Alibaba opens a Qwen4-Max preview on Token Plan until 25 November

Alibaba Cloud's Model Studio page for Qwen4-Max-Preview says it was last updated on Nov 11, 2026. It describes Qwen4-Max-Preview as the next-generation flagship multimodal model in the Qwen family, for text generation, image and video understanding, and deep reasoning. The model id on the page is qwen4-max-preview.

The page says the model is in preview and is available through Token Plan only. It says pay-as-you-go access is not supported. It says the preview period runs from 10:00 on November 11, 2026 to 24:00 on November 25, 2026 (UTC+8), that no changes will be made during this period, and that the model will be retired after the preview ends. It lists a context length of 1M tokens and a maximum output of 393,216 tokens, shared by thinking and the final answer. It says thinking is enabled by default, with low, medium or xhigh, and that the default is xhigh. The page does not state a parameter count or a per-token price.

What it means for business: access on this page is a Token Plan preview in a fixed window, ending at 24:00 on 25 November 2026 (UTC+8), after which the page says the model will be retired. Pay-as-you-go is not offered on this page. This describes the documentation. It is not advice on sending data to the API.
