Enterprises have run into instances where RAG fails to deliver the expected results, prompting the development of agentic RAG, which incorporates AI agents into the pipeline.
AI agents with memory and reasoning capabilities enable agentic RAG to retrieve data from multiple knowledge sources, going beyond fetching information from just one knowledge source.
Agentic RAG can improve downstream LLM applications by enabling them to produce more accurate and validated responses to complex user queries.
There are two main ways to set up agentic RAG pipelines: incorporating a single agent system; and setting up multi-agent systems with a series of specialized agents that work across their respective sources to retrieve data.
Agentic RAG is still new and can run into occasional issues, including latencies stemming from multi-step processing and unreliability.
The agentic RAG pipeline could be expensive as the more requests the LLM agent makes, the higher the computational costs.
Agentic architectures are critical for the next wave of AI applications that can 'do' tasks rather than just retrieve information.
Enterprises should explore additional capabilities such as agentic AI and Generative Feedback Loops as they continue to level up their RAG applications.
The approach expands the knowledge base powering downstream LLM applications, enabling them to produce more accurate, grounded, and validated responses to complex user queries.
DSPy, LangChain, CrewAI, LlamaIndex, and Letta simplify building agentic RAG systems by plugging pre-built templates together.
