What is Retrieval Augmented Generation (RAG)
Retrieval Augmented Generation (RAG) is a concept in the context of large language models (LLMs) that allows for more specific and relevant responses. LLMs are powerful but rely on general training data, which may not be domain-specific or up-to-date. RAG addresses this by constraining the LLM to only consider information from specific data sources provided in the prompt. This ensures that the generated content is contextual, accurate, and relevant to the specific data sets.
How Retrieval Augmented Generation Works
Retrieval Augmented Generation involves three steps: 1) Getting data and storing it in a searchable database, 2) Augmenting the prompt with context from the stored data sources, and 3) Sending the augmented prompt to the LLM and retrieving the generated response. By combining the relevant context with the user's query, RAG ensures that the LLM system focuses on specific information and provides more accurate and tailored responses.
Benefits and Challenges of Retrieval Augmented Generation
Retrieval Augmented Generation offers several benefits, including the ability to provide contextually accurate and detailed responses based on the latest and most relevant data. RAG systems are adaptable and well-suited for domain-specific applications. Implementing RAG is also easier and faster compared to fine-tuning LLMs or relying solely on prompt engineering. However, challenges include the potential for hallucinations, as LLMs still have limitations and can generate incorrect responses. Careful prompt engineering and context management are necessary to reduce hallucinations and ensure reliable results.
It’s hard to have a conversation about AI these days without the topics of Generative AI and Large Language Models (LLMs) coming up. And, Large Language Models (LLMs) have been proving useful for a variety of things such as helping write text, write code, generate images, and help augment human workers. However, as people are using LLMs, they are demanding even greater accuracy and relevance to their specific industry and/or topic area.
