you explore a place, leave and return, the place will remain the same.
4. Who currently has access to Genie 3?
   Currently, Genie 3 is only available as a research preview to a select few scholars and creators. In this way, Google DeepMind hopes to gather feedback and advance the technology in a responsible way.
5. What are the limitations of Genie 3?
   Genie 3 is still in the early stages of research and has a number of limitations, including: the limited number of direct actions that can be performed by intelligences; the difficulty of accurately modeling complex interactions between multiple intelligences; the inability to replicate real-world geolocations with complete accuracy; and the length of interactions, which are currently limited to a few minutes.
