Notius Labs founder argues domain expertise matters more than AI models in building effective AI products

AI-summarised brief · reviewed before publication

Chris Lovejoy, founder of Notius Labs, argues that domain expertise is more crucial than AI models in building effective AI products. He presented a framework with three distinct roles for domain experts: Oracle, Evaluator, and Architect. Each role serves a different function as products grow, and the choice depends on the specific use case and scale. Companies often hire domain experts too late or fail to integrate them into the product development process.
