 Christopher Olah (born 1991 or 1992 ) [ 1 ] is a Canadian machine learning researcher and a co-founder of Anthropic . [ 1 ] [ 3 ] He is known for his work on neural network interpretability, particularly mechanistic interpretability , and for research and tools that visualise internal representations in neural networks. [ 4 ] [ 5 ] In 2025, Forbes reported he had become a billionaire due to his ownership in Anthropic. [ 1 ] 

 Early life

 [ edit ] 
 Olah was born in Canada. [ 2 ] He studied mathematics at the University of Toronto for one year before dropping out. [ 6 ] According to an interview with Wired magazine, he left university at age 18 without earning a degree to "support a friend accused of terrorism". In 2012, he received a Thiel Fellowship , which supported him in pursuing independent work. [ 2 ] [ 3 ] 

 Career

 [ edit ] 
 Olah has worked on interpretability research at Google Brain , OpenAI , and Anthropic. [ 7 ] [ 8 ] He started as an intern at Google Brain in 2015, working his way up to a research scientist. [ 6 ] In 2017, Olah co-founded an interactive machine learning publication, Distill, with the goal of creating more transparency surrounding machine learning. [ 9 ] [ 10 ] A paper published in Distill led Olah to a job at OpenAI. [ 9 ] 

 

 In 2018, he left Google Brain to lead OpenAI's interpretability team. [ 6 ] In 2020, he left OpenAI and co-founded Anthropic a year later. [ 6 ]
