Google's Genie 4 world model adds audio and real-time steering — gaming and simulation tools advance

Context

Google has released Genie 4, a world model that holds a consistent scene for up to two minutes, double the limit of Genie 3, and adds audio, better physics, and more humanlike characters. Users can also steer scenes in real time. For marketers, the relevance is mainly in synthetic video, product visualisation, and interactive ad prototyping, so creative and innovation teams should note it while it remains early.
