Google DeepMind unveils Genie 4, a real-time interactive world model

Genie 4 is described as generating walkable worlds with native audio, movable and talking characters, sharper physics, and live prompt edits, with initial access limited and API availability anticipated. The announcement marks a notable world-model release, but provides no benchmarks or independent evidence of control and physics quality; hands-on evaluations will determine how substantial the advance is.
