Med-PaLM is an artificial intelligence-powered chatbot tool developed by Google and DeepMind. It is specifically designed to generate “safe and helpful answers” to questions posed by healthcare professionals and patients. This large language model is aligned to the medical domain and is based on the 540-billion parameter PaLM model.
Features of Med-PaLM
- Specialized Healthcare Focus: Med-PaLM is designed to answer healthcare-related questions, operating within narrower parameters. It has been trained on seven question-answering datasets spanning professional medical exams, research, and consumer queries about medical matters.
- Diverse Training Datasets: The model was trained on six existing medical Q&A datasets (NedQA, MedMCQA, PubMedQA, LiveQA, MedicationQA, and MMLU), and the developer teams also created their own HealthSearchQA, using questions about medical conditions and associated symptoms.
- Limited Public Access: Currently, Med-PaLM cannot be tested by the general public, but the research behind it is available for reading. It represents a significant step in the application of AI in the medical field, providing specialized responses to medical inquiries.
