This paper presents a significant advancement in fusion research by utilizing transformer-based AI models to create a fast and accurate surrogate for computationally expensive plasma edge simulations. This allows for rapid scenario exploration and control-oriented studies, potentially leading to real-time applications in fusion devices. The ability to predict long-horizon dynamics and reproduce key features like high-radiation region movement is crucial for designing plasma-facing components and optimizing fusion reactor performance. The speedup compared to traditional methods is a major advantage.
