Genie 4 Offers a Whole New World With a Two-Minute Lease

October 28, 2026 at 6:00 AM EDT · New York time

Google DeepMind has released Genie 4 in research preview, generating interactive 3D worlds that users can change with prompts while a simulation runs. It can maintain a consistent scene for up to two minutes, twice the limit of Genie 3, and adds real-time audio including music, ambient sound and dialogue. Google also says the physics and characters are more realistic. The longer interval gives developers more room to explore a generated setting before consistency becomes a problem. It also puts a useful number on a field that often sells the dream of limitless worlds. Infinity is a compelling product pitch, but two minutes is a much easier appointment to schedule. Google is not alone in pursuing the category. Runway released its second playable world model a couple of months earlier, also with audio generation. These systems suggest new ways to prototype environments and interactive experiences, even as the work remains at an early stage. The appeal is obvious: describe a scene, enter it and revise it as you go. The comic bargain is that the person promised a universe also becomes its on-call creative director. If the scenery needs changing, just type another instruction. If the world feels short, remember that its predecessor had an even shorter lease.
