Today’s guest is Arun Subramaniyan, Founder and CEO of Articul8. After earning his PhD simulating jet engines and leading GE's digital twin revolution, he's helping Articul8 build domain-specific AI solutions for the world's most complex industries - from Wall Street to electrical grids and aerospace design. Arun joins us on today’s show to share why simply plugging in large language models isn’t enough for industries with complex, high-stakes processes. Arun explains how enterprises can move beyond general-purpose AI by creating domain-specific models that understand specialized terminology and data, and how orchestration frameworks—what he calls the “Model Mesh”—enable these models to work together dynamically to answer nuanced business questions.
