\ud83d\udc49\ud83c\udffb Kick-start your freelance career in data: https://www.datalumina.io/data-freelancer This video is an introduction to the Python LangChain library. LangChain is a framework for developing applications powered by language models like OpenAI's GPT-3.5 and GPT-4. I will go over all the modules, provide examples, explain the quick start guide, and then show a demo of an intelligent assistant that can answer questions about any specific YouTube video. You can use LangChain to build your own intelligent systems, similar to Auto-GPT and BabyAGI. I believe there is an amazing opportunity right now for data scientists and AI engineers to become a front-runner using these tools. \ud83d\udd17 Links https://github.com/daveebbelaar/langchain-experiments https://python.langchain.com/ \u23f1\ufe0f Timestamps 00:00 Introduction 00:26 What is LangChain 01:19 Job opportunities 02:55 LangChain's Modules 03:47 Models 05:37 Prompts 06:43 Memory 08:21 Indexes 08:58 Chains 11:06 Agents 14:32 Use Case: YouTube Video Assistant 27:45 Why I am all in on this 28:15 What is Data Freelancer? \ud83d\udc4b\ud83c\udffb About Me Hey there, my name is @daveebbelaar and I work as a freelance data scientist and coach.
