On June 20, a source told reporters that ByteDance founder Zhang Yiming often travels between Beijing and Singapore, and is particularly concerned about AI business. Since the second half of last year, he has participated in a review and discussion meeting of the seed core technology team every month. The above-mentioned person also said: "There is no such thing as 'returning to the front line'. At present, Zhang Yiming is still based in Singapore and pays great attention to technology. In Singapore, he mainly communicates with researchers and regularly returns to China to communicate with technical backbones. Zhang Yiming focuses on cutting-edge technologies for the future. His role is more like that of Google co-founder Sergey Brin after his return: focusing on the core AI research team and spending a lot of time dealing with researchers."
