RAG represents a blend of traditional language models with an innovative twist: it integrates information retrieval directly into the generation process. Think of it as having an AI that can look up information in a library of texts before responding, making it more knowledgeable and context-aware....
Use RAG when you need language output that is constrained to some area or knowledge base, when you want some degree of control over what the system outputs, when you don’t have time or resources to train or fine-tune a model, and when you want to take advantage of changes in foundatio...
In short, RAG provides timeliness, context, and accuracy grounded in evidence to generative AI, going beyond what the LLM itself can provide. Retrieval-Augmented Generation vs. Semantic Search RAG isn’t the only technique used to improve the accuracy of LLM-based generative AI. Another technique...
Combine the power of the latest LLMs with your unique enterprise knowledge. Botpress is a flexible and endlessly extendable AI chatbot platform. It allows users to build any type of AI agent or chatbot for any use case – and it offers the most advanced RAG system in the market. ...
So, What Is Retrieval-Augmented Generation (RAG)? Retrieval-augmented generationis a technique for enhancing the accuracy and reliability of generative AI models with information fetched from specific and relevant data sources. In other words, it fills a gap in how LLMs work. Under the hood, LL...
When RAG provides data to the LLM, it also comes with a link or citation to the resource used in question. This provides further context to a user and allows for some self-support they may need in the future. Also, it legitimizes the answers generated, as there is another source backing...
index.query("What is RAG?") Thus RAG addresses two problems with large language models: out-of-date training sets and reference documents that exceed the LLMs’ context windows. By combining retrieval of current information, vectorization, augmentation of the information using vector similarity searc...

This mechanism makes DPR particularly effective for complex queries that require a deep understanding of the context. Step 2: Once the relevant documents are retrieved, they are used to condition the response generation in the second step of the RAG process. This is done using a sequence-to-...
In the ever-evolving field of natural language processing (NLP), the quest for more intelligent, context-aware systems is ongoing. This is where retrieval-augmented generation (RAG) comes into the picture, addressing some of the limitations of traditional generative models. So, what drives the in...
