Start Your Generative AI Journey with Top 5 RAG Tools
What is Retrieval-Augmented Generation?
Retrieval-augmented generation(RAG) is a technique used to make the responses from AI models, like chatbots, more accurate and relevant. Here’s a simple explanation:
Imagine you have a smart assistant that can answer questions. This assistant has learned a lot from reading many books and articles, so it knows quite a bit. But sometimes, it might not have the most up-to-date or specific information because it only knows what it reads up to a certain point.
RAG helps this assistant by allowing it to look up information from a trusted source, like a database or a website before it answers your question. This way, even if the assistant didn’t originally learn about a specific topic, it can quickly find the right information and give you a more accurate and relevant answer.
So, instead of guessing or giving outdated answers, the assistant combines what it already knows with fresh, reliable information it retrieves on the spot. This makes the assistant much more useful, especially for answering specific or complex questions without needing to be retrained constantly.
In short, RAG improves AI responses by letting the AI look up additional information before giving you an answer, ensuring the information is accurate and up-to-date. Here are below the most powerful RAG tools those use to create RAG application.
What is the process of RAG?
The diagram outlines the steps involved in Retrieval-Augmented Generation (RAG), which enhances the responses generated by a Large Language Model (LLM) by incorporating external knowledge. Here are the steps broken down:
- Data Collection: Think of it as having a library of books and documents.
- Dividing the Content: Instead of searching through whole books, the system breaks them down into chapters or even paragraphs.
- Prompt + Context: When you ask a question, the system understands what you’re asking and what kind of information you need.
- LLM: The smart assistant that can talk to you. It uses both its knowledge and the library to find and present the best answer.
- Output: The final, polished answer that combines the assistant’s smarts and the specific information from the library.
This process ensures that the AI provides answers that are not only generated from its training but also enriched with specific, up-to-date information from external sources.
