Gen AI describes Large Language Models (LLMs) that are designed to create new content in the form of images, text, audio and more. This is the category of AI from which emerged ChatGPT, the model launched in November 2022 that brought Gen AI into the cultural mainstream. The initial model, GPT-2, was built on 1.5 billion parameters of data inputs. The subsequent model, GPT-3, was built on 175 billion parameters and GPT-4 was built on an astonishing 170 trillion parameters. But as staggering as this rapid growth was, the truth is that LLMs may have peaked in size. Indeed, OpenAI’s Sam Altman has indicated that “the age of giant AI models is already over” and that future versions will improve in different ways. Of course, the early-stage versions of these LLMs produced some results that amazed legal professionals of the possibilities and other results that alarmed them of the risks. But over the course of the past year, there has been tremendous innovation in LLM technology that is clearly driving Gen AI in the right direction. For one thing, the gap between private models (e.g., those from OpenAI, Google, Anthropic, Microsoft, etc.) and open source models (e.g., Llama, Falcon, Mistral, etc.) is narrowing. This is important because the open source ecosystem is driving a huge amount of innovation, fueled by easier access to the models themselves, easier availability of training data sets for everyone, lower costs, and the worldwide sharing of research to guide further development. Second, prompt engineering is now taking the form of traditional software engineering. In the early days of Gen AI, the science behind creating the back-end of the models was complex and few engineers had the ability to write the necessary code. We now have a variety of tools — such as LangChain and PromptFlow — that have turned this coding into an exercise in software engineering that is making it easier for developers to create user-friendly Gen AI tools. Third, LLMs’ ability to reason and to minimize “hallucination” has become quite impressive with the proper techniques. One of these techniques is known as Retrieval Augmented Generation (RAG). The RAG model is an LLM prompt cycle that accesses external information not included in its training data or model parameters to improve its responses to specific queries. ChatGPT, for example, relies solely on knowledge extracted from external sources on the open web (which are not grounded in fact). The most advanced of these models, such as our Lexis+ AI platform, can now deliver accurate and authoritative answers that are grounded in the closed universe of authoritative content — in our case, the most comprehensive collection of case law, statutes and regulations in the legal industry. “With the right model training, source materials and integration, RAG is poised to mitigate, if not resolve, some of generative AI’s most troubling issues,” reported Forbes. Another important dimension of tech innovation with LLMs is that more organizations are now deploying a “multi-model” approach to building their Gen AI solutions. This shift away from placing big bets on a single LLM is enabling developers to leverage different benefits from different models, creating their own solutions in a more flexible way that maximizes functionalities and minimizes risks. And an interesting development to keep your eyes on in the year ahead is the potential evolution of LLMs with something called Large Agentic Models (LAMs). LAMs are advanced systems that can perform tasks and make decisions by interfacing with other human users or other automated tools. Unlike traditional AI systems that respond to user prompts, LAMs are designed to understand their environment and take actions to achieve their assigned goals without direct human intervention, according to TechTarget. But perhaps the most important technology innovation with LLMs for legal professionals is that data security and privacy safeguards are being placed front and center with the newest tools in development. Secure cloud services are more readily available, data sanitation and anonymization are standard in training models, encryption is more reliable than ever, access controls are vastly improved, and there are sound data governance protocols around the retention of prompt inputs and response outputs. At LexisNexis, we have followed a product development plan that embraced Gen AI technology in a deliberate manner so we can capture the upside of these tools developed specifically for the legal domain, while mitigating the potential risks associated with the first generation of the open Web Gen AI tools, such as ChatGPT. Lexis+ AI is our breakthrough Gen AI platform that is transforming legal work by providing a suite of legal research, drafting, and summarization tools that delivers on the potential of Gen AI technology. Its answers are grounded in the world’s largest repository of accurate and exclusive legal content from LexisNexis with industry-leading data security and attention to privacy. By saving time with Lexis+ AI enabled tasks, legal professionals have more time to do the work only they can do. In fact, our customers have reported time savings of up to 11 hours per week using Lexis+ AI. To learn more or to request a free trial of Lexis+ AI, please go to www.lexisnexis.com/ai.
