Generative AI vs Agentic AI: Complete Guide

Author: Narendra Mandadapu
Posted: May 28, 2025

Generative AI refers to artificial intelligence systems that can create new content - text, images, code, audio, video, or other media - based on patterns learned from training data. These systems produce original outputs by predicting and generating the most likely next elements in a sequence.

Core Workflow: Input → Process → Generate

Receives prompts or inputs
Processes information through learned patterns
Generates content as output
Typically single-turn interaction

Agentic AI

Agentic AI refers to AI systems that can act autonomously to achieve goals by planning, making decisions, and taking actions in an environment. These systems can break down complex objectives into steps, use tools, interact with external systems, and adapt their approach based on feedback.

Core Workflow: Think → Act → Observe (continuous cycle)

Think: Plans next action based on current state and goals
Act: Executes actions in the environment
Observe: Monitors results and feedback from actions
Repeats cycle until goals are achieved

Detailed Comparison Table
