EPISODE SUMMARY

In this episode of No Priors, featuring Sarah Guo and Karan Singhal, No Priors Ep. 17 | With Karan Singhal explores google’s Med-PaLM 2 Aims to Safely Transform Healthcare With AI Karan Singhal, a lead researcher on Google’s Med-PaLM 2, explains how large language models are being adapted for high‑stakes medical use, with a focus on safety, accuracy, and responsible deployment. He traces the evolution from PaLM to PaLM 2 and Med-PaLM, detailing methods like instruction prompt tuning and improved pretraining objectives. The discussion digs into evaluation challenges, regulatory and privacy barriers, and why medical workflows can be a powerful testbed for AI alignment and safety research. Looking ahead, Singhal expects LLMs to raise the global standard of care, augment clinicians and scientists, and help solve key scientific and medical problems—if society can set realistic, benefit-aware safety bars.
