Build Advanced RAG Applications with LangChain.js
The recent Hack Together: RAG Hack event showcased innovative developments in the realm of AI and Natural Language Processing. This global hackathon, running from September 3rd to 16th, 2024, focuses on the Retrieval Augmented Generation (RAG) technique. This approach enhances the accuracy and relevance of responses generated by language models.
What’s New in RAG Applications?
During the event, Glaucia Lemos and Yohan Lasorsa from Microsoft highlighted how LangChain.js is transforming the development of RAG applications. This tool enables developers to integrate large language models (LLMs) with their own data sources seamlessly.
“RAG allows developers to combine large language models with their own data sources, improving the accuracy and relevance of generated responses.”
Major Updates from the Live Session
A live session on September 4th featured a demonstration of a Serverless AI Chat application, called the Contoso Real Estate AI Chat. This chatbot allows users to inquire about properties for sale, showcasing the practical applications of RAG.
Participants learned how to build RAG applications using various programming languages, including Python, Java, and JavaScript/TypeScript. The event also introduced Azure AI services like AI Search and PostgreSQL, enriching the development experience.
How Does RAG Work?
The RAG process consists of two main components: retrieval and generation. First, a question is sent to the language model. The model’s retriever searches for relevant information in a knowledge base. Finally, the generator creates an answer based on the retrieved data.
“RAG combines retrieval and generation to provide accurate answers, making it a powerful tool for developers.”
What’s Important to Know
Developers participating in the hackathon can win prizes up to USD 500 in various categories. These include best overall application and best use of specific technologies like Azure SQL and PostgreSQL.
For those interested in exploring further, recordings of the live sessions are available online. Participants can also access the Contoso Real Estate AI Chat application on GitHub to create their own versions.
Join the hackathon and dive into the world of RAG applications with LangChain.js. This is an exciting opportunity to innovate and enhance the capabilities of AI-driven technologies.
