Automate manual tasks and workflows using AI-driven Workflow Automation
Request a demo Get Started


Retrieval Augmented Generation, or RAG, is a mechanism that helps large language models (LLMs) like GPT become more useful and knowledgeable by pulling in information from a store of useful data, much like fetching a book from a library. Here’s how retrieval augmented generation makes magic with simple AI workflows:

  • Knowledge Base (Input): Think of this as a big library full of useful stuff—FAQs, manuals, documents, etc. When a question pops up, this is where the system looks for answers.
  • Trigger/Query (Input): This is the starting point. Usually, it's a question or a request from a user that tells the system, “Hey, I need you to do something!”
  • Task/Action (Output): Once the system gets the trigger, it swings into action. If it’s a question, it digs up an answer. If it’s a request to do something, it gets that thing done.

Now, let’s break down the retrieval augmented generation mechanism into simple steps:

  1. Retrieval: First off, when a question or request comes in, RAG scours through the Knowledge Base to find relevant info.
  2. Augmentation: Next, it takes this info and mixes it up with the original question or request. This is like adding more detail to the basic request to make sure the system understands it fully.
  3. Generation: Lastly, with all this rich info at hand, it feeds it into a large language model which then crafts a well-informed response or performs the required action.

So, in a nutshell, RAG is like having a smart assistant that first looks up useful info, blends it with the question at hand, and then either gives out a well-rounded answer or performs a task as needed. This way, with RAG, your AI system isn’t just shooting in the dark; it has a solid base of information to work from, making it more reliable and helpful.

What problem do they solve?

Bridging the Knowledge Gap

Generative AI, powered by LLMs, is proficient at spawning text responses based on a colossal amount of data it was trained on. While this training enables the creation of readable and detailed text, the static nature of the training data is a critical limitation. The information within the model becomes outdated over time, and in a dynamic scenario like a corporate chatbot, the absence of real-time or organization-specific data can lead to incorrect or misleading responses. This scenario is detrimental as it undermines the user's trust in the technology, posing a significant challenge especially in customer-centric or mission-critical applications.

Retrieval Augmented Generation

Retrieval Augmented Generation comes to the rescue by melding the generative capabilities of LLMs with real-time, targeted information retrieval, without altering the underlying model. This fusion allows the AI system to provide responses that are not only contextually apt but also based on the most current data. For instance, in a sports league scenario, while an LLM could provide generic information about the sport or teams, RAG empowers the AI to deliver real-time updates about recent games or player injuries by accessing external data sources like databases, news feeds, or even the league's own data repositories.

Data that stays up-to-date

The essence of RAG lies in its ability to augment the LLM with fresh, domain-specific data. The continual updating of the knowledge repository in RAG is a cost-effective way to ensure the generative AI remains current. Moreover, it provides a layer of context that a generalized LLM lacks, thereby enhancing the quality of responses. The ability to identify, correct, or delete incorrect information within the RAG’s knowledge repository further adds to its appeal, ensuring a self-correcting mechanism for more accurate information retrieval.

Examples of RAG Workflows

In the evolving realm of artificial intelligence, Retrieval-Augmented Generation (RAG) is making a substantial impact across various business sectors by significantly enhancing the capabilities of Large Language Models (LLMs). Let us look at a few examples to get a sense of how RAG workflows automate tasks -

  3. Legal Research and Case Preparation:
    • Scenario: A law firm integrates RAG to expedite legal research and case preparation.
    • Workflow:
      • Retrieval: On input about a new case, it pulls up relevant legal precedents, statutes, and recent judgements.
      • Augmentation: It correlates this data with the case details.
      • Generation: The system drafts a preliminary case brief, significantly reducing the time attorneys spend on preliminary research.
  4. Customer Service Enhancement:
    • Scenario: A telecommunications company implements a RAG-augmented chatbot to handle customer queries regarding plan details, billing, and troubleshooting common issues.
    • Workflow:
      • Retrieval: On receiving a query about a specific plan's data allowance, the system references the latest plans and offers from its database.
      • Augmentation: It combines this retrieved information with the customer’s current plan details (from the customer profile) and the original query.
      • Generation: The system generates a tailored response, explaining the data allowance differences between the customer’s current plan and the queried plan.
  5. Inventory Management and Reordering:
    1. Scenario: An e-commerce company employs a RAG-augmented system to manage inventory and automatically reorder products when stock levels fall below a predetermined threshold.
    2. Workflow:
      1. Retrieval: When a product's stock reaches a low level, the system checks the sales history, seasonal demand fluctuations, and current market trends from its database.
      2. Augmentation: Combining the retrieved data with the product's reorder frequency, lead times, and supplier details, it determines the optimal quantity to reorder.
      3. Task Execution: The system then interfaces with the company's procurement software to automatically place a purchase order with the supplier, ensuring that the e-commerce platform never runs out of popular products.
  6. Employee Onboarding and IT Setup:
    1. Scenario: A multinational corporation uses a RAG-powered system to streamline the onboarding process for new employees, ensuring that all IT requirements are set up before the employee's first day.
    2. Workflow:
      1. Retrieval: Upon receiving details of a new hire, the system consults the HR database to determine the employee's role, department, and location.
      2. Augmentation: It correlates this information with the company's IT policies, determining the software, hardware, and access permissions the new employee will need.
      3. Task Execution: The system then communicates with the IT department's ticketing system, automatically generating tickets to set up a new workstation, install necessary software, and grant appropriate system access. This ensures that when the new employee starts, their workstation is ready, and they can immediately dive into their responsibilities.

These examples underscore the versatility and practical benefits of employing retrieval augmented generation in addressing complex, real-time business challenges across a myriad of domains.

How to build your own RAG Workflows?

Process of Building an RAG Workflow

The process of building a Retrieval Augmented Generation (RAG) workflow can be broken down into several key steps. These steps can be categorized into three main processes: ingestion, retrieval, and generation, as well as some additional preparation:

1. Preparation:
  • Knowledge Base Preparation: Prepare a data repository or a knowledge base by ingesting data from various sources - apps, documents, databases. This data should be formatted to allow efficient searchability, which basically means that this data should be formatted into a unified 'Document' object representation.
2. Ingestion Process:
  • Vector Database Setup: Utilize Vector Databases as knowledge bases, employing various indexing algorithms to organize high-dimensional vectors, enabling fast and robust querying ability.
    • Data Extraction: Extract data from these documents.
    • Data Chunking: Break down documents into chunks of data sections.
    • Data Embedding: Transform these chunks into embeddings using an embeddings model like the one provided by OpenAI.
  • Develop a mechanism to ingest your user query. This can be a user interface or an API-based workflow.
3. Retrieval Process:
  • Query Embedding: Get the data embedding for the user query.
  • Chunk Retrieval: Perform a hybrid search to find the most relevant stored chunks in the Vector Database based on the query embedding.
  • Content Pulling: Pull the most relevant content from your knowledge base into your prompt as context.
4. Generation Process:
  • Prompt Generation: Combine the retrieved information with the original query to form a prompt. Now, you can perform -
    • Response Generation: Send the combined prompt text to the LLM (Large Language Model) to generate a well-informed response.
    • Task Execution: Send the combined prompt text to your LLM data agent which will infer the correct task to perform based on your query and perform it. For example, you can create a Gmail data agent and then prompt it to "send promotional emails to recent Hubspot leads" and the data agent will -
        • fetch recent leads from Hubspot.
        • use your knowledge base to get relevant info regarding leads. Your knowledge base can ingest data from multiple data sources - LinkedIn, Lead Enrichment APIs, and so on.
        • curate personalized promotional emails for each lead.
        • send these emails using your email provider / email campaign manager.
5. Configuration and Optimization:
  • Customization: Customize the workflow to fit specific requirements, which might include adjusting the ingestion flow, such as preprocessing, chunking, and selecting the embedding model.
  • Optimization: Implement optimization strategies to improve the quality of retrieval and reduce the token count to process, which could lead to performance and cost optimization at scale.
