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:
Load document
Chunk and embed it
Retrieve relevant chunks
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:
Read user’s goal
Search web or documents
Summarize results
Ask clarifying questions
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
🧠 Key Differences
Flow Structure
Linear
Dynamic and adaptive
Intelligence
Predefined rules
LLM-powered reasoning and planning
Tool Use
Manual integration
Agents decide which tools to use
Flexibility
Low
High
Retry/Error Handling
Limited
Built-in reflection and retry logic
Examples
RAG, ETL, summarization flow
AutoGen, LangGraph, CrewAI, ReAct agents
🚀 Platforms for Agentic Workflows
LangGraph
Visual multi-agent graphs
AutoGen
Multi-agent chat architecture
CrewAI
Role-based task agents
LangChain Agents
Tool-calling agents
OpenAI Function Calling + Memory
Basic agent loop
🧠 Summary
Pipelines = Simple, step-by-step, no thinking
Agentic workflows = Smart, adaptive, decision-making AI
Agentic systems are key to autonomous assistants, AI copilots, and complex GenAI apps
