Build Chat Applications with OpenAI and LangChain

This comprehensive course dives into the rapidly growing LangChain Python library to help you develop engaging chatbot applications. You'll gain hands-on experience using OpenAI's API key to access their cutting-edge large language models (LLMs).

We'll explore how to leverage LangChain and its integrations to:

  • Create compelling prompts for optimal AI response and relevance.
  • Add memory to your chatbots for contextual conversations.
  • Incorporate external data to expand knowledge.
  • Link to third-party tools like search engines, code interpreters, Wikipedia, GitHub, and even Gmail.

Key Features & Integrations:

LangChain stands out with its ability to connect to diverse language models and load documents in various formats. You'll learn to select appropriate embedding models, store embeddings in vector stores, and build powerful RAG (Retrieval Augmented Generation) systems.

LangChain Expression Language (LCEL): Master the LCEL – crucial for building stateful and context-aware reasoning chatbots. These chatbots can remember past interactions, answer questions based on new data, and handle complex inquiries.

Retrieval Augmented Generation (RAG): We'll delve into RAG, both theoretically and practically. This technique empowers LLM applications to analyze and answer questions using information outside their original training data.

Project: Course Chatbot You'll culminate your learning by building a functional chatbot capable of answering student questions about courses from the 365 library.

Skills You'll Gain:

  • Integrate LLMs: Seamlessly integrate existing applications with powerful large language models.
  • OpenAI API: Connect to OpenAI's language models and embedding models using your OpenAI API key.
  • Prompt Engineering: Develop effective prompt engineering techniques for enhanced AI response quality.
  • RAG Implementation: Implement Retrieval Augmented Generation (RAG) to enrich your AI-driven products with a robust knowledge base.
  • LCEL Mastery: Become proficient in the LangChain Expression Language (LCEL) for building advanced applications.
  • Tool Integration: Connect external tools to your LLM-powered applications.
  • Agent Understanding: Understand the mechanics of agents and agent executors.
