ByteDance Establishes Top-Level AI Data and Security Department

New unit led by Wang Yinglei consolidates data teams to support Seed models, emphasizing autonomous training with up to 10 trillion parameters.

Woofun AI reports that ByteDance has established a first-level 'AI Data and Security' department, operating parallel to Seed and Flow. Headed by Wang Yinglei, the unit integrates data teams from Global Data, DMC, and AIDP to provide cross-modal data for Seed's foundational models. The department handles data procurement, generation, cleaning, and evaluation. This restructuring supports ByteDance's focus on independent model development rather than distillation, with new models reaching up to 10 trillion parameters requiring high-quality training data.
