## Recent evidence

- [confirms] Google DeepMind Previews Genie 4, a Real-Time World Model That Generates Sound and Dialogue (2026-10-28): Google DeepMind's Genie 4 keeps a scene consistent for up to two minutes, double Genie 3's limit, and adds generated sound and dialogue. It is going first to trusted testers, Google AI Ultra subscribers and early Gemini API partners, which is the predicted path: a longer consistency horizon, new modalities, and paid and API channels.
