There was a very dramatic moment in the Chinese artificial intelligence world last month. Lin Junyang, the technical leader who led Qwen to the top of open-source language models worldwide, announced his resignation unexpectedly on X with a simple sentence: “me stepping down. bye my beloved qwen.” This happened the morning after a high-level strategic meeting in which Alibaba focused on its full commitment to AI.

What’s interesting is that this was not a typical resignation. According to reports from reliable sources, Lin Junyang left an internal meeting due to disagreements and submitted his resignation the same day. When he informed the team, some of his colleagues cried immediately. Chen Qing, one of the key contributors to the Qwen team, commented: “I’m really heartbroken. I know that leaving wasn’t your choice.” That comment alone was enough to spread the idea that this was a completely different kind of resignation model—not a personal decision, but an administrative compulsion.

What exactly happened? The roots run very deep. Disputes over the development path of language models, a clash between the technical vision and business goals, and an organizational reshuffle that would significantly reduce Lin Junyang’s authority. Alibaba wants to transform Qwen from a technical project focused on building global standards into a commercial machine. But Lin Junyang believes that splitting the team and dismantling the lab would harm development efficiency and innovation.

The deeper issue is the contradiction between an open-source path and the objectives of the commercial group. Under his leadership, Qwen became a Chinese standard for exporting language models. By January 2026, the number of models derived from Qwen on Hugging Face exceeded 200,000, with more than one billion downloads. However, Alibaba is skeptical about the profitability of revenue from open-source models.

What’s truly worrying is the sequence that followed. In just three months, several founders of the core team resigned—the subsequent head of training and the main contributors to Qwen3.5. This looks like a collective resignation model that reflects deep dissatisfaction with the new direction.

Now the big questions: who will replace Lin Junyang? No one currently knows. The work will be distributed across parallel teams. And where will he go? The most likely scenario is that he will start his own project or join a star team in the field of embodied models.

For Alibaba, this represents a real turning point. The company is saying farewell to the phase focused on building global technical standards and is fully shifting toward a commercial cycle. But the price may be steep—disruption to the pace of R&D, wavering confidence in the open environment, and fierce competition from ByteDance and Tencent. These organizational tremors will test Alibaba’s full strategic resilience in the AI field.
