Legal AI: LexisNexis Expects Us!

The advent of OpenAI's ChatGPT sparked a revelatory moment in the industry, heralding a new era where AI's potential to enhance legal research became unmistakably clear. However, thanks to an idiot in New York who didn’t double check a Chat GPT generated brief, all anyone talked about was the hallucinated cases. As a result, the old-timers and in-the-box thinkers all dismissed Ai as being universally inaccurate and unreliable.

Enter LexisNexis. They have unveiled their latest marvel, Lexis+ AI, a generative AI tool that promises to revolutionize the way legal research is conducted

LexisNexis, a veteran in embracing machine learning and artificial intelligence, has been at the forefront of such technological advances, having introduced natural language processing for legal searches as early as the 1990s and incorporating large language models since 2018​

Lexis+ AI distinguishes itself with a conversational interface, allowing users to engage with the AI more naturally, akin to dialoguing with a knowledgeable colleague. This user-centric approach marks a significant shift from traditional research methods, characterized by broad searches followed by a meticulous process of narrowing down results. Lexis+ AI's conversational model enables a more dynamic and efficient research process, adeptly handling queries that include situational context and generating outputs tailored to the attorney's perspective, the objectives of their research, and the ideal format for responses​

​At its core, Lexis+ AI is designed to aid the day-to-day practice of law, offering functionalities such as drafting documents, conversational search, document summarization, and analysis of user-uploaded documents. Drawing upon LexisNexis' extensive libraries, the tool continually evolves, integrating new content and data to enhance its capabilities​

One of the most intriguing aspects of Lexis+ AI is its integration of multiple large language models (LLMs), such as GPT-4 and Anthropic’s Claude 2. This multi-model approach enables the tool to select the most effective model based on the specific prompt, ensuring the delivery of the best possible results. Each model has been fine-tuned for legal research, ensuring that Lexis+ AI remains a potent research assistant, complementing the traditional, yet still potent, resources offered by LexisNexis​

In essence, Lexis+ AI is not just a tool but a testament to the ongoing transformation of legal research, where efficiency, accuracy, and user-centricity converge to create a futuristic yet accessible legal research experience.
