# Google DeepMind unveils Genie 4, a real-time world model with native audio, text steering and two-minute scenes

On Oct 27, 2026 Google DeepMind announced Genie 4, its first real-time world model that generates audio natively (ambient sound, music, character dialogue). Users steer a running simulation with text prompts; Gemini models plan and check multi-step events; scenes stay consistent for up to two minutes, double Genie 3. It is a research preview for trusted testers, coming to AI Ultra (Project Genie) and Gemini API early-access partners.

## Key facts
- Announced 2026-10-27 (DeepMind blog by Raia Hadsell, Diego Rivas and Hang Qi; launch posts by @GoogleDeepMind, 2.66M views, and Sundar Pichai, 1.46M views, on Oct 27)
- DeepMind: 'our first real-time world model to generate audio natively' (ambient sound, music, interactive dialogue with characters)
- Free-form real-time edits by text: weather, camera angle, adding people or objects; Gemini adapts prompts to the scene
- Built on the Gemini family: Gemini Omni anchors real-world appearance; Gemini 3.8 Flash acts as a guiding agent that plans steps and verifies frames; a Gemini Robotics experiment used Gemini 4 Argon to break tasks into steps simulated by Genie 4
- Scene consistency up to two minutes, double Genie 3's limit (TechCrunch); resolution and frame rate not stated
- Access: research preview for trusted testers; 'in the coming weeks' to Google AI Ultra subscribers in Project Genie and to early-access partners of the Gemini API and Google AI Studio (waitlist)
- Safety: internal safety evaluations before preview; all generated video and audio carry SynthID watermarks
- Known limits (DeepMind): detail and object permanence drift in long or heavily edited sessions; audio accuracy, legible text, spatial accuracy and long-term consistency still unsolved
- Demo includes an Apptronik Apollo humanoid playing checkers inside a Genie 4 simulation

## What happened

Google DeepMind released Genie 4 as a research preview on Oct 27, 2026, a little over a year after Genie 3. The blog post
(Raia Hadsell, Diego Rivas, Hang Qi) describes a world model that renders and sounds out an interactive scene in real time,
lets users change the running world with natural-language prompts, and uses Gemini models as a "director" that plans
multi-step events and checks the generated frames. DeepMind pitches it for gaming, interactive learning and robotics; a demo
shows an Apptronik Apollo humanoid playing checkers inside a simulation, and a Gemini Robotics experiment had Gemini 4 Argon
break a task into steps that Genie 4 then simulated.

TechCrunch reports scenes stay consistent for up to two minutes, double Genie 3's limit, and quotes Google research director
Tejas Kulkarni: "What we'll increasingly see in the future are these hybrid world models". Trusted testers mentioned film
prototyping and storyboarding as uses. Resolution, frame rate and pricing were not published.

## Why it matters

Genie 4 joins sound to playable world generation in one real-time model and ties it to Gemini's reasoning, the "hybrid"
design DeepMind says world models are moving to. Competitors are consolidating (AMD buying World Labs, Amazon reportedly in
talks for Decart, Runway's GWM Worlds 2 with audio), and world models are the main simulator pitch for training robots and
agents. Access is still limited to testers, so outside evaluations do not exist yet.
