What You'll Learn

From First Chain to Production Agent

This course takes you from LangChain fundamentals through advanced multi-agent orchestration, full observability, guardrails, multimodal AI, and enterprise deployment — with every concept backed by working code.

🔗
LangChain & LCEL
Chains, prompts, memory, tools and the Expression Language that ties it all together.
🗂️
RAG Pipelines
Hybrid retrieval, re-ranking, parent-document retrievers, and RAGAS evaluation.
🕸️
LangGraph Agents
Stateful graphs, checkpointing, human-in-the-loop, and multi-agent coordination.
🧩
Orchestration Patterns
Supervisor, plan-and-execute, reflection, map-reduce, debate, and swarm patterns.
🛡️
Guardrails & Safety
Input/output validation, PII detection, NeMo Guardrails, and Guardrails AI.
🔭
Full Observability
LangSmith tracing & eval plus Langfuse open-source monitoring for every call.
🌊
Streaming
Token-level SSE and WebSocket streaming from LangGraph to browser UIs.
🖼️
Multimodal AI
Vision, audio transcription, document intelligence, and multimodal RAG.

How It Works

Sequential Unlock System

  1. Read the module content
    Each module contains conceptual explanations, architecture diagrams, annotated code examples, and common pitfall callouts.
  2. Run the code examples
    Copy any snippet using the ⎘ Copy button, paste it into your environment, and experiment with modifications.
  3. Pass the knowledge check
    Score 80% or higher on the multiple-choice quiz at the end of each module. You can retry as many times as you need.
  4. Unlock the next module
    Passing the quiz immediately unlocks the next module and records your progress in the browser.
  5. Complete the Capstone
    Build a full enterprise AI application in Module 16 and earn your completion certificate.
