Wang Huaian is the founder of Babytree. He believes that the emergence of ChatGPT marks the end of the battle for large models, and China should seize the opportunity to develop vertical domain Copilots. He is currently developing an oral history product called "Riverside," aiming to have a Sima Qian by the side of every individual, enabling ordinary people to easily record their own life stories. Wang Haoan will collaborate with his friend Lu Qi on this project, both believing that it concerns all of humanity and carries an idealistic color. Wang Huaian admires Sam Altman's entrepreneurial qualities, which have brought OpenAI to where it is today. He states that this is the first time in history that everyone can leave a mark, and this project may rewrite history.
