The competition in China's AI field is essentially a competition of people; those who excel will continue to excel in their next project. 1. The two core AI teams at ByteDance, Doubao and Jimeng, are led by founders of companies acquired by ByteDance and are pioneers in building Douyin (TikTok), making them business geniuses. - Zhu Jun, head of Doubao, is the founder of Musically, the predecessor to Douyin's overseas version, which was later acquired by ByteDance.

One success can be a coincidence, but two successes demonstrate strength. - Zhang Nan, head of Jimeng, was the first person to build Douyin, experiencing its development from scratch.

Her personal experience includes creating a photo-sharing community, and after being acquired by ByteDance in 2013, she was responsible for the UGC business. 2.

He has twice brought Alibaba's products to over 100 million MAU. - Lin Junyang, head of the Tongyi Qianwen large-scale model technology, holds a bachelor's degree in Computer Science from Peking University and a master's degree in Linguistics and Applied Linguistics. He is Alibaba's youngest P10-level technical expert. He joined Alibaba DAMO Academy in 2019 and participated in ultra-large-scale pre-trained models in 2020.
