Artificial Intelligence just keeps getting, well, more intelligent. This progression in AI technology is reshaping what’s possible with its use. And alongside this evolution is the introduction of new AI-based solutions like RAG (Retrieval-Augmented Generation).

RAG isn’t the driving force behind AI’s increasing intelligence, but rather a powerful method that combines advanced AI with your data to enhance AI applications.

Without your company’s specific data, AI responses can be as generic as a horoscope. RAG changes that, grounding AI outputs in real-time, relevant information.

But, how? What does RAG even mean? And how can I use it in my business?

In this guide, we’ll cover:


Would you rather have someone implement RAG into your business on your behalf?

Check out our RAG as a Service offering where we get a RAG system up and running so you get a solution that taps into your data in real-time.

What is RAG and How Does It Work?

First, let’s clear up that acronym.

RAG stands for Retrieval-Augmented Generation. It improves the output of Large Language Models (LLMs) by combining its natural language processing capabilities with a search and retrieval system.

ℹ️ What is RAG?

Retrieval-Augmented Generation (RAG) is a technique that improves the responses of AI language models by combining them with a search system.

This search system looks through a large collection of documents to find relevant information. This collection can be based on your proprietary company data that an LLM would never have access to on its own. By using this company information, the AI can give more accurate and up-to-date answers, instead of relying only on what it already knows.

RAG is great to use when factual accuracy and current information are important.

By blending static knowledge with dynamic retrieval, it allows businesses and organizations to stay ahead, delivering precise insights based on the most recent data.

Think of a hospital being able to search a patient’s updated medical records and the most recent medical research to reach a diagnosis.

How RAG Operates 🤖

RAG works in two stages. First, it retrieves relevant information from a vast dataset or an external source. Then, it leverages a LLM (large language model) to craft responses that are both accurate and context-aware.

Key elements of RAG include vector databases, which store and retrieve data efficiently, and NLP models (like GPT) that generate natural language text.

The RAG Architecture diagram shows how user queries from interfaces like Slack,Teams, and your digital products interact with structured and unstructured data retrievers, pulling information from sources like Salesforce, SQL Server, SAP, and more. The Generator (LLM) processes the data to provide accurate, context-specific responses.

RAG vs LLM: What Exactly is the Difference?

Unlike traditional LLMs that generate responses solely from their training data, RAG pulls in relevant information from external sources, like databases or the web, to craft contextually accurate and up-to-date responses.

They exist in tandem. So it’s not a case of ‘one vs the other’, it’s ‘what is an LLM capable of and how can RAG make it more capable?’.

But wait, can’t we fine-tune an LLM to be trained on new data? You can and at HatchWorks we are huge champions of fine-tuning LLMs. We even had a webinar about it, you can watch here.

Fine-tuning is important to adapt your LLM to your specific domain, improve accuracy for specialized tasks, and customize specific output. But if it’s all you’re doing, your system won’t have access to your real-time data. Plus you will need to continuously fine tune it.

That’s why you should use both fine-tuning and RAG. With RAG, your LLM can search through an ever-changing database. This keeps your LLM capable of specialization and pulling from real-time information.

RAG makes AI more accurate and efficient. That accuracy and efficiency trickles down to your business operations, making your team more productive and your AI use cases more reliable.

Let’s look a little closer at how that works.

Enhanced Accuracy:

Traditional AI models often “hallucinate” or generate plausible-sounding but incorrect information.

RAG minimizes this by pulling in verified facts from trusted databases or live web searches, ensuring the AI outputs are reliable and fact-based. When properly configured, RAG workflows allow the AI developer to set a confidence threshold, making sure that sensitive topics are treated with extra care for accuracy.

This is important in areas where precision is key, like healthcare, finance, and customer service, where incorrect information can lead to costly mistakes or lost trust.

Increased Efficiency:

Instead of spending hours manually searching for data or reviewing documents, RAG-powered LLMs can instantly provide relevant, contextual information tailored to specific queries. This requires the data be already prepared and ingested, of course – a major hurdle that our RAG as a Service solution aims to help with.

This speeds up workflows, reduces operational costs, and frees up your people to focus on more strategic tasks.

For businesses, this means being able to respond quickly to market changes, customer inquiries, or internal needs, all while maintaining a high standard of accuracy.

What to Be Wary of with RAG

RAG’s biggest drawback is that it’s resource-intensive and can incur significant computational and financial costs.

On top of that, integrating multiple models adds complexity, making systems harder to maintain and update over time.

You also need to consider data security if you’re integrating sensitive company or personal data into the LLM.

But don’t let any of that stop you from realizing the potential of RAG in your own business. With HatchWork’s RAG as a Service offering, you get a scalable solution that controls costs and grows with your needs.

The efficiency gains will quickly lead to a strong ROI, making your investment in RAG well worth it.

Plus, you won’t have to handle the complexity because we’ll handle it for you. Our RAG solutions are easy to maintain and we offer support to ensure smooth updates, so your team can focus on business goals, not the tech. Handover has never been smoother.

And finally, we take data security seriously. Our solutions are SOC2 Type 1 and HIPAA compliant, with strong encryption and secure access controls. That way an intern would have access to the same information as your CEO. We know your data is important and we ensure it is protected and meets industry standards.

Here’s what you need and a step-by-step guide to help you get started.

What You’ll Need: A Basic Checklist

Tools and software you may need include:

  • Vector Database: A vector database like Pinecone, Faiss, or Weaviate is essential for storing and retrieving unstructured data efficiently based on similarity.
  • Generative Model: A pre-trained NLP model such as GPT-4 (available from OpenAI or Hugging Face).
  • Retrieval Software: Use retrieval tools like ElasticSearch or Haystack to index and search your documents. Alternatively, equip your agent with capabilities to convert Text-to-SQL or hit an API for more robust querying capabilities.
  • Development Environment: Python is commonly used, so ensure you have a Python environment set up (Anaconda or a virtual environment can help).
  • APIs and Integrations: Access to OpenAI API or Hugging Face Transformers, and vector database APIs.

You also have infrastructure requirements, such as:

  • High-Performance Computing Resources: A server or cloud-based setup with sufficient CPU/GPU power and memory.
  • Storage: Adequate disk space for the vector database and the retrieval index.
  • Internet Connectivity: Stable and fast internet access, especially if using cloud-based tools or APIs.

The Steps You’ll Follow

We have a more in-depth look at this whole process in our article, How to Deploy an LLM Locally: More Control, Better Outputs. Below, we have a simpler version that focuses on the RAG element to serve Q&A against a company’s HR knowledge base.

Step 1: Set Up Your Environment

First, you need to build an environment where you can integrate RAG with an LLM.

Here’s what you’ll need:

  • An IDE like Visual Studio, along with version control (Git), to streamline your workflow.
  • LangChain for streamlined LLM integration, and libraries like torch, transformers, and faiss-cpu.
  • A vector database such as Epsilla for efficient embedding storage and retrieval, if dealing with unstructured data. In this example, we will be.
  • Pre-trained models (e.g., Mistral), and an inference engine like Llama CPP.


Here’s what you might need:

  • A powerful GPU.


You don’t need a GPU unless you’re doing fine-tuning or heavy tasks—just invoking an existing LLM doesn’t require it. If you are doing fine-tuning, you can use cloud services like AWS or Google Cloud for on-demand GPU access—no physical hardware necessary.

Step 2: Prepare Your Data

You need to identify and prep your data source—the one your RAG is retrieving from. This could be internal documents, public datasets, or external data from the internet.

It’s important to clean and preprocess your data for efficient indexing. Convert documents to a machine-readable format (like JSON or CSV).

Step 3: Set Up Your Vector Database

If dealing with unstructured data, you then need to choose and set up a vector database.

Use vector embeddings (from models like Sentence Transformers or OpenAI Embeddings) to transform your data into vectors and store them in your vector database for quick retrieval.

Step 4: Configure the Retrieval System

Install ElasticSearch or Haystack for document retrieval. These tools allow you to perform searches over your indexed data.

It will be helpful to set up indexes in your retrieval tool to enable quick searching and ranking of documents.

Alternatively, create tools within your Agent to access other retrieval tools. For example, set your agent up to use HTTP to communicate with APIs or SQL to query Databases.

Step 5: Integrate with the Generative Model

Now it’s time to connect your solution to the LLM of your choice to connect your generative model with the retrieval system.

These can be open-source LLMs like Llama or closed-source like GPT4. If you need help finding a model, check out the Hugging Face repository.

Finally, you’ll set up pipelines that retrieve relevant documents, and then pass them to the generative model to generate responses.

FAQs about RAG AI

What is RAG used for?

RAG (Retrieval-Augmented Generation) is used to generate more accurate, context-aware responses by combining retrieval of relevant data with natural language generation.

This approach allows AI systems to access and utilize up-to-date information, enhancing their ability to provide relevant and informed answers.

What is the difference between RAG and an LLM?

RAG uses real-time retrieval to enhance the output of generative models, while an LLM (Large Language Model) relies solely on pre-existing training data.

This means RAG can access and incorporate the most current information available in its knowledge base, whereas an LLM is limited to the data it was trained on, which may become outdated over time.

What is LoRa vs RAG?

LoRa (Low-Rank Adaptation) is a technique for fine-tuning models, while RAG focuses on dynamic data retrieval and generation.

LoRa is used to efficiently adapt pre-trained models to specific tasks or domains by updating a small number of parameters. RAG, on the other hand, augments model outputs with relevant information retrieved from an external knowledge base.

Is RAG better than fine-tuning?

To answer that question we need to clarify what fine-tuning is. Fine-tuning is the process of taking a pre-trained model and further training it on a specific dataset or for a particular task. This process adjusts the model’s parameters to better suit the target application, potentially improving its performance for that specific use case.

RAG is not necessarily “better” than fine-tuning but different; it’s more suitable for situations where real-time information could help you create more accurate outputs.

And it can be used in tandem to create a more capable, real-time solution that taps into your proprietary data.

Here are some key considerations and how it impacts your choice:

  • Flexibility: RAG allows for easy updates to the knowledge base without retraining the entire model, making it more adaptable to changing information.
  • Transparency: With RAG, it’s easier to trace the source of information used in generating responses.
  • Up-to-date information: RAG can access the most current data in its knowledge base, whereas fine-tuned models are limited to the data they were trained on.
  • Task-specific performance: Fine-tuning can lead to better performance on very specific tasks where the model needs to learn particular patterns or domain knowledge.

The choice between RAG and fine-tuning often depends on the specific use case, the nature of the data, and the desired balance between adaptability and task-specific optimization.
