# LLMOps guide

Welcome to the ZenML LLMOps Guide, where we dive into the exciting world of Large Language Models (LLMs) and how to integrate them seamlessly into your MLOps pipelines using ZenML. This guide is designed for ML practitioners and MLOps engineers looking to harness the potential of LLMs while maintaining the robustness and scalability of their workflows.

To follow along with the examples and tutorials in this guide, ensure you have a Python environment set up with ZenML installed. Familiarity with the concepts covered in the [Starter Guide](https://docs.zenml.io/user-guides/starter-guide) and [Production Guide](https://docs.zenml.io/user-guides/production-guide) is recommended.

We'll showcase a specific application over the course of this LLM guide, showing how you can work from a simple RAG pipeline to a more complex setup that involves finetuning embeddings, reranking retrieved documents, and even finetuning the LLM itself. We'll do this all for a use case relevant to ZenML: a question answering system that can provide answers to common questions about ZenML. This will help you understand how to apply the concepts covered in this guide to your own projects.

By the end of this guide, you'll have a solid understanding of how to leverage LLMs in your MLOps workflows using ZenML, enabling you to build powerful, scalable, and maintainable LLM-powered applications. First up, let's take a look at a super simple implementation of the RAG paradigm to get started.
