Alibaba Qwen tech lead steps down right after major model launch
Alibaba Qwen's central technical leader Junyang Lin just announced he is stepping down from the open-weight project, only a day after releasing the Qwen 3.5 small models. Colleagues called the abrupt exit an immense loss, with one teammate hinting the departure wasn't Lin's choice. The shakeup comes right as China's top open-source model family gains global momentum.
