Alibaba Drops the "Preview" Label From Qwen3.8-Max, Open Weights Due Next Week
On August 3, 2026, Alibaba made “Qwen3.8-Max” widely accessible through its Model Studio APIs, dropping the “preview” label the 2.4-trillion-parameter flagship had carried since its July 19 unveiling. Alibaba says an open-weight release will follow “the following week,” marking a return to open-sourcing its top-tier models after keeping several recent flagships closed.
