Qwen's model card calls Qwen3.8-Max the official version based on Qwen3.8-2.4T-A95B, whose weights are open under the Qwen3.8-Max License; that checkpoint is text-only and always thinks, and the licence requires a separate licence before commercial use by model-as-a-service or AI work-assistant businesses with revenue above US$50 million over 12 months (relaying requests to models hosted by others is excluded).
