How to Build a Multi-Agent AI Pipeline with CrewAI and LangChain (Step-by-Step)

Short summary

A practical tutorial showing how to build production-ready AI agents using CrewAI and LangChain with Claude as the LLM backbone. It covers the conceptual difference between chatbots and agents (planning, tool use, multi-step execution) and provides working Python code for a two-agent research-and-writing crew. Also includes a LangChain-based alternative for developers who want more granular control over tool-calling agents.

• •Explains agents vs chatbots: agents plan, execute, observe, and adapt autonomously
• •Provides full CrewAI code for a researcher + writer agent crew using web search tools
• •Includes a LangChain alternative using Claude for tool-calling agents with more control
