Alibaba Qwen AI faces major disruption after one key leader steps down
Alibaba’s Qwen AI project faces uncertainty after the departure of a central technical leader, just as the company accelerates competition with new multimodal model releases.
Junyang Lin, a central technical leader of Alibaba’s Qwen AI project, has stepped down just one day after the company unveiled its Qwen 3.5 small models. Lin, who joined Alibaba in 2019 and joined the Qwen team in 2023, did not provide details about his decision.
His departure comes at a sensitive moment, as Qwen has emerged as one of China’s most prominent open-weight AI initiatives. The project is a core element of Alibaba’s strategy to compete with leading US developers such as OpenAI, Google, and Anthropic amid intensifying global AI competition.
Alibaba’s newly launched Qwen 3.5 Small Model series comprises four multimodal models with 0.8B to 9B parameters. The systems are designed for on-device deployment and lightweight AI agents, reflecting a focus on efficient and adaptable AI applications.
The release attracted attention from figures including Elon Musk, who commented on the models’ performance. Internally and across the AI ecosystem, including partners linked to Hugging Face, Lin’s exit was described as a significant loss, particularly given his role in advancing open-source development and strengthening global developer engagement.
