Qwen 3.5 Launch Overshadowed by High-Profile Departure
-

Alibaba’s Qwen team introduced its Qwen 3.5 Small Model series with four parameter sizes — 0.8B, 2B, 4B, and 9B — positioning them as native multimodal systems optimized for on-device AI and lightweight agent use cases. The launch drew global attention, including praise from Elon Musk, who described the models as demonstrating “impressive intelligence density.”
However, the excitement was quickly tempered by Junyang Lin’s unexpected departure. Colleagues and ecosystem partners publicly expressed shock, describing his influence on Qwen’s engineering direction and global developer outreach as foundational. With Alibaba remaining silent on the circumstances and leadership transition, the move introduces uncertainty at a time when China’s AI ambitions are accelerating on the global stage.
