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 modelsA world model simulates the dynamics of an environment, predicting how they evolve and how actions affect them. 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 worksProject 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.
