What Google Medical AI Chatbot “Med-PaLM 2” is about?

Google has an AI tool designed specifically for medical and health related purposes called “Med-PaLM 2” which now the firm starts testing it in hospitals.

The tech-giant Google has been committed itself to revolutionize completely into the AI field, rolling out tools or features and platforms for every realm possible. Primely focused on search-engine, the company also brings AI to all its products and services, including Gmail, Maps, Android and now in medical sector.

Called as “Med-PaLM 2”, the AI tool is built upon Google’s steadfast “PaLM 2”, an artificial general intelligence (AGI) model of Google. PaLM-2 supposes to be the backbone of the firm’s AI arm, underpinning almost all AI tools of Google, including Bard.

In the race of AI, Google enters medical industry with this Med-PaLM 2, which it believes that Med-PaLM 2 would provide better accurate answers for healthcare conversations than generalized chatbots like Bard, Bing and ChatGPT.

Google strives to bring you the AI-doctor, which might substitute as an health official for addressing basic medical-related queries.

Med-PaLM 2 was trained on a curated set of medical expert demonstrations and it will be particularly helpful in countries with more limited access to doctors. While other AI platforms such as PubMed GPT, Dragon failed to cross the approximate medical pass mark of US Medical licensing exam, i.e., 60%, Med-PaLM 2 scored 85.4% in the exam, Google claims.

Google has started testing Med-PaLM 2 at the Mayo Clinic research hospital from April, where it answers to questions about and related to medical information, WSJ reports.


As any medical prescription or support deals directly with the lives of people, the AI needs to be rigorously factual and reliable, which quite probably none of the AI models had reached till now. Though Med-PaLM 2 scores way more than other models, it still has a long way to go.

In a study, physicians found more inaccuracies and irrelevant information in answers provided by Google’s Med-PaLM and Med-PaLM 2 than those of other doctors.

As per the firm’s senior research director Greg Corrado, Med-PaLM 2 is still in early stages and the firm believes that its AI can be highly beneficial in healthcare in future.
