Large language models (LLMs) and AI agents are related — but they are not the same thing.
An LLM (Large Language Model) is an AI model trained on massive amounts of text to understand and generate human language.
Examples include:
LLMs primarily generate text, answer questions, summarize information, and assist with reasoning tasks.
An AI agent is a system that uses an LLM together with:
In simple terms:
You ask an AI model:
The model generates the content.
An AI agent might:
without direct human prompting at every step.
AI agents are gaining attention because they can potentially automate:
However, most AI agents still depend heavily on:

As AI tooling evolves, the distinction between models, workflows, and autonomous systems will likely become increasingly important for businesses and developers.
