NVIDIA Gamma-World scales multi-agent video generation to four players.

NVIDIA researchers introduced Gamma-World, a generative multi-agent world model using Simplex Rotary Agent Encoding and Sparse Hub Attention to enable real-time interactive video generation with multiple controllable agents at 24 FPS, generalizing from two to four players without retraining. Commerce platforms building multiplayer simulations, virtual showrooms, or interactive product demonstrations can now generate consistent, action-responsive environments with multiple participants at scale, reducing computational overhead from quadratic to linear attention complexity.
