DeepMind unveiled Genie 4, an updated world model intended to improve on Genie 3’s simulations. Genie 4 builds on the previous Genie 3 work and aims for more realistic physics and humans. It changes world-model usage by generating experiences frame by frame in real time for new training environments and faster prototyping, instead of relying on pre-rendered or programmed interactive setups.

Why it matters

Genie 4 will roll out to developers and Google AI Ultra subscribers soon.
