April 14, 2023 - This week, Google provided progress updates on multiple of the company’s healthcare artificial intelligence (AI) initiatives, including an announcement that its medical large language model (LLM), Med-PaLM 2, would become available to select customers for limited testing. 

Med-PaLM 2 is a version of Google’s original LLM, known as the Pathways Language Model (PaLM). PaLM was introduced last year, and Med-PaLM, a version tuned for the medical domain, was developed shortly after.  

Med-PaLM achieved a passing score on USMLE-style multiple choice and open-ended questions, and Med-PaLM 2 recently scored 85 percent on similar questions. However, these tests highlighted gaps in the model’s ability to effectively answer medical questions, which Google indicated it would address through additional research and testing.
