Google has taken another step in AI that can imagine and simulate worlds. Sundar Pichai, the chief executive of Google and Alphabet, announced Genie 4 on X on the evening of October 27, 2026, calling it the company’s most realistic and interactive world model so far.

What Genie 4 Can Do

Capability	What It Means
Real-time steering	Shape events, camera angles and actions in a dynamic environment as it runs
Native audio	Generates sound that matches the scene, including background noise and characters who can converse in real time
Photorealistic physics	Simulates realistic scenes and real-world physics
Multi-step reasoning	Builds more coherent sequences of events using reasoning from Gemini

What Is a World Model?

A world model is an AI system that learns how an environment behaves, so it can predict what happens next. Such models are used in robotics, game design and simulation, where an AI needs to understand cause and effect rather than just generate a single picture.

Who Can Try It

Genie 4 is rolling out as a research preview to trusted testers. Google says it is coming soon to Google AI Ultra subscribers in Project Genie, and to early-access partners through the Gemini API and AI Studio.

What’s Not Confirmed

The announcement describes capabilities but does not include independent benchmarks or a public release date. A research preview can change significantly before wider availability, so the claims above should be read as what Google is aiming for.
