Alibaba Group experienced a notable share decline in Hong Kong trading on Wednesday after the unexpected announcement that Junyang Lin, the technology lead overseeing the company’s Qwen AI model efforts, would leave his role.
Shares in Alibaba (HK:9988) dropped 5.1% to HK$127.90, making the stock one of the heavier negative contributors to the Hang Seng index, which fell by nearly 3% during the session.
Lin disclosed his departure in a short message on X, writing: "me stepping down. bye my beloved qwen," and provided no further details about his decision. The announcement came a day after the company released a new line of smaller Qwen AI models. The reason for Lin’s exit was not immediately clear.
Observers noted that Lin had engaged publicly only shortly before his announcement; a day prior he responded to a post from Elon Musk, the CEO of Tesla and xAI, that commended Qwen’s "intelligence density." No additional explanation accompanied Lin’s later post.
The timing of the resignation - immediately following a product release - has heightened attention on Alibaba’s AI programme. The company had been actively promoting its AI offerings during recent Lunar New Year holiday activity. Lin’s departure prompted commentary about the potential effect on Alibaba’s broader artificial intelligence initiatives as it competes with rivals mentioned in public reporting.
