Agentic Workflows (vs Pipelines)

From Linear Steps to Autonomous AI Behavior

As LLMs become more powerful, we're moving from fixed pipelines (step-by-step flows) to more flexible, intelligent agents that can decide, adapt, and act on their own. This shift introduces a key distinction:

Agentic Workflows vs Traditional Pipelines

Let’s explore the difference.

🛠️ What Is a Pipeline?

A pipeline is a fixed sequence of steps where each one performs a defined task, usually in a straight line.

Example:

In a document Q&A app:

1. Load document

2. Chunk and embed it

3. Retrieve relevant chunks

4. Generate an answer using LLM

This works well when the flow is predictable — like an assembly line.

✅ Good for:

• RAG systems

• Data processing

• Structured, repeatable tasks

⚠️ Limitation:

• No flexibility — can't adjust based on situation or error

🤖 What Is an Agentic Workflow?

An agentic workflow uses one or more LLM-powered agents that can:

• Make decisions

• Use tools

• Plan multiple steps

• Loop, retry, or change paths dynamically

Think of it as a thinking assistant, not just a flow of tasks.

Example:

In a research assistant:

1. Read user’s goal

2. Search web or documents

3. Summarize results

4. Ask clarifying questions

5. Compose a final report (If info is missing, loop back and try a new strategy)

✅ Good for:

• Autonomous research

• Multistep tasks

• Dynamic user goals

• AI copilots and multi-agent systems
