Alibaba’s Qwen Faces Turmoil as Three Core Technical Leaders Depart Abruptly
Three core technical leaders of Alibaba's artificial intelligence team, Qwen, have simultaneously left the company, sparking significant concern across the global open-source AI community regarding the future continuity of one of China’s flagship large language model projects.
Junyang Lin (林俊旸), the technical lead widely regarded as the key architect of the Qwen series, announced he was stepping down on social media platform X late on March 3, 2026. His abrupt departure was immediately followed by the exits of at least two other central figures, core researchers Binyuan Hui (惠斌元) and Kaixin Li (李凯鑫).
The collective exodus occurred less than 24 hours after the team completed the intensive launch of the new Qwen3.5 series of small models. While Alibaba has not issued an official statement regarding the personnel changes, social media comments from colleagues suggest the departures may have been involuntary, raising questions about potential strategic shifts or internal conflicts within Alibaba Cloud’s AI division.
The Core Team Exodus and Critical Timing
Junyang Lin, who joined Alibaba’s DAMO Academy in 2019 and became one of the company's youngest high-level technicians, has been the public face of Qwen, managing model releases, benchmarks, and developer relations. His exit was closely coupled with Binyuan Hui, a researcher focused on coding agents and a co-author of the Qwen technical report, and Kaixin Li, a core contributor to the Qwen3.5 and VL models.
The timing of the departures is notably acute. According to team members, staff were working until dawn on March 3 to finalize the release of the latest small models. The leadership changes were executed the following day, suggesting a predetermined decision delayed until the product launch cycle was complete. A post from colleague Chen Cheng to Lin stating, "I know leaving wasn't your choice," indicates the move was likely not a voluntary resignation.
Speculation Over Strategic Clashes and Management Shifts
While there is no official explanation, unconfirmed speculation within the developer community points to internal restructuring at Alibaba Cloud. One prevalent theory suggests executives appointed a new technical leader, rumored to be Hao Zhou formerly of Google DeepMind, leading to friction over technical direction and control.
Another possibility widely discussed involves pressure on the foundational model team to meet consumer-facing KPIs, such as daily active users (DAU). This would represent a potential conflict with the team's established open-source priority route. Alibaba launched a consumer-facing Qwen App in November 2025 and reportedly trails domestic competitors like ByteDance in user scale.
Risks to Open-Source Roadmap and Execution
The immediate impact on Qwen’s operations appears muted, with GitHub repository updates and model releases proceeding as scheduled on March 3. However, the loss of the team lead and key contributors creates substantial medium-term uncertainty regarding execution continuity.
Qwen's technical roadmap emphasizes long-term investments in areas such as large-scale reinforcement learning and global language coverage. The departures have shaken confidence among downstream developers and enterprise users who rely on the stability of the Qwen ecosystem. Additionally, Kaixin Li noted that plans for a potential international Qwen base in Singapore are likely shelved following Lin’s departure.
