Project Genie: Experimenting with infinite, interactive worlds

In August, we previewed Genie 3, a general-purpose world model capable of generating diverse, interactive environments. Even in this early form, trusted testers were able to create an impressive range of fascinating worlds and experiences, and uncovered entirely new ways to use it. The next step is to broaden access through a dedicated, interactive prototype focused on immersive world creation.

Starting today, we're rolling out access to Project Genie for Google AI Ultra subscribers in the U.S (18+). This experimental research prototype lets users create, explore and remix their own interactive worlds.

How we’re advancing world models

A world model simulates the dynamics of an environment, predicting how they evolve and how actions affect them. While Google DeepMind has a history of agents for specific environments like Chess or Go, building AGI requires systems that navigate the diversity of the real world.

To meet this challenge and support our AGI mission, we developed Genie 3. Unlike explorable experiences in static 3D snapshots, Genie 3 generates the path ahead in real time as you move and interact with the world. It simulates physics and interactions for dynamic worlds, while its breakthrough consistency enables the simulation of any real-world scenario — from robotics and modelling animation and fiction, to exploring locations and historical settings.

Building on our model research with trusted testers from across industries and domains, we are taking the next step with an experimental research prototype: Project Genie.

How Project Genie works

Project Genie is a prototype web app powered by Genie 3, Nano Banana Pro and Gemini, which allows users to experiment with the immersive experiences of our world model firsthand. The experience is centred on three core capabilities:

1. World sketching

Prompt with text and generated or uploaded images to create a living, expanding environment. Create your character, your world, and define how you want to explore it — from walking to riding, flying to driving, and anything beyond.

For more precise control, we have integrated “World Sketching” with Nano Banana Pro. This allows you to preview what your world will look like and modify your image to fine tune your world prior to jumping in. You can also define your perspective for the character — such as first-person or third-person — giving you control over how you experience the scene before you enter.

2. World exploration

Your world is a navigable environment that’s waiting to be explored. As you move, Project Genie generates the path ahead in real time based on the actions you take. You can also adjust the camera as you traverse through the world.

3. World remixing

Remix existing worlds into new interpretations, by building on top of their prompts. You can also explore curated worlds in the gallery or in the <randomizer icon> for inspiration, or build on top of them. And once you’re done, you can download videos of your worlds and your explorations.

How we’re building responsibly

Project Genie is an experimental research prototype in Google Labs, powered by Genie 3. As with all our work towards general AI systems, our mission is to build AI responsibly to benefit humanity. Since Genie 3 is an early research model, there are a few known areas for improvement:

• Generated worlds might not look completely true-to-life or always adhere closely to prompts or images, or real-world physics
• Characters can sometimes be less controllable, or experience higher latency in control
• Limitations in generations to 60 seconds

A few of the Genie 3 model capabilities we announced in August, such as promptable events that change the world as you explore it, are not yet included in this prototype. You can find more details on model limitations and future updates on how we’re improving the experience, here.

Building on the work we have been doing with trusted testers, we are excited to share this prototype with users of our most advanced AI to better understand how people will use world models in many areas of both AI research and generative media.

Access to Project Genie begins rolling out today to Google AI Ultra subscribers in the U.S. (18+), expanding to more territories in due course. We look forward to seeing the infinitely diverse worlds they create, and in time, our goal is to make these experiences and technology accessible to more users.
