[After Seed and Flow, ByteDance Establishes Another AI First-Level Department to Oversee Model Data] According to monitoring by Beating, ByteDance has established another AI first-level department called 'AI Data and Security,' which operates parallel to departments like Seed and Flow and is led by Wang Yinglei. Following Seed's focus on models and Flow's focus on products, ByteDance has once again elevated a core AI capability to an independent level. The new department integrates several data teams, including the former Global Data team, the Group Data Middle Platform (DMC), and AIDP under Flow. ByteDance's official job postings now feature the 'AI Data and Security' team, which is responsible for providing cross-modal data for Seed's foundational models and AI products, covering data procurement, production, cleaning, evaluation, and other processes. Wang Yinglei previously oversaw TikTok LIVE for an extended period and transitioned last year to lead TikTok's Platform Responsibility team. At the time, TikTok stated that he had been responsible for the global launch and expansion of TikTok LIVE. Recently, ByteDance has also explicitly required Seed to focus on independent research and development, avoiding reliance on distilling competitors' models. Meanwhile, the company is training a new model with a scale that could reach up to 10 trillion parameters. The larger the model and the greater the emphasis on independent training, the higher the demand for high-quality training and evaluation data. [Original Link]
