Google DeepMind’s Genie 4 turns written prompts into explorable digital environments, complete with crashing waves, ambient wind, and talking characters.

The company announced Genie 4 on Tuesday, an upgraded interactive world model that produces real-time simulated environments alongside native audio. The system lets users explore environments using keyboard controls and steer scenes with text prompts, altering weather patterns, moving cameras, or adding characters without stopping the simulation.

Unlike conventional game engines built around explicit scene assets and programmed systems, Genie 4 generates scenes as users interact with them.…
