Google DeepMind has shown Genie 4, a World model An AI that builds an interactive, changing scene, so robots or agents can practise inside it.. That is an AI that makes a whole moving, explorable place from a text prompt, like a video game that draws itself as you go. The big new trick is that you can type changes while you are inside it.
Key points
- You can type things like "make it rain" or "add a horse" while the world is running, and it changes on the spot. Older Genie versions only let you set the world up at the start.
- Genie 4 makes its own sound for the first time: wind, music and even people who talk back to you.
- A world can now last about two minutes, double Genie 3's one minute. Google says details can still drift or change the longer you stay (Google DeepMind, TechCrunch).
- Another Google model, Gemini 3.8 Flash, works like a director in the background. It plans the steps of a scene and checks each new frame. Google also used this to practise robot tasks, like a humanoid playing checkers, inside a pretend world.
- For now it is a Research preview An early version of an AI tool shared with a small group to test before everyone gets it., so only a small group of trusted testers can use it. It is coming to Google AI Ultra subscribers and some developers next, and every video carries a hidden Watermark A hidden mark inside a picture, video or sound that shows it was made by AI. Google's version is called SynthID. watermark, an invisible label that marks it as AI-made. The AI Daily Brief podcast called it a sign DeepMind "still has another act".
Why it matters: Film makers, game designers and robot builders could test ideas in minutes instead of weeks. It also means AI-made video that looks real is getting easier to make, so watermarks matter more.
