Singhal: Evaluators can barely distinguish Med-PaLM 2 answers from human physicians
“One thing we're seeing with MedPOM-II as we get closer to physician-level performance on medical question answering is that it's hard to tell the difference anymore. It's hard to tell the difference between different models. It's hard to tell the difference be…”

Singhal: Flan-PaLM was the first AI model to pass the USMLE
“When we took a variation of POM, the FlanPOM model, which was, again, work from Jason Wei and team you know, this is an instruction to a model that's been trained to follow instructions better. You know, again, it was able to perform quite well out of the box,…”

Singhal: Specialized AI models will assist radiologists in the near term
“I think where there might be more of a need for specialized models Is when it comes down to kind of higher stakes workflows, and I think that might look in the short term more like a physician's assistant. And so imagine, for example, an agent that can work wi…”

Singhal: Med-PaLM and Med-PaLM 2 were trained without patient health information
“Like for example, MedPOM and MedPOM-II are trained without any patient health information. They, they're just kind of taking all the knowledge of POM and POM-II and then just kind of Aligning them and making them behave in a certain way.”
