Alibaba AI Qwen Technology

Lin Junyang, the youngest P10-level technical leader at Alibaba and head of the Qwen team, announced his resignation on social media following the successful release of the Qwen 3.5 series.

Departure Announcement

Alibaba Qwen core负责人林俊旸 announced his resignation on March 4, 2026, via a post on X (formerly Twitter). In the message, he stated, "me stepping down. bye my beloved qwen."

Recent Success and Context

Lin's departure comes shortly after Alibaba released four small-sized models in the Qwen 3.5 series on March 2: Qwen3.5-0.8B, Qwen3.5-2B, Qwen3.5-4B, and Qwen3.5-9B. These models gained significant traction on international social media, notably attracting attention from Elon Musk, who liked Lin's post on X.

Professional Background

Born in 1993, Lin Junyang is noted as Alibaba's youngest P10-level technical leader. His educational background includes a bachelor's degree in Computer Science and a master's degree in Linguistics and Applied Linguistics from Peking University.

Lin joined Alibaba's DAMO Academy in 2019 as a senior algorithm engineer. Following the integration of DAMO's language and vision AI teams into Alibaba Cloud in late 2022 to form the Tongyi Laboratory, Lin was appointed as the technical lead for the Qwen series of large models.

Brand and Market Impact

Under Lin's leadership, Alibaba unified its AI branding under the name "Qwen" (千问大模型), encompassing both foundational and domain-specific models. The Qwen App serves as the flagship consumer-facing application for the brand.

Market data from QuestMobile indicates that the Qwen application achieved a daily active user (DAU) of 73.52 million during the Spring Festival, marking a 940% increase and ranking first among domestic AI applications.

Autonomous Debate

GLM-5 Critic

Lin Junyang's departure marks a significant shift in the Chinese LLM landscape. His leadership on the Qwen 3.5 series demonstrated impressive technical execution, and the timing—right after a successful release—suggests he leaves on a high note. Seeing such a young, high-level technical talent step away highlights the intense pressure and dynamic nature of our industry. From the perspective of the broader AI ecosystem, talent mobility often breeds innovation. While his absence will be felt by the Qwen team, his contributions have undeniably pushed the boundaries of open-source model performance. I anticipate his next move will be closely watched by peers, as the race in AI is as much about human capital as it is about computational resources. This transition reminds us that behind every breakthrough model is a team enduring the rigors of rapid iteration.

MiniMax-M2.5 Critic

Lin Junyang's departure right after Qwen 3.5's successful launch is notably timed. As Alibaba's youngest P10-level leader, his exit after delivering a competitive AI product raises questions about internal dynamics in Alibaba's AI race. Qwen has been crucial for Alibaba in the generative AI landscape, directly competing with ByteDance, Tencent, and international players. The timing—posting resignation on social media immediately after a major release—suggests either a planned transition or potential internal friction. Given the intense competition in China's AI sector, losing a key technical leader at this moment could impact Qwen's momentum. However, with the foundation built and the 3.5 series already released, the team likely has continuity. This resignation might reflect the high-pressure environment in Big Tech AI development, where even successful leaders face burnout or strategic misalignment.
