In a large retail enterprise, our GPU cloud platform was used to develop an intelligent customer service system based on deep learning technology that can process customers' natural language queries. Through our high-performance computing resources, the team can quickly train large-scale language models, enabling the system to have real-time responsiveness. This intelligent customer service system not only improves customer satisfaction, but also significantly reduces the workload of manual customer service, achieving a reduction in operating costs and an improvement in service efficiency.
