NVIDIA Introduces γ‑World: Scalable Multi‑Agent Generative World Model
NVIDIA’s γ‑World is a generative world model that can simulate multiple agents simultaneously, using Simplex Rotary Agent Encoding for permutation‑symmetric control and Sparse Hub Attention to keep cross‑agent computation linear. The model produces real‑time, 24 FPS rollouts and can zero‑shot generalize from two‑player to four‑player scenarios, improving video fidelity and inter‑agent consistency.
