Learn LangChain and Gen AI by Building 6 Projects

Learning LangChain empowers you to seamlessly integrate advanced language models like GPT-4 into diverse applications, unlocking capabilities in natural language processing and AI-driven applications.

We just published a full course on the freeCodeCamp.org YouTube channel that will teach you how to build six end-to-end projects using LangChain and a variety of LLMs. Krish Naik created this course. He is a popular instructor with over 800,000 subscribers on his YouTube channel.

In this course you will learn to use LangChain with GPT-4, Google Gemini Pro, and Llama 2, creating a suite of practical, real-world applications.

Core Technologies

  1. LangChain: This tool helps integrate various Large Language Models (LLMs) like OpenAI’s GPT-3.5 and GPT-4 with external data sources. It opens up a world where the processing of natural language goes beyond pre-fed data, allowing for more dynamic and contextually aware applications.
  2. GPT-4: This is the latest LLM from OpenAI. This course will demonstrate how GPT-4’s advanced capabilities can be harnessed in tandem with LangChain for creating sophisticated Natural Language Processing (NLP) applications.
  3. Google Gemini Pro: This component provides an in-depth look at Google’s powerful tool for language understanding and processing, demonstrating its application in real-time scenarios.
  4. Llama 2: Focused on blog generation and other content creation, Llama 2 represents the forefront of language model technology. It offers insights into how these models can be utilized for creative and efficient content generation.
