Alibaba Launches Qwen4-Max Preview on Singles' Day, Ends Nov 25
Alibaba said on Nov 11 that its new-generation Qwen4 model family is coming, with flagship Qwen4-Max in preview on the Qwen AI Platform Token Plan the same day, until 24:00 on Nov 25.

What happened
At about 10:00 on Nov 11, Alibaba's Qwen account posted that 'Qwen4 is coming' and that Qwen4-Max is now in preview on the Token Plan, with early access in QwenWork, Qoder, the Qwen App and QwenStudio. Five days earlier, Alibaba posted a teaser, 'The becoming begins', without naming the model.
Under the Alibaba Cloud Model Studio Token Plan documentation, the preview model ID is qwen4-max-preview, with the alias qwen4.0-max-preview, and both IDs can be called. The preview runs from 10:00 on Nov 11 to 24:00 on Nov 25 (Beijing time) with no changes during the window, and the model ID goes offline afterwards. Calls are 80% off for a limited time, with a further 50% off for new users, for as low as 10% of list price.
Alibaba describes Qwen4 as deeper in knowledge understanding and richer in world perception, with coding and agentic capabilities advancing further, and says it beat the previous generation on real-task tests spanning complex programming, professional office work, front-end design and professional software operation; no specific tests or scores were published. As of publication, Alibaba has not disclosed Qwen4-Max's parameter count, context window, benchmark scores, open-weight plans or API pricing.
