LangChain Mastery in 2025 | Full 5 Hour Course [LangChain v0.3]

James Briggs · Beginner ·✍️ Prompt Engineering ·1y ago
The Langchain library is a powerful tool for AI engineering, acting as the foundation of the broader LangChain-ecosystem (that is, LangGraph, LangSmith, LangServe, etc). In this course, you'll learn the fundamentals of building with LLMs and the essentials of LangChain — allowing you to build modern agentic systems and potentially move onto other components in the ecosystem such as LangGraph. Quick Links! 📌 All Course Material: https://aurelio.ai/course/langchain ⭐ Course Repo: https://github.com/aurelio-labs/langchain-course 🌟 Build Better Agents + RAG: https://platform.aurelio.ai (use "JBMARCH2025" coupon code for $20 free credits) This course includes 10 chapters, those are: 1️⃣ When to Use LangChain (https://www.aurelio.ai/learn/langchain-when-to-use) Guidelines for when we should use LangChain and what problems the framework does and does not solve. 2️⃣ Getting Started with LangChain (https://www.aurelio.ai/learn/langchain-intro) LangChain is one of the most popular open source libraries for AI Engineers. Here we will introduce the library. 3️⃣ AI Observability with LangSmith (https://www.aurelio.ai/learn/langsmith-intro) An introduction to LangSmith, an observability service for the LangChain-ecosystem. 4️⃣ Prompt Templating and Techniques in LangChain (https://www.aurelio.ai/learn/langchain-prompts) Prompting is a critical part of building AI software. Here we'll learn general prompting techniques and specific LangChain tooling for prompting. 5️⃣ Conversational Memory in LangChain (https://www.aurelio.ai/learn/langchain-conversational-memory) Exploring the various types of conversational memory and best practices for implementing them in LangChain v0.3 and beyond. 6️⃣ Introduction to LangChain Agents (https://www.aurelio.ai/learn/langchain-agents-intro) An introduction to LangChain's agents in v0.3 and up using both traditional and LCEL syntax. 7️⃣ LangChain Agent Executor Deep Dive (https://www.aurelio.ai/learn/langchain-agent-executor) A deep dive into
