## Definition
Agentic AI refers to artificial intelligence systems designed to act autonomously, make decisions, plan workflows, and execute tasks without constant human intervention. Unlike traditional models that only respond to queries, agentic systems use an agentic loop to perceive environments, reason over goals, use tools, and iterate to achieve outcomes.

## Architectural Mechanics & Deep Dive
Agentic AI shifts the paradigm from passive response generation to goal-directed execution. Instead of treating Large Language Models as simple text generators, agentic architectures embed them inside a loop (often referred to as an agentic loop or cognitive loop). This loop gives the AI system state memory, reasoning capability, access to external tools (such as search, databases, or terminal environments), and a self-reflection phase. When given a complex objective, the agent creates a task checklist, runs code or retrieves information, evaluates the outcome, and recursively corrects its mistakes until the target goal is met.

## Industry Applications & Real-World Use Cases
Autonomous workflows, coding agents, and RPA

## Frequently Asked Questions

### What is the difference between Agentic AI and standard LLMs?
Standard LLMs respond to individual prompts in a single turn. Agentic AI uses the LLM as a brain within a loop, allowing it to write code, test it, use web search, and correct errors recursively until the goal is achieved.

### How does Agentic AI interact with external tools?
Agentic AI uses tool calls or protocols like Model Context Protocol (MCP) to read databases, run local commands, edit files, or invoke APIs.
