In the rapidly evolving landscape of artificial intelligence, Large Language Models (LLMs) and Generative AI (GenAI) have emerged as front-runners in shaping the next generation of intelligent applications, where human-like data generation is necessary. While their capabilities have shown transformative potential in centralized computing environments, there is a growing shift towards decentralized edge AI models, where computations are orchestrated closer to data sources to provide immediate insights, faster response times, and localized intelligence without the overhead of cloud communication. For latency-critical applications like autonomous vehicle driving, GenAI at the edge is vital, allowing vehicles to instantly generate and adapt driving strategies based on ever-changing road conditions and traffic patterns. In this paper, we propose a latency-aware service placement approach, designed for the seamless deployment of GenAI services on these cloudlets. We represent GenAI as a Direct Acyclic Graph, where GenAI operations represent the nodes and the dependencies between these operations represent the edges. We propose an Ant Colony Optimization approach that guides the placement of GenAI services at the edge based on capabilities of cloudlets and network conditions. Through experimental validation, we achieve notable GenAI performance at the edge with lower latency and efficient resource utilization. This advancement is expected to revolutionize and innovate in the field of GenAI, paving the way for more efficient and transformative applications at the edge.
