Researchers in China have introduced GameGen-X, an innovative diffusion transformer model designed specifically for real-time generation and interactive control of open-world video games. This model, created with the assistance of OpenAI's GPT-4o, represents a significant advancement in generative gaming technology. GameGen-X allows users to control characters, change weather conditions, and alter the time within the game environment without any predefined gaming logic. This leap forward is facilitated by the largest dataset for open-world game video generation and control.
