# The Implosion of the Top Open Source Lab Qwen Source: https://www.youtube.com/watch?v=aQr_FWJETOk Recap page: https://rapidrecap.app/video/aQr_FWJETOk Generated: 2026-03-09T22:01:38.506+00:00 --- ## Quick Overview The implied implosion of the Qwen open-source LLM lab stems from Alibaba Cloud CTO Zhou Jingren splitting the vertically integrated Qwen team into horizontal divisions, a decision that directly conflicted with Qwen lead Junyang Lin's belief in close integration, leading to Lin's resignation on March 4, 2026, shortly after the successful Qwen 3.5 release, despite Alibaba publicly affirming its commitment to open-source AI research. **Key Points:** - Alibaba Cloud CTO Zhou Jingren initiated organizational changes to split the Qwen team from a vertical integration model into separate horizontal divisions (pre-training, post-training, text, multimodality), which narrowed Junyang Lin's management scope. - The team's technical lead, Junyang Lin (Justin Lin), resigned on March 4, 2026, just 48 hours after the team shipped the Qwen 3.5 small model series, which received praise including from Elon Musk for its 'impressive intelligence density'. - Lin's resignation was likely driven by disagreement with the organizational split, as he advocated for closer integration between pre-training, post-training, and infrastructure teams, contrasting with the CTO's move. - Qwen 3.5 models, despite being nearly half the size (397B vs 744B) of top models like GLM-5, achieved a competitive score of 45 on the Artificial Analysis Intelligence Index, placing it among top open-source models. - Following the departure, Alibaba Cloud CEO Wu Yongming confirmed Lin's resignation approval in an internal memo (March 5, 2026), stating Alibaba would double down on its open-source model strategy, establish a Foundation Model Support Group, and increase investment in AI R&D. - Other Qwen leaders, including Kaixin Li and Binyuan Hui, also announced their departures, signaling a significant talent exodus from the project. - A tweet suggested that external customers had smoother access to Alibaba's compute than the internal Qwen team building its most important model, indicating internal resource struggles. ![Screenshot at 0:04: The video opens by showing the logo of the Qwen LLM project immediately followed by the announcement that the organization has 'imploded' following the departure of its lead, Junyang Lin.](https://ss.rapidrecap.app/screens/aQr_FWJETOk/00-00-04.jpg) **Context:** The video details the sudden departure of Junyang Lin, the technical lead of Alibaba's Qwen Large Language Model (LLM) project, on March 4, 2026. Lin was instrumental in developing Qwen, which rapidly rose in open-source rankings, even achieving high scores with smaller models like Qwen 3.5. The context for his departure involves an internal power struggle and organizational restructuring initiated by Alibaba Cloud CTO Zhou Jingren, who moved to dismantle the integrated structure Lin championed in favor of separate, horizontal teams, leading to Lin's resignation shortly after a major product release. ## Detailed Analysis The video chronicles the sudden implosion of the Qwen open-source LLM lab at Alibaba Cloud, triggered by the resignation of its tech lead, Junyang Lin (Justin Lin), on March 4, 2026. This occurred just two days after the successful release of the Qwen 3.5 small model series, which was highly praised, even receiving a repost from Elon Musk commenting on its 'impressive intelligence density' (1:21). Lin's departure was precipitated by organizational changes mandated by Alibaba Cloud CTO Zhou Jingren (1:47), who planned to split the Qwen team from its successful 'vertical integration' structure into separate horizontal divisions focusing on pre-training, post-training, etc. This move directly contradicted Lin's belief that these functions should be closely integrated (2:35). Lin's exit, which followed the separation of the model team into different departments, was described as a negative efficiency blow to Alibaba's AI ambitions (2:23). The resignation was confirmed by Alibaba CEO Wu Yongming in an internal email (6:17), which stated that Ren Xia would take over leading Tongyi Lab and a new Foundation Model Support Group would be established to coordinate resources, while Alibaba affirmed its commitment to open-source strategy despite the upheaval. Other key members, including Kaixin Li and Binyuan Hui, also left (4:36). The video emphasizes Qwen's strong performance, showing its Qwen 3.5 7B model achieving an Artificial Analysis Intelligence Index score of 45, placing it competitively against models nearly twice its size (1:28). The underlying tension appears to be a classic corporate struggle over resources and influence, where the CTO's restructuring clashed with the research team's vision, ultimately leading to the project's fragmentation. ### The Implosion - Junyang Lin resigned on March 4, 2026, just after the Qwen 3.5 release - Other leaders like Kaixin Li and Binyuan Hui also resigned - The resignation followed the CTO's plan to split the vertically integrated Qwen team horizontally ### Qwen's Success and Performance - Qwen 3.5 models achieved a score of 45 on the AI Index, competitive with models twice its size (397B vs 744B) - Qwen was recognized for pushing open-source AI research forward, leading multimodal coding agents, speech, image, and video generation (4:04) ### Organizational Conflict - The CTO's move to split Qwen into horizontal teams conflicted with Lin's belief in tight integration of pre-training, post-training, and infrastructure (2:35) - A tweet suggested external customers had better compute access than the internal Qwen team, indicating resource struggles (5:53) ### Alibaba's Response - CEO Wu Yongming confirmed the resignation and affirmed Alibaba's commitment to open-source model strategy, increasing AI R&D investment, and talent recruitment (6:17) - The CTO's strategy of splitting resources was viewed by some as self-inflicted damage (2:23) ![Screenshot at 0:01: A calendar displays March 4, the date of Junyang Lin's resignation tweet.](https://ss.rapidrecap.app/screens/aQr_FWJETOk/00-00-01.jpg) ![Screenshot at 0:18: The Qwen Technical Report lists Junyang Lin as an author from the Qwen Team, Alibaba Group.](https://ss.rapidrecap.app/screens/aQr_FWJETOk/00-00-18.jpg) ![Screenshot at 1:28: A bar chart shows Qwen 3.5 7B achieving an Artificial Analysis Intelligence Index score of 45, competitive with much larger models.](https://ss.rapidrecap.app/screens/aQr_FWJETOk/00-01-28.jpg) ![Screenshot at 2:23: A meme depicting Tom shooting himself, labeled 'Alibaba Cloud CTO' and 'Separating Qwen's Departments', illustrating the self-inflicted damage of the organizational split.](https://ss.rapidrecap.app/screens/aQr_FWJETOk/00-02-23.jpg)
