Alibaba Launches Qwen3.8-Max, Shares Jump 6%

Alibaba launched its largest AI model, Qwen3.8-Max, causing its shares to jump 6%.

Chinese tech giant Alibaba has released its largest and "most capable AI model to date," named Qwen3.8-Max. The company claims its performance rivals top systems from US frontier labs like Anthropic and OpenAI, as well as domestic competitors such as Moonshot AI's Kimi K3. Alibaba made the model widely available, following a preview last month where it was described as "second only to Fable 5." This release led to a 6% jump in Alibaba's shares in Hong Kong.

Qwen3.8-Max boasts 2.4 trillion parameters and a 1M token context window. Alibaba's own testing suggests its performance broadly matches, and sometimes exceeds, Fable 5 on benchmark tests. On the Arena.AI text model leaderboard, Qwen3.8-Max trails only Fable 5 and three models from Anthropic's Opus family. For frontend coding, it is surpassed only by two Claude Opus models and Kimi K3, and for visual analysis, only Fable 5 outperforms it. Alibaba plans to release the weights for Qwen3.8-Max next week, marking a return to open-weight releases for its advanced models.

This launch intensifies competition in the AI sector, particularly between Chinese and US firms. The release of Qwen3.8-Max, following Moonshot's Kimi K3, highlights China's rapid advancements and increasing tempo of AI model releases. Open-weight releases are becoming a key differentiator for China's AI industry, a strategy championed by Beijing to grow its influence in global AI governance and promote domestic tech. This also comes amidst debates in the US industry about preserving access to open-weight models for safety and competition.
