Bio

Lin Junyang is a Chinese computer scientist, born in 1993. He is the former tech lead of the Qwen team at Alibaba, the position he held from April 2023 until his resignation on 3 March 2026. He held the Alibaba P10 senior-leadership tier and was the youngest P10 executive at Alibaba at age 32. His next role has not been publicly announced as of May 2026.

Education

Lin completed a master's degree in linguistics at Peking University, where he studied both computer science and linguistics. Earlier degrees are not publicly disclosed in English-language sources.

Career

Lin joined Alibaba's DAMO Academy in July 2019 directly from Peking University and remained at the company for his entire pre-Qwen career. The early DAMO period covered the M6 and OFA model lines, two of Alibaba's early multimodal foundation models, alongside contributions to other research projects in the academy.

He took on tech-lead responsibility for the Qwen team in April 2023, around the time Alibaba began publishing the open-weights Qwen line under permissive licensing. Under his leadership the Qwen series scaled from a side project within DAMO into one of the largest open-weights model portfolios in the industry, with over six hundred million model downloads globally across Hugging Face and ModelScope by the time of his departure. The releases under Lin's tech-lead tenure spanned the Qwen 1, 1.5, 2, 2.5, and 3 series, including the Qwen 3.5 small open-weight models released the day before his resignation announcement.

Lin's public-engagement style during the Qwen period was distinct from peer Chinese frontier-lab tech leaders. He maintained an active English-language presence on X (formerly Twitter) and engaged regularly with the Western open-weights community on Hugging Face, GitHub, and conference channels. He was also the principal author of public-facing communications on Qwen's competitive positioning, including statements characterizing the gap between Chinese and US frontier capability that Bloomberg and others cited at the time of his resignation.

He resigned from Alibaba on 3 March 2026. Bloomberg and TechCrunch reported the departure as approved by Alibaba leadership, with Jingren Zhou, the Alibaba Cloud Intelligence CTO, taking on temporary oversight of the Qwen team and Alibaba subsequently recruiting Zhou Hao from Google DeepMind as Lin's longer-term replacement. Lin's next role has not been publicly announced as of May 2026.

Notable contributions

Lin's contributions through Alibaba spanned multimodal foundation modeling and the open-weights Qwen line.

• M6 multimodal model. Co-author of the M6 multimodal pre-trained model from the early DAMO period.
• OFA (One For All) model. Co-author of the OFA unified multimodal pre-trained model.
• Qwen line tech leadership (April 2023 to March 2026). Steered the Qwen open-weights model series from a side project within DAMO Academy to over six hundred million downloads globally.
• Open-weights advocacy. Public engagement with the global open-weights community on Hugging Face, GitHub, and X across the Qwen tech-lead period.

Affiliations

• Peking University: Master's student in linguistics, with study in computer science and linguistics.
• Alibaba DAMO Academy: Researcher and Tech Lead, July 2019 to March 2026.
• Alibaba Qwen team: Tech Lead, April 2023 to 3 March 2026.

Position in the field

As of May 2026, Lin is the principal architect of one of the largest open-weights model portfolios in the industry. The Qwen series under his tech leadership crossed a download threshold that has been cited as evidence of the open-weights distribution model's reach in the post-Llama, post-DeepSeek period. Industry coverage of his departure characterized the move as a significant inflection point for the Qwen team and for Alibaba's broader AI strategy.

The framing of Lin in Western coverage during the Qwen period combined two roles: a senior research engineer at one of China's largest internet companies and a public communicator who engaged the Western open-weights community in English at a frequency uncommon among Chinese frontier-lab tech leaders. Bloomberg's coverage of his resignation cited a public statement he had made at the time of Qwen 3 about the capability gap between Chinese and US frontier models, framed in industry coverage as a candid acknowledgment uncommon in Chinese-lab public communications.

His next role has not been publicly announced as of May 2026.
