About Sam McCandlish


S am McCandlish is a distinguished researcher in artificial intelligence and a key figure in the AI safety movement, best known as a co-founder of the research company Anthropic. With a background in theoretical physics, having earned his Ph.D. from the University of California, Berkeley, McCandlish brought a rigorous scientific approach to the burgeoning field of AI. He began his technology career at OpenAI, where he rose to become a research team lead and played an instrumental role in the development of groundbreaking models, including the influential GPT-3.

In 2021, McCandlish joined a significant exodus of senior researchers, led by Dario Amodei, from OpenAI. This group left due to fundamental disagreements over the direction of AI development, particularly concerning safety protocols and commercialization pressures. They co-founded Anthropic as a public benefit corporation with a core mission to build reliable, interpretable, and steerable AI systems. At Anthropic, McCandlish continues his research-focused work, contributing to the creation of the Claude family of AI models, which are designed with a constitutional AI framework to ensure they remain helpful, harmless, and honest, positioning the company as a major and safety-conscious competitor in the AI landscape.
