# ByteDance reorganizes Seed foundation-model team amid reported 5 trillion-parameter model plans > Source: > Published: 2026-08-20 06:15:26+00:00 ByteDance’s Seed foundation-model division has reportedly completed a new round of internal restructuring. Its foundation-model team has created four new first-level departments: Pretrain Data, Horizon RL, Product Posttrain-Work and Product Posttrain-Chat. The Work team will focus on business applications and agentic capabilities for products including Doubao and Dola, while the Chat team will handle consumer-facing dialogue models. The restructuring follows separate reports that ByteDance is discussing a model with more than 5 trillion parameters, but that plan remains at an early stage and has not been officially announced as a product.
