Qwen4-Max Preview opens a two-week Token Plan evaluation window
Alibaba Cloud exposed Qwen4-Max-Preview for multimodal reasoning, coding and tool use through a fixed Token Plan window from 11 to 25 November. It supports OpenAI and Anthropic-compatible APIs, but pay-as-you-go access is disabled and the preview will be retired after the window.
Why it matters: This is a deliberately time-bounded evaluation rather than a durable production endpoint. Compatibility can simplify testing, but retirement and plan constraints make it unsuitable for a new production dependency.
