LexisNexis Amplifies Its AI Capabilities with Lexis+ AI’s Public Release

Overview of Lexis+ AI

In an ambitious move, LexisNexis has officially unveiled its generative artificial intelligence system, Lexis+ AI, for its clientele in the United States. This release on 25 October 2023, following its initial revelation in May, showcases enhanced features, a revamped user interface, and a plethora of instructional resources.

Jeffrey Pfeifer, the chief product officer for LexisNexis’s operations in North America, Ireland, and the U.K., elucidated during a recent press briefing, “In designing Lexis+ AI, we’ve worked to enable multi-turn conversations, deliver a high level of secure interaction [and] ground our answers in trusted content, all with an emphasis on hallucination-free linked citations presented in line with our answers.”

Enhanced Functionalities of Lexis+ AI

The platform revolves around four main functionalities: search, summarize, draft, and the freshly introduced multiple-document upload. This new addition facilitates the simultaneous upload of up to ten documents, granting users the flexibility to summarize individual or multiple documents, alongside the convenience to inquire about the uploaded content. Pfeifer underscored the user’s control over their data, stating that files can be instantaneously removed by the user or would be automatically purged post a session or after a ten-minute inactivity duration.

Building on its repertoire, Lexis+ AI is fortified with a diverse range of materials spanning primary law, secondary references, guidelines, constitutions, court regulations, and selected federal agency verdicts. Pfeifer hinted at the integration of more content in subsequent phases.

Shepard’s Citations Service now bolsters the platform’s citation references, empowering users with direct links to primary documents. Paying heed to user feedback, LexisNexis has also refreshed Lexis+ AI’s landing page to guide users in specific tasks seamlessly.

One noteworthy enhancement is the jurisdiction filter, curated to refine results swiftly. The platform also introduces sample cues and insights on responses from the AI assistant, refining the user’s interaction. Pfeifer elaborated on this, emphasizing the model’s capability to recall prior questions, thereby providing contextualized responses.

Recognizing the users’ demand for a more navigable interface, LexisNexis embedded an array of educational tools like hints, training modules, and walkthroughs within Lexis+ AI.

Underlying Technology and Pricing Structure

Adopting a multi-model strategy, LexisNexis harnesses the prowess of both Anthropic’s Claude 2 and OpenAI’s GPT-4 language models, optimizing their capabilities. Pfeifer acclaimed this strategy, particularly praising Anthropic’s edge in summarization tasks due to its “significantly higher token volume than other models.”

The cost of Lexis+ AI will oscillate based on the chosen package, complementing the existing suite of tools in Lexis+. Pfeifer hinted at competitive pricing for smaller firms, offering tailored modules at varied rates.

As LexisNexis forges ahead, Pfeifer teased forthcoming updates to Lexis+ AI, encompassing potential collaborations with staples like Microsoft Word and Outlook. The horizon looks promising as LexisNexis endeavors to redefine the boundaries of AI-powered research and analytics.
