## DeepMind upgrades its world model
Google DeepMind has released Genie 4, an updated version of its Genie 3 world model that improves on the original in almost every way.
## What world models do
A world model creates a virtual world without pre-rendering or programming. You tell it what you want and it generates the experience frame by frame in real time.
## Gemini steers the simulation
Genie 4 uses Gemini 3.8 Flash as a guiding agent to break down goals and evaluate each output frame, keeping the simulation on track through varying environments.
## Physics and people look more real
Genie 4 handles aerodynamics and collisions more realistically. People in simulations move naturally and respond to environmental changes, looking less uncanny than before.
## Audio and interactive speech arrive
Genie 4 is the first DeepMind world model with native audio, including ambient sounds and specified audio elements. It can create interactive dialogue that adapts as you change the simulation.
## Pricing starts at one hundred dollars
Google will roll out Genie 4 via the Gemini API and AI Studio for developers. Consumers get access through AI Ultra plans starting at one hundred dollars per month.
## Access rolling out in phases
DeepMind is working with a small group of trusted testers and plans to expand access soon with no specific timeline yet. A waitlist is available for early access.
## Key takeaway

DeepMind unveiled Genie 4, an improved world model generating realistic simulations with physics, audio and interactive dialogue, launching via paid API access.
