                         Difference between Gen AI | AI Agent | Agentic AI


Generative AI

Generative AI is a type of artificial intelligence that that creates new contents such as text, images, audio or video based on on pattern learnt from existing data.

AI Agent

AI Agent is a program that takes input, think and act to complete a task using tool, memory and knowledge. It is autonomous but narrow. It is task specific and does not span multiple or evolving goals. 

Agentic AI

Agentic AI is a system where one or more AI agents work autonomously, often over long task, making decisions, using tools and even other agent to reach the goal.
