With this chapter, we embark the hands-on section of this book with a first concrete implementation of LLM-powered applications. Throughout this chapter, we will cover a step by step implementation of a conversational application, using LangChain and its components. The main steps will be the following:
- Configuring the schema of a simple chatbot
- Adding the memory component
- Adding non-parametric knowledge
- Adding tools and make the chatbot “agentic”
By the end of this chapter, you will be able to set up your own conversational application project with just few lines of code.
