AstraZeneca's Research Assistant: An LLM-Based System for R&D

ai-technology · 2026-08-15

AstraZeneca has rolled out a new tool called Research Assistant, which uses LLM technology to support scientists and clinicians with biomedical research. This system has a chat-like interface and pulls together information from various sources like scientific articles, knowledge graphs, chemistry databases, clinical trials, and more. It offers a quick response feature for simple questions and a detailed mode for complex inquiries. Users can verify the information since answers are backed by sourced evidence. Additionally, a technical note outlines the system's design and findings from its extensive use to improve R&D processes at AstraZeneca. This development is detailed in a paper on arXiv in the Computer Science > Artificial Intelligence section.
