This newsletter focuses on the practical applications of generative AI (GenAI) in the enterprise, specifically within the healthcare and life sciences industries. It offers insights on how to implement GenAI effectively, including evaluating the performance of Large Language Models (LLMs) used as judges in Retrieval Augmented Generation (RAG) systems, and the importance of implementing "guardrails" to ensure safety and compliance in AI operations. The newsletter emphasizes the need for clear evaluation criteria for LLMs and highlights key considerations for building secure and reliable GenAI systems. It also provides practical advice on building an Enterprise AI Council and using the 70-20-10 rule to prioritize GenAI initiatives.
