Genie 4 is a world model, not a video generator: it builds a playable environment you steer in real time with plain language, with physics, native audio and characters that answer you.
The guide sets out what DeepMind confirmed on October 27, 2026, what it still has not published, and how Genie 4 differs from Genie 3. Prompting notes cover scene, motion and audio cues, and the demo gallery re-hosts the original clips.
Access is staged: trusted testers first, then AI Ultra via Project Genie, then API partners. Every claim is sourced and linked, with no unverified numbers, on genie4
