A large language model from Google Research, designed for the medical domain.
Med-PaLM is a large language model (LLM) designed to provide high quality answers to medical questions. Our second version, Med-PaLM 2, is one of the research models that powers MedLM– a family of foundation models fine-tuned for the healthcare industry. MedLM is now available to Google Cloud customers who have been exploring a range of applications, from basic tasks to complex workflows.
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 (>60%) in the U.S. Medical Licensing Examination (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 Med-PaLM 2 at Google Health’s annual event, The Check Up, in March 2023. Med-PaLM 2 was the first to reach human expert level on answering USMLE-style questions. According to physicians, the model's long-form answers to consumer medical questions improved substantially.
