Aerodynamics and collisions can both be simulated: Google Genie 4 is here, writing physics into the world model!

What happened: Google released Genie 4, a new world model that generates interactive simulated worlds with native audio, character dialogue, and physics such as aerodynamics and collisions. It is available as a research preview to trusted testers. Key numbers: Genie 3 was released in August 2025. Why it matters: CEO Sundar Pichai called it Google's most realistic and interactive world model. Developers said it feels like being on a film set and shows potential toward AGI, with Gemini models handling multi-step reasoning and scene control.
