LangChain for LLM Application Development

Companion to the AI Agents in LangGraph course — this one covers the LangChain layer underneath: prompts, chains, output parsers, memory primitives, document loaders. Free, fast, and the right next step if you finished the prompt engineering course and want to compose multi-step LLM workflows. Limitation: LangChain has moved fast; some helper APIs shown have been renamed or replaced with LangChain Expression Language. Patterns are still correct; idioms have aged.

Introduction to LangGraph (LangChain Academy)

The official deeper-dive into LangGraph from LangChain Academy. Where the DeepLearning.AI short covers basics in 90 minutes, this one goes 6-8 hours into state, persistence, human-in-the-loop, streaming, and the LangGraph Cloud deployment story. Free, taught by LangChain engineering. The canonical follow-up after the DL.AI short course if you're committing to LangGraph for production.

  • +Right level of abstraction — above raw API calls, below full agents
  • +Pairs naturally with the LangGraph short course
Cons
  • −Some shown APIs have been renamed since release (LCEL is the new way)
  • −No coverage of LangSmith / evaluation — that's a separate course
Introduction to LangGraph (LangChain Academy)
Pros
  • +Official deep-dive from LangChain Academy
  • +Free, 6-8 hours of structured content
  • +Covers production patterns (persistence, HITL, streaming, LangGraph Cloud)
Cons
  • −LangGraph-only — no comparison to crewAI / AutoGen alternatives
  • −Pre-reqs: comfortable with LangChain basics

Which course is for whom?

LangChain for LLM Application Development
Best for
  • · Engineers building structured LLM apps but not yet full agents
  • · Anyone evaluating LangChain vs LlamaIndex vs raw API calls
Not ideal for
  • · Beginners — assumes you understand LLM API calls
  • · People who want production-ops focus (evals, tracing)
Introduction to LangGraph (LangChain Academy)
Best for
  • · Engineers committed to LangGraph for production agents
  • · Anyone past the DL.AI short course wanting production depth
Not ideal for
  • · Beginners evaluating frameworks — take the DL.AI short course first
