Understanding Retrieval Augmented Generation (Rag)

TLDR Retrieval-Augmented Generation (RAG) offers a solution to the limitations of traditional language models by utilizing vector stores to retrieve and generate up-to-date information without the need for constant retraining. This approach allows for attribution of information sources and presents a promising alternative for handling user queries.

Key Insights

Understanding the Limitations of Traditional Language Models

Traditional language models face challenges in providing up-to-date information and source citations. They rely on pre-existing data and cannot dynamically update their knowledge, leading to outdated information upon deployment. This limitation creates time and cost constraints associated with constantly retraining models to stay relevant.

Implementing a Vector Store Approach

To address the limitations of traditional language models, a vector store approach is proposed. This approach involves storing embeddings of information and utilizing them for retrieval augmented generation. By connecting the model to a database for updating information, this approach aims to overcome the technical limitations presented by the models' lack of understanding large datasets of human language.

Advantages of Retrieval-Augmented Generation (RAG) Model

The RAG model offers the advantage of retrieving the latest information from a vector store and using it to generate responses, eliminating the need to retrain the model for every update. Additionally, it enables attribution of information sources, addressing the challenge of source citations. This approach provides a programmer's perspective by integrating vector stores to handle user queries and offer updated responses.
