Retrieval-Augmented Generation (RAG) is a technique that combines the strengths of large language models (LLMs) with external data retrieval to improve the quality and relevance of generated responses.
The technique allows LLMs to acquire and analyze data from other available outside sources, particularly helpful in cases where the question is either complex, specific, or based on a given timeframe.
RAG is evolving, but Traditional RAG Architectures still face several challenges, including summarization, document comparison, structured data analysis, and handling queries with several parts.
Agentic RAG is the next evolution and uses intelligent agents to answer complicated questions that require careful planning, multi-step reasoning, and the integration of external tools.
Three primary Agentic strategies include routers, query transformations, and sub-question query engines.
Agentic RAG and LLMaIndex is a highly demanded backbone by companies willing to leverage AI for enhanced data-driven decision-making.
Key components of Agentic RAG implementation include tool use and routing, long-term context retention, subquestion engines for planning, reflection and error correction, and complex agentic reasoning.
Agentic RAG represents a shift in information processing by introducing more intelligence into the agents themselves for achieving a robust and accurate result.
By being generative and intelligent, these models and Agentic RAGs are on a quest to a higher efficiency as more data is being added to the pipelines.
