20 technical concepts behind modern AI agents
goyalshaliniuk · x · 2026-07-20
A visual guide breaks down 20 core concepts behind modern AI agents, from reasoning and planning to memory, retrieval, tool use, orchestration, observability, and deployment.
It frames agent building as much more than prompting:
- reasoning patterns like CoT, ReAct, and plan-and-execute
- tool use, function calling, and dynamic tool selection
- RAG, embeddings, short- and long-term memory
- multi-agent collaboration, self-reflection, state management, retries, logging, HITL, and deployment
The main takeaway is that production-ready agents depend on a full technical stack, not just a clever prompt.
