About Kai-fu Lee
Kai-fu Lee, CEO of Sinovation Ventures and chairman of 01.AI, appeared on the podcast "Machine Learning, How Did We Get Here?" hosted by Tom Mitchell on December 1, 2025. Lee discussed his early work as a PhD student in the 1980s applying machine learning, specifically hidden Markov models, to speech recognition. He described achieving 96% accuracy in his system, which he called a "big breakthrough" at the time. Lee noted that speech recognition is "technologically solved," with remaining issues being "just engineering."
During the interview, Lee offered advice to academics, stating that the path forward in generative AI built on transformers requires "giant computer infrastructure" that academic institutions lack. He suggested that researchers either work with companies that have resources and data, or "go invent the next thing." Lee expressed surprise that the transformer architecture and scaling law "could carry us as far as it did."
