Arjun K. Manrai, PhD, from Harvard Medical School, joins the discussion on the capabilities of open-source large language models (LLMs) versus proprietary ones for complex medical diagnoses. They delve into a recent study revealing that models like Meta's LLaMA 3.1 can match GPT-4's diagnostic abilities, challenging the notion of proprietary superiority. The conversation also highlights the benefits of privacy and accessibility in healthcare, and the vital role of AI chatbots in supporting physicians while underscoring the need for human oversight.
