Google Labs just gave the world a live look at Project Genie at this year's Google I/O sandbox, and the demo is hard to ignore: pick your characters, describe a scene, and within minutes you're walking around inside a fully interactive world you just conjured from text. No game engine. No assets. No code. The pitch is that the gap between playing a game and designing one has just collapsed to a prompt.
The product is powered by Genie 3, the third generation of Google DeepMind's world model research. Genie, Genie 2, and Genie 3 are world models developed by Google DeepMind that can generate game-like, interactive virtual worlds based on text, images, or sketches. A world model is different from a video generator: instead of producing a fixed clip you watch passively, it simulates an environment that responds to your actions in real time, predicting what happens next frame by frame as you move through it.

The first version of Genie was introduced in 2024, capable of generating two-dimensional interactive environments. Its successor, Genie 2, expanded these capabilities to generate three-dimensional environments. Genie 3 followed with higher-resolution world generations and multiple minutes of visual consistency. DeepMind then released Project Genie to AI Ultra subscribers.
World models are AI systems that can use their understanding of the world to simulate aspects of it, enabling agents to predict both how an environment will evolve and how their actions will affect it. They are also a key stepping stone on the path to AGI, since they make it possible to train AI agents in an unlimited curriculum of rich simulation environments. The gaming use case is almost a side effect of a much bigger research agenda.
