摘要
Artificial Intelligence Generated Content (AIGC) has gained significant popularity for creating diverse content. However, current AIGC models primarily focus on content quality within a centralized framework, resulting in a high service delay and negative user experiences. The workload of an AIGC task is determined by model complexity and multi-layered encoder architectures, posing significant challenges for its modeling, deployment, and scheduling within resource-constrained edge networks. We model an offloading problem among edges for providing real AIGC services and propose \textbf{LAD-TS}, a novel Latent Action Diffusion-based Task Scheduling method that orchestrates multiple edge servers for expedited AIGC services by leveraging the diffusion model's conditional guidance capability and the reinforcement learning's environment interaction ability. We first design an innovative Latent Action Diffusion Network (LADN) model based on traditional diffusion models. We then incorporate the LADN model into deep reinforcement learning, forming an effective LAD-TS method for task scheduling in distributed edge networks. Meanwhile, we design a latent action diffusion strategy to achieve near-optimal decisions quickly by utilizing historical action probabilities instead of Gaussian noise. Furthermore, we implement a refined AIGC model and develop \textbf{DEdgeAI}, a prototype edge system with the refined AIGC model deployment to evaluate our LAD-TS method. DEdgeAI provides a real AIGC service for users, demonstrating up to $7.36\%-18.11\%$ and $34.07\%-94.96\%$ shorter service delays than the state-of-the-art methods and representative commercial platforms, respectively. We release our open-source code at https://github.com/ChangfuXu/DEdgeAI/
