DeepMind's Genie 4 promises more realistic physics and humans — if you pay
Ars Technica AI · rss · 2026-10-28
Ars Technica covers Google DeepMind's Genie 4. Last year's Genie 3 sent gaming stocks tumbling; since then world models have become a major focus for AI labs. Genie 4 improves on Genie 3 in almost every way — more realistic physics and humans, aided by updated Gemini models. Google frames world models as a key element toward AGI: no pre-rendered environments or programmed interactivity, just real-time frame-by-frame generation of explorable experiences. Potential uses span infinite robot training environments and rapid creative prototyping — but you'll need to pay Google enough to actually get access.
