Scenario

You’ve been saying “I’ll learn LangChain” since last quarter. Your GitHub starred tab is overflowing. Let’s stop procrastinating.

Skills You Will Use

• Python scripting
• Working with embeddings
• Retrieval systems
• GenAI workflows.

Tools & Platforms

• LangChain
• FAISS
• Python
• Streamlit (optional UI)
• Hugging Face (for embeddings)
• Google Colab (for setup)

Guided Steps

• [ ] Choose a PDF or small text dataset (e.g., product manual, internal policy doc).
• [ ] Use LangChain to chunk and embed the data.
• [ ] Load the vector store with FAISS.
• [ ] Prompt the model to answer questions using retrieved content.
