The advancement of RAG technology marks a turning point where AI transcends being a simple tool to becoming a truly intelligent partner. It is time to pay close attention to how RAG technology will reshape our daily lives and business landscapes in the future.

Agentic and Graph RAG: Expanding AI’s Thinking and Connectivity

The era where AI transcends simple information retrieval to independently think and plan has arrived. At the heart of this revolution are Agentic RAG and Graph RAG technologies. These groundbreaking RAG methods elevate AI’s capabilities, unlocking new possibilities for solving complex problems and advancing specialized research fields.

Agentic RAG: Enhancing AI’s Thought and Planning Abilities

Agentic RAG breaks through the limitations of traditional RAG technology by endowing AI with human-like reasoning and planning skills. Its core lies in breaking down complex questions into multiple steps and systematically gathering the necessary information at each stage.

For example, when faced with a complex question like, "What is the impact of artificial intelligence on financial markets and its outlook for the next five years?" Agentic RAG approaches it as follows:

1. Decomposing the question into detailed components (current AI impact on financial markets, five-year forecast, etc.)
2. Identifying information needs for each component (latest financial technology trends, economic forecast reports, etc.)
3. Collecting information via web searches, professional databases, API calls, and more
4. Synthesizing the gathered data into a logical and insightful answer

This approach is especially valuable in areas that require complex decision-making such as market trend analysis, investment strategy formulation, and policy making.

Graph RAG: Revolutionizing Specialized Research through Conceptual Connectivity

Graph RAG utilizes knowledge graphs to comprehend and represent the intricate relationships between concepts. This technology is driving groundbreaking advances in fields where diverse concepts are deeply interconnected, such as medicine, biology, and social sciences.

Graph RAG operates by:

1. Representing core concepts of a given topic as nodes
2. Connecting these concepts with edges to depict relationships
3. Leveraging the graph structure to grasp not only direct but also indirect correlations
4. Exploring the graph to gather and integrate information relevant to complex queries

For instance, in cancer research, Graph RAG can link concepts like ‘gene mutations,’ ‘protein interactions,’ ‘metabolic pathways,’ and ‘clinical symptoms’ to provide crucial insights for developing new treatments.

The Synergy of Agentic RAG and Graph RAG

Combining these two technologies takes AI systems to the next level. Agentic RAG’s systematic problem-solving approach melds with Graph RAG’s deep understanding of conceptual relationships, enabling results that can surpass human experts in complex interdisciplinary research and innovative product development.

For example, in drug discovery, this integrated RAG system might work as follows:

1. Agentic RAG breaks down the drug development process into stages (target identification, compound screening, toxicity evaluation, etc.)
2. Graph RAG analyzes the relationships among biological pathways, chemical structures, side effects, and more at each stage through graph analysis
3. Integrated analysis synthesizes results from both systems to propose the most promising drug candidates

The advancement of these sophisticated RAG technologies signifies AI’s evolution from a mere tool to a creative and strategic partner. Looking ahead, Agentic RAG and Graph RAG are poised to drive innovation across scientific research, business strategies, policy making, and beyond.

Multimodal RAG and Adaptive RAG: The Evolving Senses and Adaptability of AI

Multimodal RAG, which understands not only text but also images, audio, and video, and Adaptive RAG, which changes information retrieval methods according to user context! How far can the new possibilities created by these AI advancements go? In 2025, RAG technology has appeared before us in even more diverse and flexible forms.

Multimodal RAG: Awakening AI’s Five Senses

Multimodal RAG integrates visual and auditory elements into traditionally text-centered AI models, bringing the technology closer to human sensory perception. Now, AI can “see” and comprehend complex charts and diagrams, as well as “hear” and analyze voice data.

For instance, in finance, it can analyze complicated market trend graphs to offer immediate investment advice. In healthcare, it assists doctors by reviewing X-rays or MRI scans. This goes beyond mere image recognition—it's the result of advanced RAG systems that holistically analyze visual information alongside relevant medical literature.

Adaptive RAG: AI That Evolves According to the Situation

Adaptive RAG is an intelligent system that continuously learns and evolves through interaction with users. It dynamically adjusts its optimal information retrieval strategy by considering users’ question patterns, interests, and even emotional states.

A concrete example is a company’s customer service chatbot. It may start with simple keyword-based searches, but as questions become more complex, it automatically switches to semantic vector-based searches. Moreover, by detecting customer emotions, it can generate empathetic responses or accurately determine when to connect users with experts.

The Synergy of RAG: Combining Multimodal and Adaptive Technologies

The combination of Multimodal RAG and Adaptive RAG brings explosive improvements to AI systems. For example, on an e-commerce platform, AI can recommend similar products based on photos a customer takes and adjust the recommendation algorithms in real time according to the customer’s responses. This marks the birth of an advanced AI shopping assistant that goes beyond simple image matching to deeply understand customers’ preferences and purchasing patterns.

Challenges and Opportunities for the Future

The advancement of RAG technology means AI now possesses more human-like understanding and communication abilities. However, it also raises new challenges. Handling multimodal data requires greater computing power, and considerations regarding privacy protection and ethical use become even more critical.

Nevertheless, Multimodal RAG and Adaptive RAG are opening new horizons for AI. These technologies offer innovative applications across industries such as education, healthcare, and entertainment, making our daily lives smarter and more convenient.
