Deploy a Chatbot and RAG Pipeline for AI Inferencing on LKE

Tue, 11 Feb 2025 00:00:00 +0000

Overview

LLMs (Large Language Models) are increasingly used to power chatbots or other knowledge assistants. While these models are pre-trained on vast swaths of information, they are not trained on your own private data or knowledge base. To overcome this, you need to provide this data to the LLM (a process called context augmentation). This tutorial showcases a particular method of context augmentation called Retrieval-Augmented Generation (RAG), which indexes your data and attaches relevant data as context when users sends the LLM queries.
