•

12/18/2024

Agentic AI is rapidly gaining traction as a transformative technology with the potential to revolutionize how we interact with and utilize artificial intelligence. Unlike traditional AI systems that passively respond to commands, agentic AI systems operate autonomously, making decisions and taking actions to achieve specific goals. This shift from passive to proactive AI has sparked considerable excitement and debate, with proponents touting its potential to automate complex tasks, optimize workflows, and enhance decision-making across various industries.

This report delves into the world of agentic AI, exploring its relationship with Retrieval Augmented Generation (RAG), examining the latest approaches, and analyzing its potential benefits and shortcomings. We'll also provide a comprehensive overview of companies and products offering agentic AI solutions, separating marketing hype from factual capabilities.

What is Agentic AI?

Agentic AI refers to advanced AI systems that can operate independently, much like a human employee. These systems go beyond simply responding to commands; they can understand context, set goals, and adapt their actions based on changing circumstances. Agentic AI systems are designed to pursue and achieve complex objectives with minimal human supervision. They can analyze situations, formulate strategies, and execute actions to achieve specific goals, all with minimal human intervention.

One of the key characteristics of agentic AI is its ability to dynamically adjust its execution strategy based on environmental changes and outcome assessment. This adaptability sets it apart from other forms of AI, such as Robotic Process Automation (RPA) or some generative AI systems, which typically follow pre-defined rules or rely on static models.

Agentic AI systems are not merely chatbots that provide responses based on single interactions. Instead, they use sophisticated reasoning and iterative planning to solve complex, multi-step problems. This allows them to handle more intricate tasks and workflows, understanding the bigger picture and breaking it down into smaller steps to achieve the desired outcome.

The potential benefits of agentic AI are significant. It can revolutionize customer interactions by providing personalized and responsive experiences at scale and speed. By leveraging sophisticated models, AI agents can infer customer intent, predict needs, and offer tailored solutions, all while operating 24/7 to ensure consistent and efficient support.

Furthermore, agentic AI systems can enhance human performance, productivity, and engagement rather than replacing human employees. By seamlessly integrating with existing systems and processes, agentic AI systems can form a powerful partnership with workforces, augmenting human capabilities and allowing employees to focus on higher-value tasks.

Agentic AI and Retrieval Augmented Generation (RAG)

Retrieval Augmented Generation (RAG) is a technique that enhances large language models (LLMs) by retrieving relevant information from external knowledge sources. This process allows LLMs to provide more accurate, contextually relevant, and grounded responses.

Agentic AI takes RAG a step further by incorporating AI agents into the RAG pipeline. These agents orchestrate the retrieval process, analyze data, refine responses iteratively, and adjust based on real-time feedback. This approach is particularly powerful in complex settings where dynamic data and multi-step reasoning are necessary.

Agentic RAG systems can continuously learn from their environment, refining their understanding with each data retrieval. This means that subsequent queries will likely yield better, more accurate results.

One of the key insights about agentic RAG is that it enables AI to act as a proactive partner, making real-time decisions independently. This marks a significant shift from passive to proactive AI, where systems can anticipate needs and offer solutions without explicit human intervention.

Core features of Agentic RAG include:

Intelligent Agents: Employs autonomous agents that analyze, reformulate queries, and refine responses as needed.
Multi-Step Reasoning: Capable of handling complex queries by dynamically adjusting responses.
Dynamic Workflow Adaptation: Leverages agents to adapt workflows based on context.
Tool Integration: Integrates tools like APIs, databases, and external functions to enhance capabilities.

Latest Approaches in Agentic AI

Self-Improving Agentic AI

Self-improvement, where an agent autonomously improves its own functioning, has intrigued the AI community for several decades. There are two main categories of self-improvement in agentic AI:

Narrow self-improvement: The agent improves its performance within a fixed operating environment or goal. For example, an LLM-based agent might monitor its performance and autonomously launch a fine-tuning loop to retrain its LLM on a new dataset when it detects performance deviations.
Broad self-improvement: The agent improves its performance across different environments or goals. This involves modifying its own architecture, learning algorithms, or reward functions.

One approach to self-improvement is reflection, a prompting technique where a language model analyzes and critiques its previous actions to identify areas for improvement. This process can also incorporate external data, such as insights from tool interactions, to provide a more informed and thorough reflection.

Self-improvement in agentic AI allows systems to continuously learn and adapt without constant human intervention. This is a key advantage of agentic AI, as it enables systems to become more effective and efficient over time without requiring ongoing manual updates or adjustments.

Another important aspect of self-improvement is the use of feedback loops. Agentic AI can use feedback loops where it actively seeks out new data to refine its models or decision-making.

Knowledge Representation in Agentic AI

Agentic AI and Vector Databases

Vector databases play a crucial role in agentic AI, particularly in RAG applications. They store vector embeddings of data, enabling efficient similarity search and retrieval of relevant information. In an agentic RAG system, an AI agent can evaluate a query's context and autonomously decide which vector database to query.
‍
Vector databases also enable agents to learn and adapt by storing and organizing vast amounts of information. This allows agents to become more versatile, understanding, and capable of handling complex tasks.
‍
Agentic RAG systems that utilize vector databases can incorporate various tools to enhance their capabilities, such as:

Querying a vector database: This is the most common tool, allowing the agent to retrieve relevant documents based on the query.
Query expansion: This tool improves the query by adding synonyms, correcting typos, or generating new queries based on the original one.
Extracting filters: This allows for narrowing down the results based on specific parameters.

Agentic AI and Graph Databases

Graph databases are useful for representing and analyzing complex relationships and networks in agentic AI systems. They can be used to store knowledge graphs, which provide a structured representation of knowledge that complements the capabilities of LLMs.

AI agents utilize memory and knowledge graphs for context and reasoning. This allows them to understand the relationships between different pieces of information and make more informed decisions.

Agentic AI and Ontologies

Ontologies provide a structured representation of knowledge that helps AI agents understand and reason about the world. They allow different AI systems to share and understand the same ideas and goals, making it easier for them to work together. Ontologies can also be updated as new information comes in or things change, helping AI agents stay adaptable and flexible.

The applications of ontologies in AI extend beyond simple knowledge representation. In healthcare, ontologies are helping AI systems understand the complex relationships between symptoms, diseases, and treatments, potentially revolutionizing diagnosis and patient care. In financial systems, ontologies enable AI to navigate the intricate web of global markets, regulations, and economic indicators, providing insights that can shape investment strategies.
