Merged summary
TL;DR - ByteDance reorganized its Seed foundation-model team around centralized pretraining data, reinforcement learning, and separate post-training groups for workplace agents and consumer chat. The shift reflects growing competition around unified multimodal models, reasoning, and agents that execute real tasks.
- Pretrain Data consolidates text, code, vision, and speech data pipelines to support Omni multimodal and large-scale models.
- Horizon RL centralizes reinforcement learning for scaling, reasoning, and vision, building on Seed’s DAPO and VAPO work.
- Product Posttrain-Work targets GUI and office agents, including tool use, computer interaction, and complex task execution for Doubao and Dola.
- Product Posttrain-Chat focuses on search, dialogue, personalization, safety, and inference costs for consumer-facing products.
