As generative AI is increasingly applied to business and services provided, what considerations should be made for the infrastructure that supports it? And what exactly is optimal infrastructure? Regarding infrastructure strategies to support "AI inference," which is becoming increasingly important as generative AI is increasingly implemented in society, OPTAGE, which operates an AI inference connectivity data center business, will explain the trends in the use of generative AI and GPU cloud, domestic and international case studies, and the importance of infrastructure for implementation. Generative AI not only learns, but also generates large amounts of inference processing in real time, so in addition to high-performance computing resources, low-latency, stable network connections are essential. This presentation will clearly explain the role and necessity of "AI inference connectivity data centers" located near communication hubs in urban areas.
