Foundational Generative AI models excel in crafting text responses derived from extensive language models (LLMs). These LLMs are trained using a vast array of data points, but the information utilized to produce these responses is restricted to the training data, which usually consists of a generic LLM. The data in the LLM might be outdated by weeks, months, or even years. Furthermore, it may not encompass specific details about a company's products or services when used in a corporate AI chatbot. This limitation can undermine trust in the technology among customers or employees, making it challenging to directly implement within the organization.
RAG allows to bypass the limitations of foundational LLMs by referencing an authoritative knowledge base outside of its training data sources before generating a response, hence optimizing the output. So how does it actually work?
RAG infuses the LLM with precise, up-to-date information without modifying the core architecture of the model. This infusion of targeted data ensures that the information is highly relevant to a specific organization or industry as well as guaranteeing that the AI's responses are rooted in the latest knowledge available. As a result, the model can deliver responses that are not only contextually accurate but also informed by the most current insights.
Create a knowledge library as a vector store
Organization’s intranet contains a diverse array of information assets, including structured data in databases, unstructured documents such as PDFs, blog posts, news articles, and transcripts from previous customer service interactions. This extensive and ever-evolving collection of data is converted into a standardized format and compiled into a centralized repository known as a knowledge library.
To facilitate the AI's understanding and utilization of this data, the contents of the knowledge library are transformed into numerical form through the application of a sophisticated algorithm known as an embedded language model. These numerical representations, or embeddings, are then stored within a vector database designed to be readily accessible to the generative AI, enabling it to draw upon a wealth of information.
Information retrieval
User query is converted into the same kind of vector and used for relevancy search. If an employee searches “What is a retrieval augmented generation framework” the system will retrieve this specific article alongside other technical documentations. All these documents will be returned because they are highly relevant to what the user has asked initially.
Augment the LLM prompt
The RAG model employs the technique of prompt engineering to integrate the user's question and the relevant retrieved document into a single prompt. This amalgamated prompt is then conveyed to the Large Language Model (LLM). By doing so, the enhanced prompt empowers the Large Language Model to generate precise responses to user queries.
