DeepMind launches Genie 4, a world model with more realistic physics and human behavior

Google DeepMind has unveiled its new world‑model, Genie 4, which builds on the earlier Genie 3 by incorporating the updated Gemini language models to deliver more accurate physics simulations and lifelike human interactions. The model can generate a virtual environment in real time without pre‑rendering or hand‑coded elements, allowing users to specify desired scenarios and receive frame‑by‑frame output. DeepMind says this capability can provide infinite training environments for physical robots and enable rapid prototyping in creative fields. The release follows the industry reaction to Genie 3, which caused a sharp drop in gaming stocks when it was first revealed.
