Med-PaLM

Med-PaLM is a large language model from Google Research that has been adapted for medical purposes.

Med-PaLM is a large language model (LLM) designed to provide high quality answers to medical questions.

Med-PaLM harnesses the power of Google’s large language models, which we have aligned to the medical domain and evaluated using medical exams, medical research, and consumer queries. Our first version of Med-PaLM, preprinted in late 2022 and published in Nature in July 2023, was the first AI system to surpass the pass mark on US Medical License Exam (USMLE) style questions. Med-PaLM also generates accurate, helpful long-form answers to consumer health questions, as judged by panels of physicians and users.

We introduced our latest model, Med-PaLM 2, at Google Health’s annual health event The Check Up, in March, 2023. Med-PaLM 2 achieves an accuracy of 86.5% on USMLE-style questions, a 19% leap over our own state of the art results from Med-PaLM. According to physicians, the model's long-form answers to consumer medical questions improved substantially. In the coming months, Med-PaLM 2 will also be made available to a select group of Google Cloud customers for limited testing, to explore use cases and share feedback, as we investigate safe, responsible, and meaningful ways to use this technology.
