The AI Integration Layer within SAP's AI Foundation architecture serves as the unified entry point for development, operations, and administration. According to SAP Business AI documentation, this layer facilitates seamless interaction between AI components, SAP applications, and external systems, providing a centralized interface for developers, operators, and administrators. It supports tasks such as model deployment, monitoring, and governance, ensuring consistency and efficiency across AI operations. The OS Interfaces Layer handles system-level interactions, the Peripheral & Data Layer manages data access, and the AI Kernel Layer focuses on core AI processing, none of which serve as the unified entry point. This layer is critical for enabling scalable and integrated AI solutions.
