Longer-form pieces on the model, the prompts, and the honest limits.
Using Genie 4 for Game Prototyping Before You Write Engine Code
How to use a world model in early game design: testing level pacing, camera behaviour, and mechanic feel before committing engineering time — plus the cases where it will mislead you.
Genie 4 for Robotics and Agent Training — What It Changes
Why Google DeepMind leads with robotics when describing Genie 4: causal event simulation, procedural behaviour, and agent-in-the-loop experiments, plus the validation work you still have to do.
Genie 4 Limitations — What Breaks, and How to Plan Around It
An honest account of Genie 4's documented limitations: drift, complex physics, audio accuracy, legible text, spatial precision, and consistency — with practical mitigations for each.
Genie 4 Prompt Guide — Writing Prompts for a World Model
How to write prompts for Genie 4: the four elements that matter, templates you can copy, and the six mistakes that cost the most consistency in a generated world.
Genie 4 vs Genie 3 — What Actually Changed, and What Did Not
A capability-by-capability comparison of Genie 4 and Genie 3, including the specifications Google has not published for Genie 4 and why you should not assume Genie 3's numbers apply.
What Is Genie 4? A Complete Guide to DeepMind's World Model
Genie 4 is Google DeepMind's real-time multimodal world model. This guide covers what it is, how the Gemini-based architecture works, what it can and cannot do, and why world models differ from video generators.
