GAI tools utilize artificial intelligence to create various types of content, including text, images, audio, and video. Key features of GAI tools include the following:
RAG tools combine the power of Large Language Models (LLMs) with external knowledge sources. LLMs excel at understanding and generating human language. RAG enhances LLMs by allowing them to access and process information from a specific knowledge base (like documents, databases, or websites). Some key features of RAG tools include the following:
Agentic AI refers to autonomous artificial intelligence systems capable of achieving goals without constant human intervention. Key capabilities include:
An example is a self-driving car, which constantly analyzes traffic and makes real-time decisions for safe navigation. Agentic AI represents a shift from passive systems to proactive, autonomous ones.

Legal Research
GAI tools can offer benefits for legal research, but they come with significant limitations, such as potential inaccuracies, biases in the training data, and ethical concerns regarding confidentiality and proper attribution. In using GAI tools for legal research, legal professionals must critically assess GAI-generated information and maintain human oversight in their decision-making processes.
RAG tools in legal research offer significant advantages over stand-alone GAI tools by ensuring factual accuracy through the retrieval of real-world data from legal sources, thus minimizing errors and biases. They are specifically designed for the legal domain, enabling them to better understand terminology and provide tailored responses to legal queries. Additionally, RAG tools enhance transparency by offering source citations, allowing for easy verification and improved auditability of the information used.
The AI tools from Westlaw and Lexis are mainly classified as RAG tools. Although they incorporate some aspects of GAI—such as text generation—their primary focus is on retrieving and utilizing specific legal information from their own databases, which categorizes them primarily as RAG tools. Some key points include the following:
While Westlaw and Lexis are not fully "agentic" in the sense of being able to independently perform complex tasks, they do have some agentic qualities, such as proactively suggesting relevant information and automating certain tasks.
OpenAI's Deep Research (considered an agentic capability within ChatGPT) purports to allow users to conduct thorough research across various domains by leveraging an optimized model for web browsing and data analysis, generating detailed reports quickly, though it is currently limited to certain users and may have occasional accuracy issues.
GAI and RAG tools signify major technological progress. GAI tools boost human creativity and productivity, while RAG tools improve the reliability and informative value of AI systems.

Applications
AI encompasses various subfields, with GAI and agentic AI being two prominent types. GAI represents the creative aspect of AI, focusing on generating new content (like text, images, or music) by analyzing and mimicking patterns in existing data. This is evident in tools like ChatGPT and DALL-E.
On the other hand, agentic AI is designed to operate autonomously in order to achieve specific objectives. It is characterized by its ability to make decisions and respond dynamically to real-time information, as seen in applications like autonomous vehicles and robotic process automation. For example, a smart assistant managing your calendar showcases the capabilities of agentic AI.
While GAI typically works within predefined boundaries, agentic AI is more flexible and responsive. These two types of AI can complement one another effectively; for instance, in a virtual customer service agent, GAI can craft personalized responses while agentic AI manages the interaction in real-time.
