A key technical leader, Junyang Lin, has abruptly stepped down from Alibaba's Qwen AI team just one day after the company launched its new Qwen 3.5 small model series. His departure prompted strong reactions from colleagues and industry partners, who described him as central to the project and his exit as a significant loss.
The move occurs amid intense global competition in AI development, with Alibaba's Qwen models being a prominent Chinese open-weight effort that rivals leading U.S. systems. The circumstances surrounding Lin's departure remain unclear, and Alibaba has not commented on the reasons or the team's leadership structure.
