AI Agents in LangGraph

via Coursera

4.7333 ratings at Coursera

Overview

LangChain, a popular open source framework for building LLM applications, recently introduced LangGraph. This extension allows developers to create highly controllable agents.

In this course you will learn to build an agent from scratch using Python and an LLM, and then you will rebuild it using LangGraph, learning about its components and how to combine them to build flow-based applications.

Additionally, you will learn about agentic search, which returns multiple answers in an agent-friendly format, enhancing the agent’s built-in knowledge. This course will show you how to use agentic search in your applications to provide better data for agents to enhance their output.

In detail:

1. Build an agent from scratch, and understand the division of tasks between the LLM and the code around the LLM.

2. Implement the agent you built using LangGraph.

3. Learn how agentic search retrieves multiple answers in a predictable format, unlike traditional search engines that return links.

4. Implement persistence in agents, enabling state management across multiple threads, conversation switching, and the ability to reload previous states.

5. Incorporate human-in-the-loop into agent systems.

6. Develop an agent for essay writing, replicating the workflow of a researcher working on this task.

Advantages and disadvantages

Advantages

  • Structured courses with graded quizzes, assignments and deadlines you can reset.
  • A shareable certificate from the university or company when you pay.
  • Financial aid is often approved for students in India (apply 15 days before you need it).
  • Andrew Ng and his team are among the clearest AI teachers anywhere.
  • Short courses are made with the companies building the tools (OpenAI, Google, AWS, Hugging Face).
  • From DeepLearning.AI, a well-regarded name.
  • Rated 4.7 out of 5 by 333 learners.
  • Self-paced: start any time.

Disadvantages

  • Paid after a 7-day free trial (Coursera Plus or per course).
  • Some courses can be audited for free, but graded work and certificates need payment.
  • Short courses are 1–2 hours: an introduction, not mastery.
  • Some notebooks need a paid Pro plan or your own API key.
  • Short (1 hour): an overview, not deep coverage.

Some points apply to every course of this kind; see how we rank.
