DeepSeek Restructures Teams to Form Unified Product Department
DeepSeek has consolidated its Harness, Web, App, and Platform teams into a newly formed 'Product Department' led by Cui Tianyi. Cui confirmed that this new division will oversee all product, design, and research and development operations for the company. This organizational restructuring streamlines DeepSeek's workflow by bringing its agent runtime framework, web interfaces, mobile apps, and core platforms under a single leadership structure. It indicates a strategic shift toward more cohesive and accelerated product development as the company scales its AI agent ecosystem. The newly appointed head of the Product Department, Cui Tianyi, joined DeepSeek in March after building a background that includes competing with six ACM Asia Regional gold medals and working at Jane Street for nine years. The restructuring closely follows the recent release of the DeepSeek Harness desktop preview v0.2, an open-source agent runtime framework built on an 'everything-is-a-plugin' philosophy.
## BACKGROUND
DeepSeek Harness is an open-source agent runtime framework created by DeepSeek AI that allows language models to execute tasks, manage sessions, and use tools through an architecture where everything functions as a plugin. An agent runtime or harness acts as the crucial scaffolding that transforms a standalone large language model into an active, autonomous agent capable of executing multi-step workflows.
