4 Layers of Agentic AI Systems

Agentic AI systems are built on four distinct layers: LLMs as the foundation providing tokenization and inference capabilities, AI Agents that add autonomous behavior through tool usage and reasoning, Agentic Systems that coordinate multiple agents through communication protocols and orchestration frameworks, and Agentic Infrastructure that ensures production readiness with observability, security, and scalability features. Each layer builds upon the previous one to create robust, enterprise-ready AI systems.
