Building AI applications with LangChain | Python Lang Chain

Description

Python Langchain is an open source framework for easily creating AI applications in python programming language. Langchain uses the pipe techniques to create a chain where output of one AI application is taken as the input to another AI application. The video depicts how to create a chain using LangChain and we can use multiple different LLM for the same. For demonstration purposes in this video, I'm using the open source GPT OSS model with Ollama which will be running in my own PC Timecodes 00:00 What is Python LangChain 00:24 What is the meaning of Chain in LangChain 01:39 Prerequisite for creating LangChain AI applications 02:33 AI application Problem statement - Sentiment and decision making 03:39 Creating Langchain Prompt and using LLM 04:27 Creating a simple LangChain Chain of Sequence 05:17 Invoking the Langchain based AI application 06:24 Creating second chain based on LangChain 08:08 Combining multiple constructs to create a longer chain #langchain #python #programming #theoryofcode #thetheoryofcode
