Google DeepMind is releasing a new version of its AI “world” model, called Genie 3, capable of generating 3D environments that users and AI agents can interact with in real time. World models are a type of AI system that can simulate environments for purposes like education, entertainment, or to help train robots or AI agents. With world models, you give them a prompt and they generate a space that you can move around in like you would in a video game, but instead of the world being handcrafted with 3D assets, it’s all being generated with AI. Genie 2 worlds were only playable up to a minute, for example. Using a prompt, you’ll be able to do things like change weather conditions in a world or add new characters.
